Schaller LF-TD 150 Digital Humidity and Temperature Transmitter

• Industrial Transmitter for Humidity and Temperature

  Humidity transmitter for maximum temperatures of 150°C for laboratory, air conditioning and drying technology, wood processing, food, feed, construction and paper industries, printers, agriculture, biotechnology and medicine.

  In manufacturing processes, further processing, storage and transport, the exact measurement of humidity and temperature is playing an increasingly important role. High product quality can only be ensured through precise moisture monitoring.

  The LF-TD transmitter series from Schaller Messtechnik in its robust and easy-to-install aluminium housing is ideally suited for this purpose. A 750mm long robust probe tube (Ø 12mm) made of stainless steel with a screwed-on sensor cap expands the application possibilities of the LF-TD 150 temperature and humidity transmitter. Various sensor caps (steel sintered, bronze sintered, plastic with or without filter paper and many more) are available as optional accessories.

  As standard, the humidity and temperature values are output by means of an analogue 4-20mA current output. Optionally, other interfaces such as RS232, Profinet, Modbus or USB can also be selected for the temperature and humidity transmitters.

  An optional display offers an additional expansion of the range of applications, on which the current humidity and temperature values can be read.

  Two optional relay outputs enable the control of e.g. alarms or ventilation directly from the humidity and temperature transmitter. These switching outputs can be freely configured directly on the LF-TD 150 humidity transmitter. (Switching points, hysteresis)

  The problem-free connection to an existing system is guaranteed by the supplied 1.9 meter long connection cable including overmolded, robust sensor connector (sensor side). The second side of the cable is equipped with ferrules for easy connection, e.g. in the control cabinet.

  The capacitive humidity sensor used guarantees long-term stable accurate measurement results and is resistant to normal contamination and many chemicals. The sensors installed in the humidity transmitters are also characterized by very rapid adjustment behavior.

  The high measurement accuracy of the LF-TD series is ensured by a factory calibration at six moisture points. A calibration certificate is available on request.
