These high-quality pressure switches have been specifically developed for applications with limited space in hazardous zones.
High quality and product manufacturing to ISO 9001:2000 ensures reliable monitoring of your plant. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested.
All wetted parts materials are from Hastelloy® C276 or stainless steel as standard. Each switch family is available in IP 66, Ex-ia or Ex-d versions (Ex-ia see model PXS, data sheet PV 34.36).

In order to ensure as flexible operation as possible, the pressure switches are equipped with micro switches, which make it possible to switch an electrical load of up to 5 A / AC 220 V directly. For smaller contact ratings, such as for PLC applications, hermetically sealed micro switches with gold-plated contacts can be selected as an option.
By using a disc spring with a prestressed snap-action spiral tube the pressure switch model PXA is extremely reliable and guarantees optimal operating characteristics.
