SDS Smart Duct Sensor

Descriptions

SDS temperature and humidity duct mounted type transmitter provides a stable, repeatable, reliable and accurate means of measuring both temperature and humidity in the room. The polymer capacitance sensor used in the SDS is not affected by any condensation, high humidity or contaminants present in the measure environment.

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