221212-SERIES Pressure Transducer
Pressure Control Equipment 2011
The NOV M/D Totco Pressure Transducer converts pressure into an analog electrical signal. Converting pressure to an electrical signal is achieved by physically deforming the strain gauges which are bonded into the diaphragm of the pressure transducer and wired into a bridge configuration. Pressure applied to the pressure transducer produces a deflection of the diaphragm which introduces strain to the gauges. The strain will produce an electrical resistance change proportional to pressure.
The 221212 Series Pressure Transducer is assembled with a union and installed into an electronic pressure transducer assembly (221145 Series). It is available in flanged, threaded, or weld on sub configurations and calibration certificates are provided.
