Selection Tips of pressure gauge
Pressure gauge must be selected in terms of scale range and design.
The scale range is optimally selected when the operating pressure lies in the middle third of the scale range.
The pressure gauge must be mounted free from vibration and should be aligned so that it is easy to read.
The process connection must be sealed properly.
The installation of a shut-off device between pressure tapping and pressure gauge is recommended for maintenance and replacement.
For non-hazardous, liquid media < 25 bar without case filling, no safety level is required.
