Differential pressure transmitter is the most commonly used weight transmitter in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.

The selection of pressure and differential pressure transmitters is mainly based on the measured medium, temperature environment, accuracy level, installation and maintenance costs, etc. After determining the manufacturer and model of the transmitter used, determine the variable according to the use requirements. range of the transmitter.

Siemens pressure transmitter​ SITRANS P differential pressure series adopts silicon sensor of Siemens patented technology. The modular dsiii series and P310 series are composed of sensor unit with EEPROM, local button with magnetic induction and electronic module of EEPROM. The sensor unit includes pressure sensor and temperature sensor.

Because the production process of the transmitter is very complicated, there are situations where the transmitter cannot work normally due to the unreasonable internal parameter settings of the transmitter, resulting in problems such as the failure of the entire system to operate normally and the switch tripping.

The pressure range of 351GP can reach 4psi. The 351GP is equipped with a fully configurable liquid crystal display (LCD), which can display pressure and diagnostic information. Small, light, easy to install and transport.

Cerabar S uses ceramic, anti-overload metal sensor and function monitoring. Communication via HART, PROFIBUS PA or FF. Measure the absolute pressure and gauge pressure of gas, steam or liquid in various occasions.

Modular instrument components can be interchanged and linked with the modules of the differential pressure-static pressure-pressure measuring instrument (Deltabar-Deltapilot-Cerabar M): Replaceable display unit; General electronic components.

Press key to adjust zero: After entering the interface, apply zero point (4 mA point) pressure to the transmitter, and wait for the transmitter to display stable values. Press the key for 2 seconds, the transmitter will output 4.000mA current and complete the zero adjustment operation (LCD screen display: LSET).
