Due to the high pressure typical during oil production and processing, the devices provide a solid front and a blow-out back for maximum security. The watertight instruments can be filled with dampening liquid. A special compensation diaphragm maintains high accuracy even with filled devices. For processes like alkylation, where temperatures of more than 400°C can be reached, a capillary tube can be mounted in front of the pressure gauge to reduce the temperature of the measuring device.Baumer Ltd.www.baumerprocess.com44 (0) 870.161.3000
