The differential pressure gauges of the DELTA-line product family are primarily used for the monitoring and control of low differential pressures where there are high requirements in terms of one-sided overpressure and static pressure.
Typical markets for these products are the shipbuilding industry, process heating technology, the heating, ventilation and air-conditioning industries, the water/wastewater industry, and machine building and plant construction. For these, the main function of the measuring instruments is the monitoring of filters, compressors and pumps. These instruments are primarily used as flow monitors in heat transfer oil plants.

Wherever a differential pressure must be displayed locally and, at the same time, electrical circuits need to be switched safely dependent on a defined differential pressure, the DELTA-comb finds its use.
