Oxygen Analyzers with Remote Sensor (GPR-x900)
Panel/wall analyzers with remote sensor head for flexible installation.
Key Features
- Measurement ranges from 0–10 ppm to 0–100 %
- Remote sensor for in-line and extractive applications
- Temperature compensation
- Two user-configurable alarms plus power-failure relay
- XLT sensor options for CO2 backgrounds
- LCD with four-button interface
- Panel mounting
Overview
GPR-1900 (ppm) and GPR-2900 (%) are cost-effective, reliable and compact panel-mounted oxygen analyzers with a remote sensor that can be located near or inside the process. They feature two configurable alarms and an LCD screen with a four-button interface; the XLT sensor enables measurement where more than 0.5 % CO2 is present.
Working Principle
A remote electrochemical oxygen sensor (GPR-12-333 / XLT-12-333 for ppm; GPR-11-60-4 / XLT-11-24-4 for %) is installed in-line or extractively, with temperature compensation. The panel analyzer provides a 4–20 mA or 1–5 V output, range ID signal and three relays (two setpoint alarms, one power-failure alarm).
