PTSV 130 – TEMPERATURE AND RELATIVE HUMIDITY SENSORS WITH EXTERNAL PROBE WITH 4–20 mA
The PTSV 130 air temperature and relative humidity sensors enable temperature and humidity measurements in food, pharmaceutical, raw material warehouses, museums, archives, galleries, metrological stations, etc. The temperature and humidity measuring sensors are located in an external probe, which is connected to the electronics head by a cable. The sensor probe is placed in the measured space and cannot be disconnected from the head with electronics. The head with the sensor electronics is designed for wall mounting and, thanks to the unique design of the “S head” of SENSIT sro, its easy installation is ensured.
The output signals of the measured quantities are two galvanically isolated current signals 4 to 20 mA, set by the manufacturer as follows:
Output 1 value : relative humidity, range 4 to 20 mA corresponds to 0 to 100% RH
Output 2 value : temperature, range 4 to 20 mA corresponds to -30 to 105 °C
A calibration certificate is included in the price of the sensor.
The sensors are designed for operation in chemically non-aggressive environments.
