Ocean tells you how the miniature pressure sensor works.
Ocean Ocean's detailed working principle for the pressure miniature pressure sensor is as follows:
One of the more common sensors in industrial equipment is the miniature pressure sensor, which is widely used in many industries such as water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military, petrochemical, oil well, electric power, ship, machine tool, pipeline, etc. .
The working principle is that the pressure directly acts on the surface of the measuring diaphragm, and then the diaphragm will undergo small deformation. The high-precision circuit on the measuring diaphragm will transform this tiny deformation into a highly linear, proportional to the pressure. The excitation voltage is also proportional to the voltage signal, and then this voltage signal is converted to an industry standard 4-20 mA current signal or a 1-5 V voltage signal using a dedicated chip.
Pressure transmitters are used to measure the level of liquids, gases or swallow vapors. Density and pressure, and then the pressure signal is converted into 4-20mA DC signal output. The main applications of the transmitter are capacitive pressure, diffused silicon, ceramic and strain gauge pressure transmitter, etc., others are not listed one by one. Oh.
Because the measuring diaphragm of the pressure transmitter uses a standard integrated circuit, which contains linear and temperature compensation circuits, it can achieve high precision and high stability performance. The loosening circuit uses a dedicated two-wire chip. Guaranteed output of two-wire 4-20mA current signal for on-site wiring.
