Absolute Pressure Gauges
Compact Design
Type 516.11 - Capsule 
Element
Type 516.12 - Bourdon Tube






Applications

Measurement of absolute pressure without the effect of barometric pressure 
variation. Suitable for all clean and dry gaseous media that will not attack 
copper alloy and aluminum parts



Special Features
Size
3" (80 mm)

Accuracy
± 
1.5% of span

Ranges
Type 516.11: 10 "H2O to 400 "H2O 
Absolute
Type 516.12: 30 PSI to 200 PSI Absolute

Working 
Range
Steady: full scale value
Fluctuating: 0.9 x full scale 
value

Overpressure Safety
Type 516.11: 14.7 PSI 
absolute(atmospheric pressure)
with all scale ranges
Type 516.12: full 
scale value

Operating Temperature
Ambient: -4ºF 
(-20°C) to 140ºF (60°C)
Media: max. + 160ºF 
(+70°C)

Temperature error
Additional error when 
temperature changes from reference temperature of
68°F (20°C) ± 0.4% 
for
every 18°F (10°C) rising or falling.

Operating Principle
• The 
aluminum case holds the system pressure. The
capsule element or Bourdon tube 
is permanently sealed
with the zero reference pressure.
• The specially 
shaped capsule fully collapses to provide
overpressure safety regardless of 
the scale range.
• Any pressure applied is compared to the sealed 
reference
chamber (capsule element or Bourdon tube) to get an
accurate 
measurement of absolute pressure.
