Endress+Hauser Ceraphant PTC & PTP Pressure Switches

Endress+Hauser Ceraphant PTC31B / PTP31B / PTP33B Pressure Switches monitor absolute and gauge pressures in gases, vapors, liquids, and dust with a digital display and LEDs for onsite function checks and information. These cost-effective pressure switches provide high reproducibility and long-term stability and can be used internationally thanks to a broad range of approvals and process connections. The product lineup includes the PTP31B with a welded metal sensor diaphragm and small flush-mounted process connections. The PTC31B switches feature an oil-free ceramic sensor diaphragm and thread process connections. The PTP33B series is designed for hygienic applications and offers a fully welded metal sensor diaphragm, small flush-mounted hygienic process connections, and suitability for CIP/SIP cleaning.

All versions of these Endress+Hauser Ceraphant pressure switches feature customized measuring ranges, integrated switching electronics, and a housing and process-isolating diaphragm made of 316L stainless steel. Options include an IO-Link option for easy configuration and flexible integration in all fieldbus systems.
