CAPSULE
CAPSULE gauges operate with a diaphragm connected to a dial.
They contain a hermetically sealed, evacuated and thin-walled diaphragm capsule located within the instrument. As the vacuum pressure reduces the capsule bulges. This movement is transferred via a system of levers to a pointer and the pressure can be read off on a linear scale.
As the measuring cell is hermetically sealed against the outside environment, it is not affected by changes in atmospheric pressure, making it more reliable at pressures below 10 mbar/torr.
Insensitive to vibrations
Due to the measuring system being open to the vacuum environment it is less compatible with corrosive media.
As CAPSULE gauges are better to read lower pressures, we offer it with two full scales:
1000 to 1mbar (750 to 0.75 torr)
100 to 1 mbar (75 to 0.75 torr) with the later giving better resolution at the lower pressures.
It also comes with either:
a DN 16 ISO-KF flange to connect directly to a vacuum system
a 10 mm diameter hose nozzle with integrated isolation valve for panel mounting and use on packing machines.
