The pressure gauge is of the bourdon tube type, which has a circular formed tubular spring with an oval cross section. The pressure in the system influences the bourdon tube internally so that an increase in pressure tends to straighten it. The free end of the bourdon tube gives a movement proportional to the internal pressure. The movement is then transferred via the measurement unit to a movement/indicated value on the scale. The pressure gauge has a red adjustable pointer to indicate the maximum allowable pressure.
AT 8306A has a built in electronic creep contact type 811, which is adjustable through the glass. The indicators can be set all over the scale range. The socket has a double function and closes under rising and falling pressure. Cable performance on the page Pg 7.

Pressure gauge with electric socket in dampened or industrial performance after request.
The pressure gauges should be mounted so that they are easy to read and protected against vibrations, heat, cold and high humidity. During high media temperatures a water worm pipe should be used. For pressure variations and vibrations a dampening fluid filled gauge should be used.
The cables are marked with numbers. Electric installation according to schematic.
