5.2 Description of function

The sensing element, a capsule consists of two corrugated diaphragms that are assembled pressure tight at the edge.

The pressure is led to the central point of the diaphragm and acts on the inside of the capsule. The hereby produced

lifting movement is a measure for the pressure.

5.3 Description of components

5.3.2 Instrument connection

The instrument connection is located on the bottom side or at the back side of the pressure gauge and is a threaded

connection.

5.3.3 Vent valve

The vent valve for the housing is located on the top side. If the nipple is pulled out, the housing is ventilated and the

pressure which has built up in the housing due to the influence of temperature is discharged. With the valve closed,

protection class IP 65 is achieved.

5.3.4 Rear wall/plug with blow-out capability

The pressure gauge has a plug capable of blowing out on the rear wall of the housing. These act as a safety feature

pursuant to EN 837-3 and simultaneously allow for temperature compensation for the housing, via a rubber

membrane.
