Operating principle
- The case machined from solid aluminium bar retaines the system pressure, whereas the pressure element of either the capsule or the bourdon tube type constitutes the zero pressure datum.
- The particularly shaped capsule fully collapses to provide over-pressure safety independent of the scale range.
- Any pressure applied is measured against the sealed pres sure datum to exclude the effect of ambient pressure variation.
