Descriptions
The Hengesbach KS050D pressure transmitters is suitable for measuring the pressure and filling level in tanks and pipes. Its capacitative measurement cell and ceramic membrane makes the KS050D the ideal candidate for use in applications with abrasive media. KERAMESS pressure transmitters are designed for a measuring range of -1/0…1bar to -1/0…70bar. Special measuring ranges are also available.
The Hengesbach 050D series pressure transmitters are equipped with a micro-processor controlled electronics system and an accuracy of ≤ ± 0.2% FS. They are parametrised with a simple and user-friendly operating concept via 2 keys and a multi-colour status LED.
A Turn Down of up to 4 can be set using the full and empty adjustment. The large range of hygienic process connections such as e.g. the VARIVENT®, clamp DIN 32676, conical coupling with DIN 11851 groove union nut etc. guarantee the Hengesbach KS050D a variety of applications in the food industry and all other hygienic applications. A wide variety of process connections are also available for non-hygiene applications.
Their use in hygienic applications are assisted by the robust stainless steel field housing in the IP 67 and IP 69K, which withstands extremely aggressive cleaning techniques. The Hengesbach 050D pressure transmitters are highly-suited to use in applications which strict hygiene standards and basic requirements of functionality and accuracy
