Pressure transmitters are sensors that generate analog or digital signals based on the amount of pressure applied over liquids or gasses. Pressure transmitters include an electronic amplifier and a pressure transducer in a single package so that measured data can be sent to long distances without introduction of electrical noise or loss of accuracy. For their use in process automation industries, the transmitter harvests signals typically conformed to a 4 - 20 mil-ampere standard. Pressure transmitters find varied application in food & beverage, chemical, and automotive industry. Pressure sensors in the automotive industry are generally used for engine control such as manifold, fuel, oil, boost, and barometric pressure among others. Pressure sensors also find applications in systems such as power steering, transmission pressure, brake pressure, and nitrous pressure, and exhaust gas recirculation (EGR) among others.
