S.M. Gauge Company Limited - vacuumgauge.co.uk

Operating Principle:
The case, machined from solid aluminium bar, retains the system pressure, whereas the pressure element of the capsule constitutes the zero pressure datum.
The special design of the capsule enables it to collapse fully to provide overpressure safety independent of the scale range.

Service intended:
Measurement of absolute pressure excluding the effect of barometric pressure variation.
Suitable for all clean and dry gaseous media that will not attack copper alloy and aluminium parts.

Design:
Pressure safety gauge with evacuated pressure element inside

Nominal Size:
100mm

Scale ranges:
0-25 to 0-1000 mbar absolute pressure.
Dual scale with Torr.

Working pressure:
Steady: full scale value
Fluctuating: 0.9 x full scale value

Overpressure safety:
1 bar absolute (atmospheric pressure)

Operating temperature:
Ambient: -20..... + 60°C
Medium: + 70° maximum

Zero adjustment:
By means of adjustable screw from the back of the case
