The programmable sensors are intended for temperature measurements and measurements of relative humidity of air in air conditioning ducts. The plastic connection head is provided by the cable ending. Easy mounting of the temperature sensor is ensured by the unique " S head " design invented by SENSIT s.r.o
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 1: relative humidity, range 4 to 20 mA is related to 0 to 100 % RH
- The value on the output 2: temperature, range 4 to 20 mA is related to -30 to 120 °C
A calibration sheet is included in the sensor price.
The sensors are designed to be operated in a chemically non-aggressive environment.
DECLARATION, CERTIFICATION, CALIBRATION
- EU Declaration of Conformity – in accordance with Act 22/1997 Coll. on technical requirements on products as amended.
- Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard, as amended) or in an Accredited laboratory.
