Type 711.11






Application
Measurement of pressure differential or duplex measurement of 2 applied 
pressures. Suitable for all gaseous and liquid media that will not obstruct the 
pressure system or attack copper alloy parts.



Standard Features



Sizes

4" & 6" (100 mm & 160 mm)

Accuracy

+ 1.5% of span

Ranges (All ranges not stocked)

Vacuum 30"Hg
Pressure from 10 PSI to 1000 PSI
Scale range must be 
selected based on the highest static pressure measured. The pressure 
differential to be indicated should be no less than 1/6 of the full scale range. 
When ordering please state both the static pressure applied and the differential 
to be indicated.

Range

Steady:3/4 of full scale value
Fluctuating:2/3 of full scale 
value
Short time:full scale value

Working Operating Temperature

Ambient:-4°F to 140°F (-20°C to 60°C)
Media:max. 140°F (+60°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. Percentage of 
span.

Weather Protection


Weather resistant (NEMA 2 / IP 33)
