Product Description
PR 2255B2 Loop-powered HART Temperature Transmitter
The PR 2255B2 is a versatile 2-wire loop-powered HART 7 temperature transmitter designed for converting various input signals, including RTD, thermocouple (TC), Ohm, or millivolt (mV), into a scalable 4…20 mA analog output signal. Specifically engineered for DIN form B sensor head mounting, the PR 2255B2 allows for easy configuration and monitoring through HART communication. It can be pre-configured to meet specific application requirements. Built to stringent safety standards, this transmitter is suitable for use in SIL 2/3 installations and holds certifications for ATEX, IECEx, FM, CSA, and InMetro hazardous area applications.
