• Differential pressure gauge with integrated working pressure gauge DELTA-plus Model 702.03.100 (see data sheet PM 07.15)
• Differential pressure gauge with integrated working pressure gauge and microswitch DELTA-comb, Model 702.02.100 (see data sheet PM 07.16)
• Differential pressure switch DELTA-switch, Model 851.02.100 (see data sheet PM 07.17)
• Differential pressure transmitter DELTA-trans, Model 891.34.2189 (see data sheet PM 07.18)

These differential pressure gauges are particularly intended for flow safeguarding in heat transfer oil plants according to DIN 32 727 and in hot-water apparatus according to VdTÜV note of instructions "flow 100". This gauge has been designed for connection to standard throttling devices (e.g. orifice gauges, nozzles or similar) that operate according to the differential pressure principle and are interconnected via differential pressure lines and shut-off devices.

 

Apart from the display of the differential pressure, these applications require, as a rule, the display of the current working pressure.For this reason, a working pressure gauge is integrated in the differential pressure gauge DELTA-comb as a standard feature. An additional measuring point involving additional expenses forpiping and mounting is thus no longer required.

 

The white dial of the working pressure gauge distinctly stands out against the blue background of the display of the differential pressure gauge, thus enabling a quick and safe reading of both quantities to be measured.
