When it comes to industrial processes and engineering, there is the essence of accurate and reliable measurements. It correlates to safety, super performance, and efficiency. The differential pressure sensor is one of the most vital instruments that can guarantee effective measurements.
Advanced sensors are crucial in obtaining pressure readings and monitoring pressure differences. It makes it possible for project managers to make informed decisions based on precise data. Below we will guide you through the technology of differential pressure sensors, their applications across different sectors, and associated benefits so you can understand them better.
Understanding Differential Pressure Sensors
Differential pressure sensors are designed to measure the difference in magnitude of pressure between two points in a system. By comparing pressure at two different locations, these sensors allow for great accuracy and enhanced readability, making them ideal for demanding applications requiring precision.
Based on their piezoresistive principle, some differential Pressure Sensors may offer a flexible solution to fold differential pressures ranging from 350 mbar to 35 bar, where this OEM silicon pressure sensor is apt for varied fluid media and welding constructions with good sensitivity and accuracy. Differential pressure sensor configurations may also cater to varying industrial needs. Power supply options may span from 4mA DC to 20mA DC with higher output voltage for extra demanding uses.
Working Principle and Types of Differential Pressure Sensors
There are normally two options when it comes to the pressure transducers’ operations. Either you go for the mechanical or electrical differential pressure transducers.
As for the Mechanical differential, pressure sensors utilize physical components, like the Bourdon tubes or bellows, to detect pressure variations. These sensors have been here for a long time and are most suitable in areas where the applications need low precision.
On the other hand, electronic differential pressure sensors utilize semiconductor-based technology. They offer higher accuracy and sensitivity than piezoelectric sensors since they use crystals which generate an electric charge when subjected to mechanical stress. Capacitive sensors measure changes in capacitance caused by pressure variations.
These electronic sensors are best suited for precise measurement applications such as aerospace, medical devices, and advanced.
