Temperature Limitations
Ambient temperature: -40 up to +60 °C (-40 up to +140 °F)
with glycerine filling: -20 up to +60 °C (-4 up to +140 °F)
with special oil filling: -40 up to +60 °C (-40 up to +140 °F)
Medium temperature: max. +315 °C (+600 °F)
Temperature Caused Error
The accuracy error caused by media or ambient temperatures differing from +20 °C (+68 °F) is significant. It can be estimated with .4% per each 10 °C (18 °F).
Protection Type
IP 65 (EN 60529 / IEC 529)
 
Standard Configuration
Connection
½" NPT bottom connection 316 stainless steel (1.4571)  
Bourdon Tube
316 stainless steel (1.4571), argon arc welded  
600 psi resp. 40 bar and below = C-form  
800 psi resp. 60 bar and above = helical  
Movement
Stainless steel  
Dial
