A pressure transducer is a device which converts an applied pressure into a measurable electrical signal. As shown in the figure, passive transducer will produce variation in the passive element in accordance with the variation in the non-electrical input quantity (or signal). They produce an output signal in the form of some variation in resistance, capacitance, or any other electrical parameter, which then has to be converted to an equivalent current or voltage signal. A tire pressure sensor is an example of a gauge pressure measurement equipment. Pressure transducers can come in a number of shapes and sizes, but the majority of transducers have a cylinder-shaped center which houses the diaphragm and the measurement pressure chamber, a pressure port at one end which is typically a threaded, bolted, barbed fitted, or open, and on the other end a location for signal transmission. In the following example, two channels of the 1756-IF8 are wired in Single-Ended Mode. Example: Maximum total loop resistance = V(subsmax) - V(subsmin) / I(submax . Passive transducer requires external power supply. There are various types of transducers depending upon the change in property or the energy they bring about to measure specified physical quantities. By transduction used.
