Q3: What is the measuring range of the differential pressure transmitter?
A3: The measuring range of this differential pressure transmitter is 0~2.5MPa (optional). It is designed for measuring differential pressure in various liquid and gas applications, with flexible range selection based on different industrial process requirements.
Tips: What causes measurement errors in a differential pressure transmitter?
Measurement errors in a differential pressure transmitter are mainly caused by temperature changes, incorrect installation, pressure overload, medium compatibility issues, and sensor calibration deviation.
- Temperature variation: Changes in ambient or medium temperature can affect sensor output. A differential pressure transmitter with temperature compensation helps reduce errors caused by temperature fluctuations.
- Incorrect installation: Improper mounting, incorrect pressure connections, vibration, or air bubbles in the process line may lead to inaccurate differential pressure readings.
- Pressure overload: Operating beyond the rated pressure range can affect sensor performance and may cause measurement deviation or damage to the sensing element.
- Medium compatibility issues: If the measured liquid or gas is not compatible with the diaphragm material, it may cause corrosion or affect measurement stability. Selecting suitable materials, such as a 316L stainless steel diaphragm, helps improve reliability.
- Calibration and sensor aging: Long-term operation may cause small measurement drift. Regular calibration and using a stable sensor core help maintain measurement accuracy.
