2.2 Description
The pressure gauges in DirectDrive version do not require a movement. The measuring
element of the model 116.18.02x is designed in a helical form. The pressure element acts
as a pointer itself. The shape of the pressure element provides for a pointer rotation propor-
tional to the pressure. With this, on the one hand, the vibration resistance of the model is
increased and on the other it enables a particularly flat design.
