Features

  • Pre-calibrated sensor easily connects to a Rosemount 925 gas transmitter and can be factory calibrated to butane gas, propane gas, methane gas, ethylene gas or ethane gas
  • Gas sensor can be calibrated off-site and installed later
  • Gas sensor retains own configuration settings and calibration information
  • Smart sensor module provides reduced maintenance costs and downtime with longer calibration intervals
  • When connected to a Rosemount 925 gas transmitter, the gas sensor continuously communicates digitally, providing stable, accurate protection with fast response times even over long separation distances
