Pressure Sensor Fundamentals

Sales contact



Pressure sensors are the core of electronic pressure measurement systems and supply information that is vital to the operation of processes and equipment. Pressure sensors work by changing pressure, a physical variable, into a quantity that can be processed electrically. Once in an electronic format, the signal is then interpreted by computers, digital panel meters or other devices to display, record and/or change the pressure in the system being monitored. For example, in heavy equipment such as mining trucks, pressure sensors embedded in the rear suspension system ensure the load doesn’t exceed capacity to prevent damage, which can impact productivity or even safety.
