![]() ![]() Pressure sensors allow more specialized maintenance strategies, and they can predict and prepare for risk failures because they work on real-time data.Īpplications that have a pressure sensor installed mean that maintenance teams are alerted when necessary, allowing them to address the issue immediately. ![]() Pressure is defined as the amount of force (exerted by a gas or liquid) applied to a unit of ‘area’. Despite which term is used, they all produce an output signal and measure pressure. ![]() Those include pressure transducers, pressure transmitters, and pressure indicators, among others. There are several common terms often used interchangeably to describe pressure sensors. To learn more about other types of sensors, see our related guides that cover the different types of humidity sensors, and temperature sensor types, or to learn about other measurement devices, see our full range of guides. This article will discuss the different types of pressure sensors, describe the working principles, and review which common applications utilize them. Pressure sensors are used to control and monitor a wide range of everyday applications, including indirect measurements of gas/ fluid flow, speed, altitude, and water levels.īecause of their wide range of uses in applications, they vary drastically in technology, design, performance, stability, and cost. Pressure is defined as the force required to stop a fluid from expanding, typically displayed as force per unit area. Pressure sensors are extremely useful devices that measure the physical pressure of gases or liquids via a sensor and output signal. There are seven main types of pressure sensors: Aneroid barometer pressure sensors, manometer pressure sensors, bourdon tube pressure sensors, vacuum (Pirani) pressure sensors, sealed pressure sensors, piezoelectric pressure sensors, and strain gauge pressure sensors. Finally, the charge signal needs to be converted by a charge amplifier to a voltage which can then be read.In addition, the optimized diaphragm ensures accurate dynamic pressure measurements, even when the diaphragm is simultaneously exposed to a high thermal shock.Pressure sensors help notify maintenance teams of risks before serious failures occur, allowing corrective action to take place. The compressed crystal produces a charge which is proportional to the pressure. The pressure to be measured acts on the sensor’s diaphragm and compresses the PiezoStar crystal. This PiezoStar crystal gives the sensor a far higher sensitivity than an equivalently sized pressure sensor based on synthetic quartz, which results in a lower noise level and so enables lower pressure to be measured more accurately. At the core of the all-welded, hermetically sealed 601C series there is a high performance PiezoStar crystal grown by Kistler. By contrast, piezoresistive pressure sensors are the right choice when measuring static pressure curves. Another unique characteristic of piezoelectric pressure sensors is their ability to measure small pressure fluctuations that are superimposed on top of high static pressures with exceptional resolution. Due to their high natural frequencies, piezoelectric pressure sensors can be used for a variety of applications where dynamic pressures need to be measured.
