5 Technical information pplication are used for electronic pressure measurement in many industrial and building applications. Various measuring principles, output signals, materials, pressure transmission liquids and process connections allow pressure transducers to be used in almost any application. Pressure transducer versions are available for abrasive, pure, highly viscous, viscous or crystallising media as well as special models for hygienic processes. Typical applications areas Pneumatic/hydraulic Gas industry Process engineering Pharmaceutical and biotechnology applications Chemical industry and petrochemical industry Medical technology Laboratory applications Food applications Water treatment Waste water applications Mechanical and plant engineering utomation Filter monitoring Heating, refrigeration, air conditioning utomotive industry Connection technology with numerous versions, diffusion-tight and extremely robust: pressure transducer DMU 02 Vario Description convert physical pressure into an electrical signal proportional to the pressure. Different pressure transducer versions are available which use a variety of measuring principles serving as the basis for sensing the pressure. Measuring principle and measuring cell Piezo-resistive polysilicon stainless steel measuring cell (thin film) n isolation layer made of non-conductive silicon oxide is coated to the stainless steel diaphragm (a high-precision part calculated in view of the force path) on the side facing away from the pressure; after that, polysilicon is deposited. Semiconductor resistors are etched from this layer; a gold layer provides contacts. When pressure is applied and causes a deflection, the resistance changes. s compared to conventional strain gauges (conductors), polysilicon semiconductor sensors have a higher output signal. Since the measuring cell is made of stainless steel, it can be directly welded to the process connection. This helps to prevent leaks caused by fatigue of the sealing material. These robust measuring cells are insensitive to shock and vibration and have a high resistance to overloads. They are used for pressure measurements from 600 mbar up to several thousand bar. with polysilicon stainless steel measuring cells: DMU 02, 02 Vario Benefits Robust measuring cell High resistance to chemicals No seal No internal transmission liquid High output signal High long-term stability Shock- and vibration-resistant 96 Division II

6 Technical information Measuring principle and measuring cell Piezo-resistive silicon measuring cells The function principle of piezo-resistive silicon measuring cells is based on a silicon chip with measuring resistors in the diaphragm. When pressure is applied and causes a deflection, the resistance changes. s opposed to open measuring cells which can only be used with certain, non-corrosive media, the silicon chips of encapsulated measuring cells are contained in a gas-evacuated protective housing filled with transmission liquid; this housing is closed with an elastic diaphragm at the pressure side. If the diaphragm is deflected as a result of the application of pressure, the transmission liquid is displaced towards the sensor. Silicon measuring cells are highly sensitive and have a high output signal. This allows for measurements at very low pressures and provides for high chemical resistance. with encapsulated silicon stainless steel measuring cells: DMU 0, 04, 05, 08,, 2, with open silicon measuring cells: DMU 0 D, 600/20 Benefits High resistance to chemicals High output signal Very small measuring ranges possible High accuracy Measuring principle and measuring cell Piezo-resistive and capacitance ceramic measuring cells luminium oxide (l 2O ) that is resistant to almost all chemicals is used for ceramic measuring cells. Piezo-resistive thick-film measuring cells consist of a base and a diaphragm made of aluminium oxide ceramic. During the production process, measuring resistors are burnt into the side of the diaphragm facing away from the medium; they change when pressure is applied to the diaphragm and causes a deflection. Ceramic thick-film measuring cells are used for medium pressure from bar to up to 400 bar. Capacitance ceramic measuring cells use a ceramic base and a ceramic diaphragm which are gold-coated on the side facing away from the pressure. The gold coating forms the electrode pair of a capacitor; they are positioned at a distance of just a few µm away from each other. Pressure causes a deflection of the diaphragm and the capacitance changes. Capacitance ceramic measuring cells are used for low pressures from 00 mbar to up to 60 bar; they have a high overload resistance. Both measuring cell types are mounted to the process connection via elastomer seals. The use of ceramic measuring cells is only limited by the chemical resistance of the seals. Different pressure loads and pressure measuring ranges can be obtained by varying the thickness of the diaphragm. with piezo-resistive thick-film ceramic measuring cells: DMU 0K, 0, 0 VM and DIM 20 with capacitance ceramic measuring cells: DMU 07, 09 Benefits Robust measuring cell High resistance to chemicals brasion-resistant No internal transmission liquid No chemical seal required Division II 97

50 Process engineering Pressure switches Differential pressure switches DS 0 Dimensions (mm) 48 Dimensions (mm) M 6 x Pipe Ø 6 pplication Description Suitable for all practically neutral media such as process water, heating water, neutral gases, oils. Suitable for two-point control by means of a continuously adjustable switching point (between 0 and 00% of pressure range). robust diaphragm type movement serves as the basis for this unit. It is suitable for overpressure, vacuum and differential pressure measurements. The unit uses the same principle of operation for all three measuring applications. The pressure or the differential pressure applies a force to one side of the diaphragm. This force displaces the diaphragm system and moves the measurement range spring. switching pin mounted to the diaphragm actuates an electrical switching element. The switching point is adjusted by means of a knurled knob according to the scale.
