GPR-x500 Trace & Percent Oxygen Transmitters

Loop-powered online oxygen transmitters for ppm (GPR-1500) and percent (GPR-2500) process measurement.

ModelGPR-1500 / GPR-2500
SKUAI-GPR1500GPR2500
CategoryOxygen & Combustion Analyzers

Key Features

  • Measurement ranges from 0–10 ppm to 0–25 %
  • Sensor options for He, CO2 or H2 gases
  • Hazardous-area rated (ATEX/IECEx Ex ia IIC T4 Ga, cMETus)
  • Gas temperature compensation
  • Loop-powered 4–20 mA configuration
  • Customized sample systems available

Overview

GPR-x500 analyzers are single-channel loop-powered oxygen transmitters engineered for trace oxygen analysis (GPR-1500) and percentage measurement (GPR-2500) in clean gas. Sensor options extend measurement to gases such as carbon dioxide, helium and hydrogen, and versions are available for safe and hazardous areas.

Working Principle

An electrochemical oxygen sensor (GPR-12-333 / XLT-12-333 for ppm; GPR-11-60 / XLT-11-24 for %) measures the sample with gas temperature compensation, and the 18–24 V DC loop-powered electronics provide a 4–20 mA output.

Benefits

  • Low 1.8 W power consumption
  • Safe-area and hazardous-area versions
  • Up to 60-month sensor life (GPR-11-60, in air)
