Characteristics of intelligent remote differential pressure industrial pressure transmitter:

1 need to heat medium and transmitter isolation

2 measuring medium sensitive to the original transmitter.

3 suspension or high viscosity medium

4 measured medium due to environmental or process temperature changes and solidification or crystallization.

5 replace the measured media need to strictly clean the measuring head.

6 measuring heads must be kept clean and hygienic.

7 sealing pressure vessel level measurement.

Intelligent remote differential pressure industrial pressure transmitter

1, the measured medium on the sensitive element of the transmitter corrosion;

2, the need to be measured by the media and transmitter isolation;

3, the measured medium solid suspension or high viscosity medium;

4, the measured medium by the pressure guide tube at the same time easy to cure or crystallization;

5, the replacement of the measured media need to strictly purify the measuring head;

6, the measuring head must be kept clean, no pollution.

7, the use of objects: corrosive or viscous liquid

Application of intelligent remote differential pressure industrial pressure transmitter
