These heavy duty industrial gauges, are manufactured with either a mild steel or aluminum case and bezel, [black epoxy coated], or with a stainless steel case and bezel.
General construction is with a brass, bar type movement, fully adjustable, beryllium copper capsule with brass connection block. Alternatively, for the more aggressive environment, a stainless steel connection and capsule is available.
Atmospheric is used as the reference pressure. Changes in the measuring pressure causes the capsule to expand, this expansion is in proportion to the applied pressure, this is then transmitted to the instrument pointer by means of a fine precision movement. This is then indicated as a deflection on the gauge dial.
For use in the measurement of low pressure and vacuum gases, which are compatible with the gauge materials.
