3051 remote flange pressure / differential pressure transmitter

summary

3051 remote flange pressure differential pressure / transmitter the remote pressure transmitter is used to prevent the medium in the pipeline from directly entering the transmitter. The pressure sensing diaphragm is connected with the transmitter by a capillary filled with fluid. It is used to measure the liquid level, flow rate and pressure of fluid, gas or steam, such as converting it into 4 ~ 20mADC signal output after meal. 3351 pressure transmitter with remote sealing device becomes 3351 remote pressure transmitter. It has the characteristics of 3351gp pressure transmitter, which can be used to measure pressure and liquid level. It can communicate with HART manual operator, and set and monitor through it.

characteristic

Model 3051 remote pressure and differential pressure transmitter provides a reliable measurement method to avoid the direct contact between the measured medium and the isolation diaphragm of the transmitter. The transmitter with remote transmission device is suitable for the following working conditions:

1. The high temperature medium needs to be isolated from the transmitter.

2. The measuring medium can corrode the sensitive elements of the transmitter.

3. Suspension liquid or high viscosity medium.

environment

5. It is necessary to purify the measuring head strictly to replace the measured medium.

6. The measuring head must be kept clean.

7. Liquid level measurement of sealed pressure vessel.

Application

It is widely used in industries with extreme chemical and mechanical loads and high electromagnetic radiation.

matters needing attention

The measured medium can corrode the sensitive elements of the transmitter;

High temperature measured medium should be isolated from transmitter;

There are suspended solids or high viscosity media in the measured media;

The measured medium is easily solidified or crystallized when it is led by pressure pipe;

Clean the measuring head strictly when changing the measured medium;

The measuring head must be kept clean and pollution is strictly prohibited;

Object of use: corrosive or viscous liquid.
