3.3.5 Use as a leak indicating unit for residual pressure monitoring of pressurized gas cylinders
In the case of leak detectors that work with compressed gas such as
nitrogen, a residual pressure message can be useful in order to be
able to prepare a replacement of the cylinder in good time. For this
purpose, a contact manometer attached to the pressure reducer with
a set limit value triggers the alarm or the message on the leak indicat-
ing unit as soon as the residual pressure falls below the set limit val-
ue.
The connection is usually made on channel 1.
For a connection diagram, the circuit diagram, and an installation ex-
ample, see Chap. 5.4 and 5.5.4.
