Wiznet makers

Overview

Managing temperature and humidity in production and storage environments involves more than checking a reading. Measurements also need to be recorded and compared over time. Schaller Messtechnik’s humimeter LF-TD-E is a fixed-installation transmitter that measures relative humidity and temperature and makes those readings available over Ethernet. The manufacturer supplies it as a finished instrument with a sensor probe and aluminium enclosure under article number 13082. (Official product page)

The WIZnet connection appears in the instrument’s network-configuration procedure. Its operating manual instructs users to discover and configure the Ethernet module with a WIZnet configuration tool. The product brings together environmental measurement, Ethernet connectivity, and PC-based data management in a commercial instrument. (Operating manual)

About Schaller Messtechnik

Schaller Messtechnik GmbH is a specialist measurement-instrument manufacturer based in St. Ruprecht an der Raab, Austria. Founded by Max Schaller in 1995, the company states that research, development, and manufacturing take place at the same location, with electronic assembly and final verification measurements performed in Austria. (Who We Are)

Its humimeter brand covers instruments for measuring air humidity and the moisture content of grain, biomass, wood, paper, cardboard, and building materials. The portfolio includes handheld instruments, fixed sensors, data-management software, and calibration and repair services. Within this range, LF-TD-E is a product for collecting humidity and temperature data over a wired network. (humimeter website)

What Is LF-TD-E?

LF-TD-E is an instrument installed at a fixed measurement location to report air temperature and relative humidity to an external system. Rather than requiring repeated visits with a handheld meter, it allows measurements from the installed sensor to be accessed through a network and managed with PC software. (Product application information)

Supplier information identifies applications including server rooms, warehouses, building management, greenhouses, manufacturing facilities, museums, and galleries. These are suggested application areas, not evidence of named customer installations. (Product application information)

Main Specifications

The table follows the manufacturer’s German-language technical information. The full measurement range and the calibration range associated with the accuracy specification are different. These are manufacturer-published figures, not independent test results. Power is supplied separately through USB Mini-B. (Manufacturer technical information)

How It Works

AI-generated image

The basic workflow is measure humidity and temperature → transfer readings over Ethernet → view and record them on a PC. The sensor and measurement electronics produce the readings, while the network interface makes them accessible externally. Storage and analysis are functions of the connected PC software. (Official product page)

Printed page 11, “Find the transmitter,” in Operating Manual v1.1 describes the initial connection procedure. The user compares the MAC address discovered by the WIZnet configuration tool with the label on the Ethernet module, configures the IP address and port, and then establishes a Telnet connection through a terminal program. The documented initial access method therefore uses a network configuration tool and a terminal, rather than a browser dashboard. (Official operating manual, page 11)

Role of WIZnet

Evidence in the Instrument’s Configuration Procedure

Source: Schaller.com

The LF-TD-E manual directs users to the WIZ108SR product page to obtain the configuration tool and instructs them to discover the instrument’s Ethernet module with WizNet Config Tool. This is more specific evidence of WIZnet involvement than the presence of an RJ45 connector alone. (Operating manual)

However, WIZnet provides the tool for both WIZ107SR and WIZ108SR. The documentation therefore supports the use of a WIZnet-based network configuration, but confirming the exact installed module requires product-specific component information or a readable module marking. The manual reference alone is not sufficient to identify it conclusively as WIZ108SR. (WIZ108SR documentation)

A Communication Interface, Not a Sensor

This WIZnet Serial-to-Ethernet product family transfers serial-device data over TCP/IP and returns incoming network data to the serial device. Considered alongside the LF-TD-E setup procedure, the WIZnet component can be understood as the interface connecting the measurement electronics to the PC network. The publicly available material does not establish the instrument’s exact internal serial wiring or electrical interface. (WIZ108SR documentation)

The sensor and measurement electronics determine humidity and temperature. WIZnet’s role is to make that measurement data available over the network.

HumiSenseWare: Turning Readings into Records and Analysis

Source: Schaller.com

Schaller provides HumiSenseWare for managing data from the LF-TD product family. Published functions include live tables and graphs, local database storage, Excel export, and network sensor discovery. (HumiSenseWare)

The software offering separates basic visualization, data-management and recording options, and additional sensor capacity. The manufacturer also lists an expansion package for three additional sensors, supporting configurations with multiple measurement points. Not every software function or sensor allowance is included with an LF-TD-E purchase; the required licence and options depend on the selected configuration. (Manufacturer product and accessory information)

LF-TD-E measures conditions at the installation site. HumiSenseWare provides the PC-side tools that turn those measurements into time-based records and comparison data.

Market Context and Published Supply Figures

LF-TD-E belongs to the market for fixed environmental measurement in production, storage, and building environments. Supplier information highlights locations such as server rooms, warehouses, and production facilities where readings need to be managed away from the measurement point. (Product application information)

For broader context, Grand View Research estimates the global humidity-sensor market at approximately US$1.4 billion in 2024, with a forecast of approximately US$2.5 billion by 2030. Its coverage includes automotive, industrial, building-automation, and consumer applications. These figures do not represent the market for Ethernet humidity transmitters alone or the addressable market of LF-TD-E specifically. (Humidity Sensor Market)

There is also a manufacturer-level shipment figure. In a November 10, 2021 announcement, Schaller stated that it shipped more than 5,000 professional moisture and humidity measuring instruments worldwide each year. This describes the company’s entire product range at that time—not LF-TD-E sales or the number of WIZnet modules used. LF-TD-E-specific cumulative sales and installation counts were not established in the reviewed public sources. (Schaller’s 2021 announcement)

Products and Purchasing Channels

LF-TD-E is supplied as a finished instrument combining a sensor probe and enclosure, rather than as a sensor-development board. It is listed through the manufacturer’s enquiry channel and external specialist suppliers. (Official product page)

The AZPLUS figure is the price displayed on the sales page reviewed on September 14, 2026. It is not a global manufacturer price or an average transaction price. Stock, lead time, and included items need to be confirmed when ordering. A product listing does not establish the number of units sold. (AZPLUS listing)

Grubatec states that its product is supplied without cables or a power adapter. Schaller also lists power adapters, mounting brackets, calibration equipment, and factory calibration certificates as accessories. The complete installation therefore needs to be considered separately from the instrument’s base price. (Grubatec product page)

The company’s Lifetime Support offering describes access to consultation, training, and repair support over the product’s service life. It is not a statement that all repairs and replacement parts are free for life. (humimeter website)

Position Within the Schaller Product Range

Schaller offers different connectivity options across its humidity and temperature product range.

LF-TD-E is therefore a wired Ethernet measurement option, not a single product combining every interface in the wider range. Wireless or Profinet features—and any WIZnet implementation in other models—cannot be assumed to apply to LF-TD-E. (LF-TD product family, LF-TD Profinet, huminode)

Social Media and Product Communication

LinkedIn — Applications, Training, and Partner Activities

Schaller Messtechnik’s official LinkedIn page features humidity-monitoring applications, grain-moisture measurement, trade shows, and distributor training. Reviewed posts included technical training for staff from Brazilian partner Elof Hansson and participation in Agrishow.

Rather than presenting specifications alone, these posts show where measurements are made, how instruments are used, and what training or support accompanies them. (Schaller Messtechnik on LinkedIn)

Videos and the Blog — Demonstrations and Measurement Knowledge

The company operates an official YouTube channel and features demonstrations of grain and wood-chip measurement instruments on its website. Its technical blog covers topics such as the difference between calibration and adjustment, water activity, and biomass moisture measurement. (humimeter website)

These activities cover the company’s broader portfolio. They are not LF-TD-E-specific advertising results, but they show a communication approach that combines product explanations, measurement demonstrations, and technical education.

Why This Product Matters

LF-TD-E combines a sensor and enclosure with Ethernet connectivity and PC software for recording and analysing measurements. Networking serves a practical purpose: connecting a fixed measurement point to the data-management workflow. (Official product page)

For WIZnet, the application demonstrates Serial-to-Ethernet technology used as a communication interface in a professional instrument. The manufacturer’s device-discovery and IP-configuration instructions show how networking enters the product’s actual setup process. Public information does not establish cost savings, improved measurement accuracy, or reduced development time as Schaller’s reasons for selecting WIZnet. (Operating manual)

Current Status and Limitations

The sensor-tube material requires confirmation for the supplied configuration. The manufacturer’s introductory product text mentions stainless steel, while the German technical table identifies plastic. The current sensor tube should therefore not be conclusively described as stainless steel. The IP40 rating in this article follows the manufacturer’s German specification for the electronics enclosure. (Manufacturer technical information)

WIZ108SR, the product referenced by the manual, is marked as discontinued in WIZnet’s documentation. This does not mean that LF-TD-E itself has been discontinued. It does mean that the exact module and configuration tool applicable to a currently supplied instrument should be confirmed with the manufacturer. (WIZ108SR documentation)

These references compare ways of connecting sensor data to Ethernet. They do not imply that LF-TD-E uses W5500, MQTT, or Modbus. (Temperature and humidity monitoring project, CO2_Gateway)

Conclusion

humimeter LF-TD-E is a commercial instrument for measuring humidity and temperature at a fixed location and connecting those readings to PC-based data management over Ethernet. Its published offering combines measurement specifications, manufacturer and reseller supply channels, software, and support. (Official product page)

WIZnet’s role is not to produce the sensor readings, but to make measurement data accessible over the network. Although the exact installed module requires further confirmation, the manual’s WIZnet configuration procedure documents a specific relationship between Ethernet-module technology and a professional measurement product.
