An instrument used to measure the difference between the pressure of a medium and the local atmospheric pressure at that time, and the measurement result will change with the variation of the atmospheric pressure.
Core Features
Most widely used: The vast majority of industrial pressure measurements use gauge pressure.
Affected by atmospheric pressure: Altitude and weather changes can slightly affect the measurement values.
Simple structure: The sensor's back is directly exposed to the atmosphere, eliminating the need for a sealed reference chamber.
Flexible range: Can measure positive pressure and also be used for positive and negative pressure ranges (-0.1MPa to 1.6MPa).
Applicable scenarios
Open container liquid level measurement: This is the most classic application. For instance, in an open water storage tank, when the transmitter is installed at the bottom of the tank, the pressure it measures is the static pressure generated by the liquid level height. Since the transmitter references atmospheric pressure, it can automatically compensate for the impact of atmospheric pressure changes on liquid level measurement, ensuring accurate readings.
Pipeline and industrial process pressure monitoring: Widely used in industries such as oil, chemical, power, it is used to monitor the pressure of gases, steam, or liquids in pipelines, ensuring the safety and stability of the process.
Complementary equipment: In water treatment, air compressors, pump control systems, and hydraulic and pneumatic equipment, it is used for pressure control and alarm.
Gauge pressure transmitters are generally not suitable for measuring high vacuum. This is because one side of it is exposed to the atmosphere. When the process side pressure is much lower than the atmospheric pressure, the huge reverse pressure difference may damage the sensor diaphragm.
