Size
    4?"

   Accuracy
    Grade 2A acc. to ASME B40.1 Standard (+ .5% of full span)

    Pressure Ranges (EN / ASME)
    0 ... 10 up to 0 ... 15,000 psi resp.
    0 ... 0.6 up to 0 ... 1000 bar,
    also all vacuum and compound ranges

    Pressure Limitations
    Steady pressure:   full scale value
    Cyclic pressure:   90% of full scale value
    Temporary:         130% of full scale value

   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. +100 °C (+212 °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
    ?" 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
    Thermoplastic PBTP black, with integral rear flange (fire retardant and impact resistant acc. to UL 94 VO);
    Model RPG 4?" fillable, model RPGG 4?" 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)

    Model code:    RPG 4?" = dry version (fillable)
                   RPGG 4?" = filled version,
                   filling fluid glycerine

    Wetted parts:  316 stainl. steel = ordering code: –3
                   (others see above)

    Pressure range: according to EN 837-1 resp. ASME,
                    e.g. 0/60 psi or 0 - 4 bar or 600 psi

    Connection thread: ?" NPT (= standard)
                    or others (see above)
