Differential Pressure Gauge DN88x88 Type A18

APPLICATION

This series of pressure gauges is well suited for application in the refrigeration industry. The differential pressure gauge is specifically intended for stamping compressors for measuring suction and oil pressure.

Furthermore, it is also applicable for measuring differential pressure over oil filters in refrigeration plants.

MODULE SYSTEM

The TEMPRESS program of connecting nipples and mounting auxiliaries makes it possible to deliver thread type and mounting form as required.

The program of refrigeration scales cover most refrigeration media available on the market. The scale can be delivered with 1, 2 or 3 refrigeration media.

TEMPERATURE COMPENSATION

The unique system for temperature compensation ensures a correct reading even under heavily fluctuating ambient temperatures (0-60° c)

SAFETY

The temperature compensation system simultaneously works as blasting protection, i.e. if the measuring system blasts due to verpressure, the temperature compensation is blown out from the back of the instrument.
