Baumer’s 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 pressure gauge complies with protection class IP65 and works on a strictly mechanical basis without using a transfer fluid to the diaphragm. This prevents pollution of the measured medium even in case of damage to the diaphragm. The DP100 is available with a wide range of hygienic 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 (option).
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 and can even withstand short peaks of up to 150 °C for use in 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 in different measuring ranges, starting from -1bar and can endure overpressures of up to 1.3 times the scale range. Its measuring accuracy complies with class 1.6 according to EN837-3. There is also a version available with 2 electrical contacts and a 4-20mA output.
Due to the fact that the DP100 pressure gauge operates without a transfer fluid to the diaphragm, it is especially popular in the pharmaceutical industry where pollution of the medium must be prevented at all costs. This is the case wherever medecins of particularly high quality or high costs are processed or where pollution of the medium would cause substantial health hazards. Extra advantage of the DP100, the diaphragm is 10 times thicker then of a standard diaphragm!!
