What is a Pressure oscillator?

A pressure oscillator is a measuring device that can measure the pressure of gases and liquids. Also called a pressure transmitter. Many products output the measured pressure as an analog signal. Factories and large-scale infrastructure have many devices that control pressure constantly, so it is one of the devices that is often used in the industrial world.

A pressure oscillator is a measurement device that can detect the pressure of gas or liquid and transmit it as a signal. It consists of a sensor part that can detect pressure and an amplifier part that transmits the detected pressure as an electrical signal. The principle that allows the sensor to detect pressure is based on a semiconductor strain gauge installed on the diaphragm. When a force is applied from the outside, the diaphragm deforms, changing the resistance of the strain gauge, and converting this resistance into an electrical signal. The structure of the sensor section may be used differently depending on the type of object to be measured. The amplifier section converts the measured resistance on a printed circuit board and transmits an electrical signal. The built-in amplifier increases immunity to noise, making it possible to transmit information over long distances.
