WIKA differential pressure gauges 711.12, 731.12describe

design

Two independent measurement systems with parallel interfaces

Standard size (mm)

100 and 160

accuracy

1.6

range

0 0.06 to 0 .. 100 MPa

The corresponding range must be selected based on the maximum total pressure applied. In heating equipment with a circulating pump, the total pressure is generally equal to the sum of liquid static pressure and pump pressure. For ease of reading, the displayed differential pressure value should not be less than 1/6 of the full range.

Please specify the following pressures when placing an order:

1) Maximum total pressure

2) Differential pressure

pressure limit

Stability: Full scale value

Volatility: 0.9 x full-scale value

Overvoltage protection: 1.3 x full-scale value

permissive temperature

Environmental temperature: -20...+60 ℃

Medium temperature: 711.12 type: maximum temperature for soft welding is+60 ℃, maximum temperature for hard welding is+100 ℃

Type 731.12: Maximum temperature of+200 ℃

Temperature influence

When the temperature of the measurement system fluctuates around the reference temperature (+20 ℃), the maximum change is ± 0.4%/10 K of the measurement range

protection grade

IP 33， Compliant with EN 60529/lEC 529 standards
