Continuously measures oxygen concentration in gaseous mixtures, including suitable flammable-gas applications.
Key Information
MG8E-5AWNS-E is a flameproof Yokogawa paramagnetic oxygen analyzer with integrated detector and converter. Its magnetic proportional-flow method measures oxygen selectively without exposing the sensor directly to the sample gas.
The suffix identifies a 0-5 to 0-25 vol% O2 range execution, standard cell material, nitrogen auxiliary gas at 35 ml/min, 100-115 VAC power and English language configuration.
Functions
Provides an isolated 4-20 mA analog output plus configurable status, alarm and range contacts.
Supports remote range change and calibration-start contact inputs.
Offers automatic, semiautomatic or manual calibration with self-diagnostics and atmospheric-pressure compensation.

Installation
- Handle the analyzer as a 38 kg precision instrument and protect it from impact during unpacking and mounting.
- Install indoors on the approved panel or wall arrangement and use the specified flameproof cable glands.
- Supply nitrogen auxiliary gas at 350-500 kPa before applying electrical power.
- Condition the sample to the specified flow, pressure and temperature and vent it safely to atmosphere.
- Prove zero with nitrogen and span with dry air, then verify analog and contact behavior before service.
Lifecycle
- Retain the full MG8E-5AWNS-E suffix because range, cell, gas, flow, power and language are coded in the model.
- Maintain clean sample conditioning and stable auxiliary-gas pressure to protect measurement performance.
- Archive calibration results, interference-gas compensation settings and alarm assignments after each service event.

FAQ
What must be supplied continuously for MG8E-5AWNS-E operation?
The analyzer requires the specified nitrogen auxiliary gas; it must be flowing at the required pressure before electrical power is applied.
Can MG8E-5AWNS-E be replaced by another MG8E suffix?
Only after every suffix field is compared. Range, cell material, auxiliary-gas condition, power and language are configuration-defining items.
What process information is needed before installing MG8E-5AWNS-E?
Provide sample composition, expected oxygen range, temperature, pressure, moisture, contaminants and the proposed sampling and vent arrangement.
What should be included in an MG8E-5AWNS-E calibration record?
Record zero and span gases, gas pressures and flow, ambient conditions, response, analog output and any interference-gas compensation adjustment.
How should MG8E-5AWNS-E be handled during maintenance?
Use suitable lifting support, preserve flameproof joints and glands, isolate power and gases, and prevent shock to the precision measuring assembly.
