Measurement principle
The DirectDrive pressure gauges 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 element of the model PG81 is designed in a spiral form and that of the model PG91 in a helical form.
The advantage of the DirectDrive version is the optimised shock and vibration resistance.
Range of use
This pressure gauge is particularly suited for the operating conditions of pressure regulators and pressure valves on fixed and portable gas cylinders.
