1 Intelligent Electronic Pressure Switch in Hygienic Stainless Steel Ball Housing Description The electronic pressure switch is the successful combination of hygienic process connections with flush welded stainless steel diaphragm up to independent contacts, configurable optionally: - analogue output - Ex-protection (for -wire) nominal pressure range from mbar up to bar intelligent pressure switch digital display and has been developed for process industry; especially for food industry and pharmacy. Besides the is suitable for applications with high requirements on hygienic process connections and a rugged housing which is easy to clean. As standard the offers a PNP contact and is optionally available with a second, independent contact. Additionally the device could be equipped with an analogue output. The -wire version is also available with Exprotection. Operating The display module, which is mounted rotatable in the ball housing, shows the system pressure and allows programming. The configuration is menu controlled and easy to handle without previous knowledge. Applications process industry food industry pharmacy Characteristics indication of measured values on a -digit LED display rotatable and configurable display module configurable contacts (switch on / switch off points, hysteresis / window mode, switch on / switch off delay) option analogue output: - -wire version:... 0 ma or V with turn-down :6 - -wire version:... 0 ma Ex-protection optionally special functions (access protection, min. / max. value memory) industrial standard in view of accuracy, thermal behaviour and long term stability
