What are pressure sensors usually used for?
Pressure sensors are generally used:1. pressure measurement of a meter, with two meters, you can read the pressure value and record pressure change process, through the calibration of pressure readings, accuracy higher than the pressure gauge, and the pressure remote telemetry.2. pressure safety protection can be applied.3. automatic control of the operation of the pressure system.Therefore, the pressure sensor is a common instrument for automatic control of pressure machines.
Said pressure sensor is simple, is the pressure signal into electrical signals: 0~10V voltage signal to current signal, or 4~20mA, the feeling of different pressure value, corresponding to a current value of this range, or voltage value, these signals can give automatic control equipment to transmit. For example, the inverter servo, can also be transmitted to the computer, PLC, PC, to realize the operation process automation / unattended.
Pressure sensor: pressure transducer definition: sensor that senses pressure and converts it into usable output signal.The range of use is too wide. The pressure sensor is one of the most commonly used sensor in industrial practice, which is widely used in various industrial control environment, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil, electric power, shipbuilding, machine tools, plumbing and other industries.More intuitive uses;1, directly used for the determination of various pressures: air pressure, water pressure, hydraulic pressure (including water pressure), people's blood pressure measurement in life;2. Pressure sensors are used in automobiles, some high-end motorcycles, and almost all internal combustion engines;3 、 liquid level meter: all kinds of liquid level measurement in the field meter, mostly pressure sensors;4. The weighing signals of most electronic weighing devices and truck scales are also pressure sensors.5. Pressure sensors are also used for acceleration measurements in Aeronautics and astronautics.
