Pressure Sensors


pressureThe Smart Pressure Device SPD series of pressure sensors are silicon based and encapsulated in modified plastic Dual in Line packages. The output voltage of the sensor is linear to the applied pressure.


In case of an absolute version the reference vacuum chamber is formed on the die during manufacturing.
Due to fact that the bridge resistance values, the SPD pressure sensor is especially suited to use in combination with the Universal Transducer Interface (UTI03).


Various pressure ranges are available; full scale ranges from 0.350 to 6.5 Bar. Other ranges can be made on request.
Excitation Voltage is typical 5 V (0 – 10 V AC/DC).
Bridge resistance is typical 3.3 KO.
Wetted materials are: glass, ryton, silicon, fluorsilicon and gold.
