These pressure gauges are based on the proven Bourdon tube measuring system. On pressurisation, the expansion of the Bourdon tube, proportional to the incident pressure, is transmitted to the movement and indicated.

Bourdon tube pressure gauges for refrigeration technology use the direct relationship between pressure and temperature to indicate both vapour pressure and vapour temperature. The multiple scale indicates the measured pressure and the converted temperature of the refrigerants.
