Pressure transducer
Pressure transducers are used for measuring the pressure of a fluid or air in a device or system. A pressure transducer provides to downstream display, control, or regulating devices an electrical output signal in the form of an output signal voltage or output signal current that is a measure of the pressure measured. Pressure transducers may typically provide two types of outputs which include a cable connection for transmitting a signal representative of the sensed pressure to a remote monitoring or control device and a human-readable display for providing a local reading of the sensed pressure. Pressure transducers that use piezoresistors are formed with a silicon substrate and an epitaxial layer, which is grown on the substrate. A portion of the substrate is removed, leaving a thin, flexible diaphragm portion. The piezoresistors are located in the diaphragm portion to form a pressure transducer. Capacitive pressure sensors typically include a stationary electrode having a rigid, planar conductive surface forming one plate of a substantially parallel plate capacitor and a deformable conductive member. A generally known pressure transducer assembly for measuring fluid pressure includes at least one fluid measuring line going between the process circuit and the valve of the pressure transducer. Tire pressure transducers are mounted on a wheel inside a tire and detect air pressure within the tire. An air pressure transducer includes a radio frequency transponder that responds to received radio frequency signals. A differential pressure transducer is used for measurement of differential pressure. Differential pressure transducers are widely used for example in the chemical industry, food industry, aviation industry, in water treatment plants, etc. for purposes of among others flow measurement in flowing media, the control of filters, speed measurement in aircraft or water craft. Measuring diaphragms with differential pressure transducers are frequently used to ascertain fluid flow-through.
