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 Aluminum alloy, black figures, white background  

Pointer Aluminum alloy black, micrometer adjustable  

Case and Ring Black Phenolic, with integral rear flange (fire retardant and impact resistant acc. to UL 94 VO);   Model RPG 115 StD fillable, model RPG 115 StL with case filling glycerine  

Safety Features Solid front between measuring system and dial with full blow-out safety back. Should the Bourdon tube rupture, the entire case back separates, allowing full relief.  

Blow-out Back Same material as case and ring, hinged for safety (will not become a projectile).  

Compensation Diaphragm Elastomer (ready for filling, no fill kit required!)  

Lens Laminated safety glass (4 mm / .16" thick)
