Description:

Temperature sensors are employed in heating and air conditioning systems for both civil and industrial purposes. Connected to the relevant OMNIA series controllers, they allow detecting and controlling room, immersion, duct and outside temperature. This series includes also sensors fitted with potentiometer for the adjustment of the set point of the controller, they are connected to. The sensors detect temperature through a sensing element, whose ohm value varies according to the detected unit. Each sensor is characterized by the sensing element type, which determines its ohm/°C function, and by the application. All sensors are provided with a direct variation sensing element (ohm value increases when the temperature increases). All sensors must be connected to the controller by means of two wires, in order to receive the ohm signal generated by the corresponding sensing element.
