How a Pressure Sensor Works on an Air Compressor?
Pressure sensors are an essential component of a wide range of instruments, from space exploration to smartphones. They are also widely used in many mechanical industries, including air compressors. Pressure sensors are needed to accurately monitor the pressure in the machines and provide critical data for monitoring and control purposes.

In the past, compressors were responsible for increasing pressure and raising the intake pressure state to the exhaust pressure state. Compression ratio is the technical performance of compression, that is, absolute pressure on high pressure side divided by absolute pressure on low-pressure side.
Compression ratio must be calculated with absolute pressures value. In order to avoid a negative calculation value for compression ratio, absolute pressures, instead of gauge pressures, should be used when calculate pressures ratio. Only using absolute pressures values, can compression ratio have positive calculation values which are very meaningful.
what role do sensors play in an air compressor?
So, combining the two, Now let’s take a look at the application of pressure sensors in industrial air compressors.

A pressure sensor on an air compressor is a device used to measure the amount of pressure in the air being compressed by the machine. Air compressors typically operate at pressures between 2HP and 10,000HP. As air with contaminants or pollutants passes through the compressor, the efficiency and lifespan of the compressor can be greatly reduced.
The pressure sensor monitors any drop in pressure as dust and other particles are filtered off; if it detects that pressure has dropped below 10 PSI it will trigger an alarm system in the circuitry to alert operators to clean or change out filters accordingly. Pressure sensors have a broad range applicable ranges, connecting to virtually any microcontroller, and gel protection and anti-magnetic stainless steel casing helps protect their core components. These can be employed for smartphones, tablets, personal navigation devices, or even tire gauges!
