SIS – Smart Immersion Sensor

SIS temperature immersion type transmitter provides a stable, repeatable, reliable and accurate means when it comes to measuring temperature in a pipe or tank. The polymer capacitance sensor used in the SIS is not affected by any condensation, high humidity or contaminants present in the measuring environment.

Equipped with miniaturized electronics, the SIS sensor is inter-changeable, therefore it requires no recalibration at all. Its Sophisticated integrated circuits design provides a full humidity and temperature compensated 4-20mA-output signal. The SIS enclosure is made of ABS plastic. Its plug and play design enables a rapid & easy installation, hence minimizing installation & maintenance costs.
