MEP5 safety pressure gauge with stainless steel connection
Baumer's new safety pressure gauge MEP5 has been specifically designed for use in corrosive atmospheres and fluids. It has a diameter of 100mm and can measure pressures from -1 to 0 and 0 to 1600 bar at gauge working temperatures of -20 to 70°C. According to Baumer, it has a stainless steel housing, sensing element, fully welded process connection and complies with protection class IP67.
The MEP5 also contains a special compensating diaphragm which maintains accuracy by equalising internal and external atmospheric pressures. It is said to be particularly suitable for applications in the chemical industry as well as in heavy vehicles, energy production and oil and gas plants such as the French TOTAL refinery. Special versions with connection sizes specified by the customer are available upon request. This is said to prevent leakage and allow the correct positioning of the measuring instrument. A baffle wall and a blow out back have been implemented to prevent the operator from risk of injuries in case of failure of the sensing element.
The thermal drift of the device is ±0.4% for a variation of ±10°C in relation to the reference temperature 20°C. The gauge may be used on transient fluid temperatures of up to 200°C providing that the temperature of the gauge itself does not exceed 70°C.
The MEP5 boasts an accuracy class of 1 according to European norm EN 837-1 and is available with 22 mm square G1/2 or 1/2NPT process connections. Its window is made of safety laminated glass 4 mm thick. Optionally, the watertight gauge can be filled with a dampening fluid. The device conforms to S3 Safety as defined by European norm EN 837-1 as well as to Pressure Directive PED 97/23/CE and has a Lloyd's Register Approval certificate.
