There are many different types of pressure sensors that are used to measure a number of applications and operations. From use in automobiles, measuring flow rates in pipelines, density measurements, and even for measuring the levels of fluids, a differential pressure sensor can be the best option.
The Basics of Operation
The differential pressure sensor is a method of measurement based on two different reference pressures. The sensor is designed to allow access to either side of a diaphragm by the liquids or gases. This creates a pressure against the central diaphragm on both sides.
A gauge is used to read or measure changes in the pressure on either side of the central diaphragm. This can include an increase in pressure on one side, or a drop in pressure on the other. The sensor measures the deformation of the diaphragm, and converts this change into an electric signal.. It can also transmit that information directly through USB, wireless, or other digital methods to computer systems that monitor, record, and control the flow or another variable.
Signs of Failure
The most common issue with a differential pressure sensor is damage to the diaphragm that causes it to be deformed, or to lose the ability to flex and respond to changes in pressure.
This is most often caused by extreme bursts of pressure that are atypical for the system. It can also be caused by installing the wrong size or type of sensor, given the operating conditions.
Another issue that can occur is damage to the port area of the sensor. This may occur if there is some type of debris or contamination within the system that lodges in the port or the tube, restricting the correct flow of the fluid into the sensor.
