Pressure transmitters for SIS/DCS systems

SIS/DCS systems use pressure transmitters, and explosion-proof pressure transmitters use high-precision and high stability pressure sensor components from internationally renowned companies. After high reliability amplification circuits and precision temperature compensation, the absolute or gauge pressure of the measured medium is converted into standard electrical signals such as 4-20mA, 0-5VDC, 0-10VDC, and 1-5VDC. High quality sensors, fully sealed welding packaging technology, and sophisticated assembly processes ensure the quality and performance of the product. This product has multiple interface forms and lead methods, which can meet the needs of customers to the greatest extent possible. It is suitable for use with various measurement and control equipment in SIS/DCS systems.

Product Description:

3351DP/GP type differential pressure/pressure transmitter with remote transmission device

After the 3351DP/GP transmitter is equipped with a remote transmission sealing device, it becomes a 3351DP/GP remote transmission differential pressure/pressure transmitter.

3351DP/GP remote differential pressure/pressure transmitter is a reliable measurement method that avoids direct contact between the measured medium and the isolation diaphragm of the transmitter,

It is suitable for the following situations:

1. When the tested medium has a corrosive effect on the transmitter connector and sensitive components;

2. When it is necessary to isolate the high-temperature measured medium from the transmitter;

3. When there are solid suspended solids or high viscosity in the measured medium that can easily block the transmitter connector and pressure chamber;

4. When the tested medium is easily solidified or crystallized when led out with a pressure tube;

5. When replacing the tested medium, it is necessary to rinse and not mix it together;

6. Hygiene conditions must be maintained to prevent contamination.

The 3351DP/GP type remote differential pressure/pressure transmitter with remote sealing device still has various characteristics of the 3351DP/GP type differential pressure/pressure transmitter. Provide a variety of structural materials and welding structures for remote transmission device components, with strong reliability. The low volume design of the filling chamber reduces temperature impact, and according to user requirements, DC200 series silicone oil is filled for a usage temperature of -40 to+149 ℃; The use temperature of high-temperature silicone oil is -15 to 315 ℃. The upper limit of the working pressure of the remote transmission device is the rated value selected by the user for the remote transmission device; The working pressure shall not be less than 3.5kPa (absolute pressure).
