Pressure Transducer Technology; A Basic Introduction
A pressure transducer is an electro mechanical sensor which is used to measure the pressure in a process or environment, and provide an electrical signal as an analogue of the measured value. There are many types of pressure transducer used in industry, with varying performance, measurement ranges and size, depending on the application. The main type of pressure transducer can be categorized as follows:
Piezoresistive pressure transducer This consists of a pressure diaphragm fitted with fixed resistors. Under the pressure-induced strain, the resistors change their value. The resistors are arranged in a Wheatstone bridge and this produces a voltage output proportional to pressure
