Measurement principle
The pressure gauges in DirectDrive version do not require a movement. The pressure element is directly connected to the pointer or acts as a pointer itself. The shape of the pressure element provides for a pointer rotation proportional to the pressure. The measuring elements of the model PG81 are designed in a spiral form and those of the model PG91 in a helical form.
The advantage of the DirectDrive version is the optimised shock and vibration resistance.
Fields of application
This pressure gauge is particularly suited for the operating conditions of pressure regulators and pressure valves on fixed and portable gas cylinders.
