Pneumatic Retractable Fittings hem Energy Pharm Food Water SensoGate W 3 Pneumatic retractable fitting for simple commercially available control units or process applications Variable and reasonably priced ased on the proven SensoGate modular design principle, the W 3 retractable fitting is ideal for applications which do not require completely automated control with central media routing but which still want to make use of superior SensoGate technology. SensoGate W 3 is ideal for automatic or semi-automatic connections to commercially available or customerdeveloped control units. Individual solutions The design of the affordable SensoGate W 3 models is scalable to meet requirements; when placing an order, customers simply state the types of connections and functions the retractable fitting must have. Every design permits the sensor to be manually serviced or replaced during the process. This can easily be done under process pressures as great as bars. The fitting adapts perfectly to the application and can even be adapted later to changed conditions. Easy retrofitting For example, if at some later point another media connection is necessary, this can be very easily arranged by the simple replacement of the relevant module. switch from metal to plastic or a switch to electrodes with a store of liquid electrolyte is possible one big advantage of the SensoGate modular design. The patented lock-gate function, i.e., the reliable shut-off to the process even during movement, is always active. This also applies to the hygienic version, which is a unique design feature in the world market for retractable fittings. Facts compact, smooth, and dirt-resistant design minimum maintenance costs and maximum flexibility thanks to completely modular design very simple replacement of gaskets due to divided calibration/cleaning chamber increased service life and reduced seal wear TEX approval II G c II for the complete fitting cost reduction by simple installation, operation, and maintenance very high availability protective rinsing of the seals for a long service life SensoLock for high safety of operation integrated check valves and limit switches fast and uncomplicated replacement of calibration chamber and immersion tube all maintenance can be performed on site cyclone rinsing for optimum cleaning effect superior sensor immersion depth standard sensor length (225 mm) even for large immersion depths multiple process connections available flange version with scraper ring modular design allows specific replacement of the process-wetted materials: PEEK, PVF, PP,.457, Hastelloy plastic versions with high pressure and temperature resistance due to carbonfiber-reinforced plastics special version for sensors with pressurizable liquid electrolyte 24
