Basic information :

Diaphragm seals are used to prevent process medium form entering directly into the pressure-sensing assembly of the differential pressure transmitter.

Please read the product samples and instructions carefully before installing the pressure transmitter, and the pressure interface should not leak during installation to ensure that the range and wiring are correct.The shell of the pressure sensor and the transmitter should be grounded normally. The signal cable shall not be mixed with the power cable, and the sensor and transmitter should avoid strong electromagnetic interference.

It is possible to avoid direct contact with the diaphragm of the transmitter.

This method can be applied to the followsituations:

1. The tested medium has the corrosive effect on the transmitter sensor

2. It is necessary to isolate the high temperature measurement medium from the transmitter

3. Solid suspended or high viscosity medium in the measured medium

4. The measured medium is easily solidified or crystallized by the primer tube

5. The measuring head should be strictly purified by changing the measured medium

6. The measuring head must be hygienic and strictly prohibited from pollution.Use object: corrosive or viscous liquid

There are four types of remote transmission devices for dual-flange remote liquid level transmitter:

1. Flat remote transmission device (standard 3, working pressure: 2.5mpa)

2. Screw mounted remote transmission device (maximum working pressure is 10MPa)

3. Flange mounted remote transmission device

4. Insert cylindrical remote transmission device (standard 3 "or 4", working pressure 2.5MPa)
