wika 711.12 731.12 Differential Pressure Gauges with Bourdon Tube Parallel Entry

Applications

Measurement of differential pressures or of two different pressures applied

Heating, ventilation and air-conditioning

For gaseous and liquid media that are not highly viscousor crystallising

Model 731.12 for aggressive media also

Special Features

Scale ranges from 0 ... 0.6 bar

Differential pressure with moving dial

Economical and reliable

Description

Design

2 independent measuring systems, parallel entries in line

Nominal size in mm

100, 160

Accuracy class

1.6

Scale ranges

0 ... 0.6 to 0 ... 1000 bar

Scale range must be selected in relation to the highest total

pressure applied!

In heating plants with circulating pumps, the overall

pressure is usually defined as equal to the hydrostatic

pressure plus the pump pressure.

In order to ensure a good readability, the pressure differential

to be indicated should be no less than 1/6 of the full

scale range.

When ordering please state both pressures:

a) maximum pressure applied, b) differential pressure

Pressure limitation

Steady: full scale value

Fluctuating: 0.9 x full scale value

Short time: 1.3 x full scale value

Operating temperature

Ambient: -20 ... +60 °C

Medium: Model 711.12: +60 °C maximum (soft soldered)

+100 °C maximum (brazed)

Model 731.12: +200 °C maximum

Temperature effect

When the temperature of the measuring system deviates

from the reference temperature (+20 °C):

max. ±0.4 %/10 K of full scale value

Ingress protection

IP 33 per EN 60 529 / lEC 529
