The LF-TD 120 is a high accuracy relative humidity and temperature transmitter up to 120°C, ideal for laboratory, climate control and drying technology, wood processing, food and animal feeds, building industry, printing and paper, agriculture, biotechnology and pharmaceutical industry.

Features:

In manufacturing processes, storage and transport, the exact determination of moisture and temperature becomes increasingly important. Only accurate moisture monitoring can guarantee high product quality.

The LF-TD 120 transmitter, with its robust and easy to mount aluminum housing, is best suited for all applications in this field. A robust sensor tube of 500mm length (Ø 12mm) made of stainless steel with screwed sensor cap is an add-on enlarging the application potential. Diverse sensor caps (steel sinter, bronze sinter, plastic with or without filter) are available options.

In the standard version, the moisture and temperature values are output via analogue 4-20mA power output. Alternatively, they can also be used with other interfaces such as: RS232, Profinet, Modbus or USB.

The optional available display showing the current moisture and temperature value is an add-on enlarging the application possibilities of the transmitter.

Two optional relay outputs enable the direct control of an alarm or air conditioning, for example. These switching outputs can be configured freely (switch-points, hysteresis).

Thanks to the enclosed 1.9 meter connection cable with a 5-pole molded and robust sensor connector (on the sensor side), the sensor can be connected to existing plants without any difficulty. The other end of the cable is equipped with wire end ferrules for easy connection to the control box or something similar.

The used capacitive moisture sensor ensures long-time stable and accurate measuring values and is resistant to normal pollution and a lot of chemicals. Furthermore, the sensor used in the LF-TD 120 transmitter is characterized by rapid conditioning.  

The measuring accuracy of the LF-TD 120 is guaranteed by an optional factory-calibration at six humidity points.
