Deployed pressure gauges have to be designed and constructed in their individual compressive strength range in relation to their resistance to cope with the highest possible operating pressure. At locations in which 2.5-times scale end value can be exceeded, e.g. between gas pressure regulating unit and incoming pressure-resistant shut-off valve or in the bypass line, pressure-resistant units have to be deployed or special measures be taken against overloading, e.g. through an excess pressure protection device (see datasheet MPV) or through the use of
a pressure gauge with higher scale end values.
