The differential pressure transducer or differential pressure transmitter are all differential pressure sensors. It is called differently while means the same in most situations depending on the countries and companies as differential pressure transducers are mostly used in the USA. In Micro Sensor, we call the sensitive element a differential pressure sensor that usually outputs a millivolt signal. The differential transducers and differential pressure transmitters usually output digital signals like 4mA DC-20mA DC, Modbus, HART, etc.
Precautions for Differential Pressure Sensor Installation
• Ensure that the pressure on the high-pressure side of DP sensors is not less than the pressure on the low-pressure side.
• When installing and using the pressure-sensitive element, please keep it as horizontal as possible. This approach is to reduce the influence of installation inclination angle on the measurement accuracy of sensitive components.
• External resistors to compensate for temperature drift: It is recommended that the external resistors be connected as close as possible to the differential pressure-sensitive components.
