Pressuresensor-EPT-CAN
Specification
The CANopen enabled EPT-CAN series pressure sensor provides high accuracy measurement of up to 2000 bar with over twenty standard
measurement ranges in a compact and robust stainless steel design. The CANopen protocol ensures straightforward industry standard
commissioning with interfacing to CAN 2.0A or optionally CAN 2.0B, and the 1Mbit/s data rate ensures fast update pressure measurement.
The fully welded stainless steel casing encloses an encapsulated thin-film sensor technology that does not rely upon a transmitting media
and, as a ‘dry’ measuring cell, is suited to applications where leakage would be problematical. The EPT-CAN has a generous overload and
burst pressure ratings that ensure maximum safety.

IPsystemofprotection
The IP system of protection as specified in the data sheets generally applies, with their mating plug connected. Relative pressure transmitters usually require a ventilated mating plug and/or cable to allow for pressure compensation. From a pressure range of 60 bar, a ventilated mating plug and/or cable is not necessarily required.
