LF-TD-TA Humidity transmitter up to 60 °C
Humidity-temperature transmitter with analog output / for maximum temperatures of 60°C/ standard 4-20 mA output / optional interfaces / selectable humidity measurands
The LF-TD-TA humidity-temperature transmitter with analog output is an optimal solution for accurate humidity and temperature measurements in various industries, such as laboratory, air-conditioning and drying, wood processing, food, feed, construction and paper industries, printing, agriculture, biotechnology and medicine.
With a maximum temperature of 60 °C, this humidity transmitter is suitable for a wide range of applications in these industries.
The LF-TD-TA humidity-temperature transmitter has an analog output that includes a 4-20mA current output as standard, but optionally supports other interfaces such as RS232, Profinet, Modbus or USB.
An optional display allows easy reading of the current humidity and temperature values, while two optional relay outputs enable direct control of alarms or ventilation. These switching outputs can be freely configured (switching points, hysteresis).
The LF-TD-TA humidity-temperature transmitter is easy to mount and use, and offers high measurement accuracy ensured by factory calibration at six humidity points. A calibration certificate is available upon request.
Application area
The exact measurement of humidity and temperature is becoming increasingly important in manufacturing processes, further processing, storage and transport. Precise humidity monitoring is essential to ensure high product quality.
