Pressure Gauge Diaphragm Pressure Gauge with Hygienic Process Connection

Pressure gauges that operate without transfer fluid are particularly popular wherever media of particularly high quality are processed or where pollution of the medium would cause substantial health hazards. A diaphragm pressure gauge specially designed for hygienic processes is Baumer's new DP100.

The DP100 diaphragm pressure gauge is a pressure measuring device specially designed for hygienic processes encountered in fields such as the production of pharmaceuticals and foods. The gauge complies with protection class IP65 and works on a strictly mechanical basis without using a transfer fluid. This prevents pollution of the measured medium even in case of damage to the diaphragm.

The DP100 is available with a wide range of standard connections. All components in contact with the medium are made of stainless steel 1.4435 (316L). The membrane has a surface roughness of Ra < 0.5 µm. The bayonet ring housing of the DP100 is made of stainless steel 1.4301 and welded to the process connection. Either laminated glass or a special flat glass for instruments can be chosen for the window. The pressure gauge can be operated at ambient temperatures of -20…60 °C. The instrument can endure a maximum media temperature of 80 °C during continuous operation. According to the company, the device withstands short peaks of up to 150 °C making it appropriate SIP (sterilisation in place) processes. A version of the instrument which can be completely sterilised in an autoclave is available upon request.

The pressure gauge is available for the measuring ranges 0…6°bar, 0…10°bar, -1…5°bar, and -1…9°bar and can endure overpressures of up to 1.3 times the scale range. Its measuring accuracy complies with class 1.6 according to EN°837-3.
