Temperature and humidity sensors for interior and outdoor usage with 4–20 mA output

The programmable sensor is intended for temperature measurement and measurement of relative humidity of air. The sensors enable to measure temperature and humidity in food, pharmaceuticals and raw material stores, museums, archives, galleries, meteorological stations etc. The sensor is designed for wall mounting. It consists of electronic circuits placed in the durable plastic box with the connection terminal board and the sensing element for temperature and humidity located in the cover.

Digital conception with microprocessor provides long-term stability of parameters, temperature compensation of the humidity sensing element and failure state signaling. The most up to date polymeric sensing element for humidity guarantees stability of indication and resistance to condensation water.

Two galvanically separated current signals 4 to 20 mA are available as output signals of the measured variables; the outputs are set by the producer as follows:

the value on the output I1: relative humidity, range 4 to 20 mA is related to 0 to 100 % RH

the value on the output I2: temperature, range 4 to 20 mA is related to -30 to +80 °C.

A calibration sheet and program TSensor for sensor configuration by means of USB cable SP 003 are included in the sensor price. The sensors are designed to be operated in a chemically non-aggressive environment.

Used sensing elements: Pt 1000/3850
