AP10 Variable Reluctance

AP10 variable reluctance absolute pressure sensor

The AP10, Absolute Pressure Sensor, is designed for low and medium pressure measurements, to laboratory accuracy, of corrosive liquids and gases. In typical AC excited bridge circuits, this transducer delivers a full-scale output of 40 mV per volt at 3kHz. The unit operates with carrier systems including the Validyne CD15 sine wave carrier demodulator and CD16 miniature DC input DC output carrier demodulator to produce a high level analog DC output suitable for recording and control.

The pressure sensing element is a flat diaphragm of magnetic stainless steel, welded between case halves of the same material, in a symmetrical assembly. Pickoff coils, embedded in the case halves, sense the diaphragm deflection. The embedded coils are covered with a non-magnetic stainless steel layer so that the pressure cavity presents a completely stainless steel exposure to the working media. One side of the diaphragm is exposed to an evacuated reference chamber. This reference chamber and the diaphragm utilize all-welded seals. No o-rings or gaskets are used in the unit.
