This type of differential pressure gauges can be used with liquid, gaseous, aggressive, non-viscous and non-crystallizing media, even in aggressive environments. Their task consists of measuring differential pressures or two different gauge pressures, such as in refrigeration engineering.
Moreover, a simultaneous measurement of steam pressure and the resulting steam temperature are possible. Two independent indicating Bourdon tube measuring systems work In a stable stainless steel case. Both pointers turn around the same axle and give + and - pressure separately.
The pointer of the low-pressure side has the shape of a dial. On this dial the pressure difference can be read directly up to 50% of the measuring range. In addition, the two individual pressures are also directly readable. In case of high dynamic pressure loads and vibrations, a good damping are achieved with a liquid filling.
