Rosemount 1151 Transmitter

Core Performance & Industrial Application

The Rosemount 1151 analog pressure transmitter converts measured pressure to a 4-20 mA DC signal for legacy panel and DCS loops.

Nameplate calibrated range: 12.5 to 250 kg/cm²; maximum working pressure 6000 psi; sensor material 316L SST.

Two-wire analog output; supply up to 45 VDC maximum; explosion-proof Ex d IIB T4/T6 housing per ATEX 0087.

The modular 1151 mechanical/electronic design allows interchangeable parts across the installed base.

It is used as spare replacement on older Rosemount 1151 pressure and DP measurement loops.
