What are the standard methods for checking the tightness of pressure transmitters?

From: Issued date 2021.03.25 Back

Today, Wotian pressure transmitter manufacturers come to share with you the standard methods of pressure transmitter tightness check:

 

1. Increase the pressure smoothly (or evacuate), so that the pressure in the measuring room of the transmitter reaches the upper measurement limit (or the local atmospheric pressure 90% evacuated).

 

2. Cut off the pressure source, seal for 15 minutes, and observe through the pressure gauge within the last 5 minutes, the pressure value drop (or increase) must not exceed 2% of the upper measurement limit.

 

3. When the differential pressure transmitter performs a leak check, the high and low pressure chambers are connected, and the high temperature pressure transmitter is customized. At the same time, the rated working pressure is introduced for observation.
