Before discussing further about differential pressure sensors, it is better to understand what a pressure sensor is. In theory, pressure is an expression of the force exerted on a surface per unit area. A pressure sensor is a device that converts pressure into small electrical signals that are sent and displayed. The pressure sensor detects pressure and can determine the amount of pressure by measuring the electric charge. Usually, this tool is used to measure the pressure of liquids, air, and other gases. There are several pressure sensor devices that are often applied in the industrial sector; they are Gauge Pressure Sensors, Absolute Pressure Sensors, and Differential Pressure Sensors. The differential pressure sensor works by measuring two sensor differences (high and low) , the value of the pressure difference being the result of the Differential Sensor. It is usually used to measure the pressure level of a substance in a closed tube.
It is very important to understand some important points when choosing a differential pressure sensor. First of all you need to understand that a differential pressure sensor has the task of measuring the difference between two or more pressures level. You need accurate values as input to an industrial process feedback system. The value that appears on the sensor will be valuable data to ensure that the industrial process runs within the desired parameter range.
Thus, differential pressure sensors play an important role in every industrial process to avoid confusion about pressure ratings. The pressure rating describes the difference between pressure values such as gauge pressure or absolute pressure. Highly accurate pressure sensors are indispensable in pressure gauges to protect against extreme environments, such as in industrial of oil, gas and chemical applications; where in these areas the system will definitely experience vibration and corrosion.
Data sources from differential pressure sensors are useful for monitoring pressure in industrial piping systems. The measurement of differential pressure will be the basis for industrial measurements such as flow, altitude, density, viscosity, even for temperature measurement. Differential pressure is not affected by changes in fluid pressure, temperature pressure or other things such as environmental and weather influences. Good differential pressure sensors work by reading the differential pressure accurately, precise parameters, and various influencing factors and sending signals to represent the differential pressure displayed in other places such as the control room.
So, do you want to apply good pressure management to your industry? If yes, then you should use a Differential Pressure Sensor from Strainsense which can be used for various applications including filter blockage detection or HVAC.
