Product Details of Air Compressor Pressure Sensor
Product Overview
The air compressor pressure sensor is a device specially designed for air compressors, which can accurately convert the mechanical pressure of gas inside the air compressor into an electrical output signal. It is composed of a pressure - sensitive element suitable for the working environment of the air compressor and an efficient electronic conversion element. It can monitor the pressure of key parts such as the air compressor's air storage tank and pipeline in real - time to ensure the safe, stable and efficient operation of the air compressor.
Adaptation Range
It is applicable to various types of air compressors, including piston air compressors, screw air compressors, centrifugal air compressors, etc. Whether it is a small household air compressor or a large industrial air compressor, a corresponding model can be found for matching.
Working Principle
It works based on the piezoresistive effect. Its core pressure - sensitive element is made of special materials, which can accurately sense the subtle changes in gas pressure inside the air compressor. When the pressure inside the air compressor changes, the resistance of the pressure - sensitive element changes. This change is converted into an electrical signal through a Wheatstone bridge circuit, which is then processed by electronic components and output, providing accurate pressure data for the control system of the air compressor.
Product Types
-
Air Storage Tank Pressure Sensor: Specifically used to monitor the pressure in the air storage tank of the air compressor, ensuring that the pressure of the air storage tank is within a safe range and preventing safety accidents caused by overpressure.
-
Pipeline Pressure Sensor: Installed on the gas transmission pipeline of the air compressor, it monitors the gas pressure in the pipeline in real - time to ensure the stable transmission of gas.
-
Intake Pressure Sensor: Monitors the pressure at the air intake of the air compressor, providing a basis for the intake regulation of the air compressor and optimizing the working efficiency of the air compressor.
Specification Parameters
-
Pressure Range: Usually 0 - 1.6MPa, 0 - 2.5MPa, 0 - 4MPa, etc., which can be selected according to the working pressure requirements of the air compressor.
-
Accuracy: Up to ±0.2%FS, which can meet the strict requirements of air compressors for pressure monitoring accuracy.
-
Output Signal Type: Common ones include 4 - 20mA current signal, 0 - 10V voltage signal, and some models support RS485 digital signal output, which is convenient for docking with the control system of the air compressor.
-
Operating Temperature Range: -20℃ - 80℃, which can adapt to the temperature changes when the air compressor is working.
-
Operating Humidity Range: 5% - 95%RH (no condensation), which can work normally in a relatively humid environment.
-
Protection Level: IP67, with good dustproof and waterproof performance, suitable for the complex working environment of air compressors.
Main Functions
-
Pressure Monitoring and Control: Monitor the pressure inside the air compressor in real - time. When the pressure reaches the set upper limit, send a signal to the control system to stop the air compressor; when the pressure drops to the set lower limit, prompt the air compressor to start, ensuring the stable output pressure of the air compressor.
-
Safety Protection: If the pressure of the air compressor rises abnormally, the sensor can feed back in time to trigger safety devices such as safety valves, avoiding damage to the air compressor due to overpressure or even dangerous situations such as explosion.
-
Energy - Saving Optimization: By accurately monitoring the pressure, the air compressor can operate within a reasonable pressure range, reducing unnecessary energy consumption and improving energy utilization efficiency.
