Reuger pressure gauge selection

[helpyou]

HI

I have two questions please

1. I have five reuger pressure gauges to choose from, minor differences, but range is same. May be they 'll all work. how to choose? application is in a corrosive envirnoment, range 0-10 bar, process temperature -161 C.

2. in pressure gauge details, process fluid temperature range is not mentioned (range in which gauge can operate and not fail). Is this normal? I checked in Reuger manual, it says process temperature max 100 C, but doesnot say minimum Temp.

Thank you

Take a look at the latter part of Ashcroft’s app note on using gauges at cryogenic temperatures - they recomment capillary tubing to allow the desdhead capillary volume to warm to ambient.
