CHAPTER 4 | GAS PRESSURE TRANSDUCER

4.3

NOTES

•

Ensure that all system connections are secure and leak free. Hydrogen leakage may cause fire 
or explosion in extreme cases. 

•

If the pressure port of the transducer is blocked by a foreign object, do not use a sharp tool to 
clear the passage. It is recommended to dissolve the foreign object in a solvent instead.

•

Do not tamper with the device. Contact us for re-calibration purposes.
