Mounting to Bourdon tube pressure gauges pressure transmitters for indirect pressure measurement of media containing solid particles, e.g. in the paper mill industry. Often also used in the paint processing and other industries. The separator is inseparably fixed with the pressure measuring instrument to a hydraulic measuring unit; either directly, via a cooling element or via a capillary tube of stainless steel. Separation element concentrically corrugated and welded to the body; loose fixing flange. Connection for Haenni welding flange or appropriate measuring point. Temperature of medium Up to 80°C (1/2 h up to 140°C). Other temperature limits (up to 300°C) on request. Hydraulic transmission fluid Silicon oil (standard), others on request.
