The chemical seal is intended to separate the pressure instrument from the pressure medium while allowing pressure variations to be precisely transmitted to the instrument's sensing element.

1 For Pressure Transmitters and Bourdon Tube Pressure Gauges Types 839 X Chemical Seals for Various Applications Advantages / Benefits Separation of medium and measuring device in difficult applications Application The Bürkert chemical seal system enables pressure gauges or pressure transducers and transmitters of varying designs to be adapted to the most adverse applications. The chemical seal is intended to separate the pressure instrument from the pressure medium while allowing pressure variations to be precisely transmitted to the instrument's sensing element. The pressure applied on the diaphragm of the chemical seal is transmitted to the pressure sensing element by means of a suitable liquid. Chemical seal body and diaphragm are generally made of stainless steel. In addition a wide selection of special materials is available to handle almost any fluid. Process pressures in a wide range can be handled and accurately measured, even at extreme temperatures and with corrosive or abrasive as well as highly viscous or contaminated process fluids. Undisturbed performance of the chemical seal under various process conditions requires careful evaluation of all process and environmental data. Chemical Seals are only available with a pressure instrument as a combined unit! Corrosive medium Highly viscous medium Non-homogenous medium Crystallizing medium High temperature medium (i.e. sterilization) Measuring application with hygienic cleanliness level (i.e. food applications) Toxic or polluted medium Burkert Contromatic USA 2602 McGaw Avenue Irvine, CA Tel Fax Bürkert Contromatic Inc. 760 Pacific Road, Unit 3 Oakville, Ontario, Canada L6L 6M5 Tel Fax Fluid Control Systems
