The MPG and MPE Series are suitable for extreme environmental conditions in applications with crude oil and seawater. Some processes produce hydrogen sulphide, an extremely corrosive gas corroding even stainless-steel sensors; therefore, the sensors of ranges MPJ and MPF are equipped with a Monel sensing element, according to the NACE standard requirements for applications in the oil industry.
Due to high pressure during oil production and processing, devices provide a solid front and a blow-out back for maximum security. The watertight instruments can be filled with dampening liquid and a compensation diaphragm guarantees high accuracy even with filled devices.
The environment is less polluted in refineries than in oil fields. In these areas, suitable pressure gauges include Series MEX5 and MEP5, mounted in stainless-steel cases and available with sensing elements of stainless steel 316L or Monel. For processes like alkylation, where temperatures may exceed 400 °C, a capillary tube can be mounted in front of the pressure gauge to reduce the temperature of the measuring device. For applications with heavy oil or tar, gauges are installed on chemical seals adhering to the compatibility of the diaphragm material with the fluid. A range of materials such as Monel, stainless steel, or tantalum are available for these uses.
