With the advancement of instrument technology, differential pressure transmitters of various brands are developing in the direction of high precision and intelligence.

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.

In this case, consider whether the pressure source itself is stable; Degree of anti-interference ability of instrument or pressure sensor; Whether the sensor wiring is normal; Vibration and fault causes of the sensor itself; Whether the power polarity is connected reversely. Check the power supply voltage, verification equipment and set value of the transmitter (4mA and 20mA points); Check whether the pressure interface leaks or is blocked;

It is an instrument that converts non-standard electrical signals into standard electrical signals. There are many kinds of transmitters. The transmitters used in industrial control instruments mainly include temperature transmitter, pressure transmitter, flow transmitter, current transmitter, voltage transmitter and so on. The transmitter is equivalent to a signal amplifier.

EJA pressure transmitter is a commonly used pressure transmitter product, mainly for measuring gas, liquid, steam and other media in the industry, and is widely used in many fields.

When the differential pressure transmitter is installed too close to the upstream of the production line, unmelted materials will wear to the top of the sensor.

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.

Rosemount 3051T transmitter integrates sensor, electronic technology and single isolation diaphragm design to realize the calibration range of gauge pressure and absolute pressure measurement from 0.3 to 10,000 psi.

Adopt single crystal silicon resonant sensor The direct output of the sensor is the frequency signal, which can be directly connected with the single-chip microcomputer.
