Approx. 45" through 2 pointer revolutions.
diameter: 8 ½"
element volume: Ranges 150 psi and below: 6.9 cc
with pointer at zero; 8.6 cc, at full scale. Ranges 200 psi and above: 10
cc. For the range 0-125 water only: 6.3 cc with pointer at zero; 8.0 cc,
at full scale
service: Gauges with ranges of 200, 300, and 500 psi (Bourdon tubes)
can be calibrated for liquid service as optional. The 0-1000 psi range is
calibrated for liquid service only.
pressure: Cases are open to atmosphere.
Ranges of 200, 300, and 500 psi (Bourdon tubes), when calibrated for
liquid service, have bleed tubes to facilitate filling and flushing. On
the 1000 psi range a bleed tube is standard.
connections: 150 psi and below, 1/8" female NPT; 200 psi and above, ¼"
female NPT. Both have a builtin stainless steel filter and are located in
the bottom of the case.
construction: Anodized aluminum with tempered-glass dial cover; flush
mounted by three screws through the bezel.
adjustment: The zero-adjusting screw is accessible through both the
