Digital relative humidity and temperature sensor with hx processor UPSI France

This module, intended to quantify the relative humidity level and temperature in the ambient atmosphere, is made of a micro-system SPSI UPSICAP MSS Bi-Face G-TUCN.32 type that delivers a variable frequency proportional to humidity, and a resistive temperature sensor (thermistor NTC).
The micro-system making this probe, integrates a humidity cell created in-situ on the upper side of the substrate, while the lower side carries the temperature sensor, the electronic transmitter and the plug-in connector. This functional module is associated to a support with output connection. The surface electrode cell which is directly in contact with water vapor is connected to ground (0V).
It can be associated with modules H-TUTA.32 or H-UTA.32 (output 4-20 mA two wires by independant channel). The micro-system module and the substrate of the connector-supply are protected from harsh environment by full moulding, and the sensig side to humidity, can be covered with high efficient atmospheric filter to reduce electrical effects of condensation.
This technology is a major step forward in the field of sensor-transmitters with long-term stability and reduction of mass production cost.
