Compact pressure transmitter, standard compact pressure transmitterDetailed information:

pressure transmitterThere are mainly capacitive pressure transmitters, diffusion silicon pressure transmitters, ceramic pressure transmitters, strain gauge pressure transmitters, etc.
Pressure transmitters can be divided into three types based on their pressure measurement range: general pressure transmitters (0.001MPa~35MPa), micro differential pressure transmitters (0-1.5kPa), and negative pressure transmitters.Exquisite pressure transmitter, standard exquisite pressure transmitter/transmitter series
pressure transmitter(Kehao) is the process of converting mechanical signals such as water pressure into electronic signals such as current (4-20mA). The pressure and voltage or current are linearly related, usually in a proportional relationship. Therefore, the voltage or current output by the transmitter increases with the increase of pressure, resulting in a relationship between pressure and voltage or current. The two pressures of the measured medium of the pressure transmitter are introduced into the high and low pressure chambers, and the pressure in the low pressure chamber is atmospheric pressure or vacuum, acting on the isolation diaphragms on both sides of the δ element (i.e. sensitive element), and transmitted to both sides of the measuring diaphragm through the isolation diaphragms and the filling liquid inside the element. A pressure transmitter is composed of a measuring diaphragm and electrodes on both sides of the insulating film, each forming a capacitor. When the pressure on both sides is not equal, it causes displacement of the measuring diaphragm, which is proportional to the pressure difference. Therefore, the capacitance on both sides is unequal. Through oscillation and demodulation, it is converted into a signal proportional to the pressure.Exquisite pressure transmitter, standard exquisite pressure transmitter/transmitter series

Compact pressure transmitter, standard compact pressure transmitterPerformance

5. The pressure sensor directly senses the pressure of the measured liquid level, without being affected by the foaming or deposition of the medium.
Compact pressure transmitter, standard compact pressure transmitterDuring use, the following situations should be considered:
1. Prevent the transmitter from coming into contact with corrosive or overheated media;
2. Prevent sediment from settling inside the conduit;
3. When measuring liquid pressure, the pressure tap should be opened on the side of the process pipeline to avoid sedimentation and slag accumulation;
4. When measuring gas pressure, the pressure tap should be opened at the top of the process pipeline, and the transmitter should also be installed at the top of the process pipeline to facilitate the injection of accumulated liquid into the process pipeline;
5. The pressure pipe should be installed in a place with small temperature fluctuations;
6. When measuring steam or other high-temperature media, it is necessary to connect a buffer tube (coil) or other condenser, and the working temperature of the transmitter should not exceed the limit;
7. When freezing occurs in winter, transmitters installed outdoors must take anti freezing measures to prevent the liquid in the pressure inlet from expanding due to freezing volume, which may cause damage to the sensor;
8. When measuring liquid pressure, the installation position of the transmitter should avoid the impact of the liquid (water hammer phenomenon) to prevent damage to the sensor due to overpressure;
9. When wiring, thread the cable through the waterproof joint (accessory) or flexible tube and tighten the sealing nut to prevent rainwater and other substances from leaking into the transmitter housing through the cable.
