Process Control And Instrumentation
Differential pressure transmitters. These instruments are used to detect pressure. The sensing element is connected to the process by pipe work and flexes in proportion to the pressure. The resulting distortion produces an electric signal that is amplified and converted to a value on a read-out. Keywords: pressure sensor, strain gauge, tank level, process pressure, pressure difference. A typical sensing element is a strain gauge of piezoelectric crystal such as quartz, which produces a voltage across its opposite faces when under mechanical stress that produces an electric signal proportionate to the pressure. The process side of the sensor sees the pressure to be measured while the other side is connected to a reference pressure.
