wika Differential Pressure Gauges wika 711.11 with Bourdon Tube Element Vee Entry

Applications

Measurement of differential pressures or of two different pressures applied

For gaseous and liquid media that are not highly viscous or crystallising and will not attack copper alloy parts

Heating, ventilation and air conditioning

Special Features

Differential pressure with moving dial

Cost-effective and reliable

Scale ranges from 0 ... 0.6 bar

Description

Design

Two independent measuring systems, vee entry 60°

Nominal size in mm

100, 160

Accuracy class

1.6

Scale ranges

0 ... 0.6 to 0 ... 60 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: 3/4 x full scale value

Fluctuating: 2/3 x full scale value

Short time: full scale value

Operating temperature

Ambient: -20 ... +60 °C

Medium: +60 °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
