OMD-625 Hazardous Area Oxygen Analyzer

Description

Description

The OMD-625 Hazardous Area Online Oxygen Analyzer is designed to measure oxygen from 0.01 parts-per-million up to 10,000 parts-per-million up to 100%.  The analyzer comes with ATEX and IECEx certification for use in Ex db ib IIB+H2 T4 Gb areas. The unit combines an advanced set of electronic features including a smart MENU interface with our industry leading precision electrochemical oxygen sensor technology. The result is a highly reliable and cost effective design with easy-to-use user interface.

  • Enclosure Type: Wall Mount; Pole Mount
  • Standard Ranges: 0 – 10/100/1000/10000 PPM & 25%
  • Optional Ranges: 0 – 1/5/10/25 & 100 %
  • Range Mode: Auto-Range or Manual Range
  • Resolution: 0.01 PPM or 0.01 %
  • Input Power: 100 – 240 VAC or 12 – 24 VDC
  • Analog Output: 4 – 20mA or 1 – 5V DC
  • Communication: Bi-Directional MODBUS RS485 RTU
  • Alarms: 2 Fully adjustable Form C relay contacts

The built in smart MENU interface allow the user to fully configure the analyzer through the onboard MENU system including a unique ability for the user to enter a custom range such as 0 – 2000 ppm or 0 – 734 ppm full scale.  No need for a complicated laptop or other control device to setup the analyzer in the field.

The analyzer is designed as an extractive type unit to draw the sample through its integrated sample system which includes a 3-way sample / span valve, and a visual rotameter / flowmeter with flow control valve.

The standard cell (TO2-133) is unaffected by other background gases such as hydrogen, helium, or hydrocarbons. The optional acidic cell (TO2-233) works well when acid gases such as CO2 or Natural Gas are present an H2S resistant sensor is also available as are sensors dedicated for percent oxygen measurement.  All oxygen sensors are manufactured in house by Southland Sensing Ltd. under a strict ISO9001:2015 / ISO13485:2016 quality system.

The sensors are self-contained and minimal maintenance is required – no need to clean electrodes or add electrolyte.

Primary applications for this analyzer include natural gas, landfill, hydrogen production and other industrial applications.
