Design Considerations for Diaphragm Pressure Transducers Assume that a diaphragm pressure transducer is to be designed for a maximum rated pressure of 1000 psi [6.89 MPa], under which pressure the output (e o) from a steel diaphragm should be 2 mV/V. The structure of the pressure transducer includes a force collector namely an elastic diaphragm as well as a transduction component that uses an inductive, dependent resistive, capacitive technique to generate an electrical signal. Technical specification . Model 188/288/388 from GP:50 is a family of all welded stainless steel miniature flush diaphragm pressure transducers. The first pressure transducers had mechanical-force-summing elements that converted energy into mechanical displacement, or deformation, and then coupled the generated force to a recording device. This allows the transducer to effectively support higher viscosity fluid pressure measurements without port clogging or plugging. Pressure sensor is the most commonly used sensorin industrial practice. The silicon diaphragm is protected from the media by an oil-filled 316SS isolation diaphragm; they react in tandem to process fluid pressure. The model IPT-20 (with pressure port) / model IPT-21 (with flush diaphragm) process transmitter is available in seven case variants. Some LVDT pressure transducers are fitted with a single, precision metallic diaphragm with over range pressure protection stops as the pressure-responsive element. Richard Teplick, in Foundations of Anesthesia (Second Edition), 2006. This type of pressure sensing element is usually subjected to the pressure media on one side only. This pressure difference causes the diaphragm or crystal to flex, and the resultant displacement . The movement of the core is used to vary the induced current generated by an AC powered primary coil on another secondary pick-up coil.
