After the LH-3851/1851DP/GP transmitter is equipped with a remote transmission sealing device, it becomes the LH-3851/1851DP/GP remote transmission differential pressure/pressure transmitter.

LH-3851/1851DP/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:

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

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

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 LH-3851/1851DP/GP type remote differential pressure/pressure transmitter with remote sealing device still has various characteristics of the LH-3851/1851DP/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 -20 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). The selection of isolation membrane materials for corrosive media can be found in the appendix, which is only for reference by users when selecting.
