Molecular Property Spectrometer (LEL-MPS)
An overview of the LEL-MPS sensor.
The LEL-MPS is a solid-state sensor used to detect combustible gases. It classifies gases based on their molecular properties and does not require routine span calibration. It is not intended for inert environments. Sensor accuracy decreases significantly below 18% oxygen. Use is not recommended when O₂ levels are under 10%.
LEL sensors cannot be disabled in Blackline Live.
LEL-MPS Sensor Automatic Zeroing at Startup
LEL-MPS sensors must be zeroed in clean air to function properly. Sensors automatically zero at startup. For LEL-MPS, your Blackline Live administrator can enable an optional Clean Air Startup prompt in Blackline Live (default: disabled). Other sensors automatically zero at startup and do not display a prompt.
For more information on manual zeroing, see Zeroing G8.
LEL-MPS Sensor Calibration
You can calibrate your LEL-MPS sensor in two ways:
Default calibration: The default calibration process validates and ensures accuracy without adjusting the LEL-MPS sensor's readings. Unlike traditional sensors, this sensor is factory-calibrated for optimal accuracy.
Blackline Safety recommends using the factory calibration for the lifetime of the sensor.
Full calibration: Advanced users can enable span adjustment in Blackline Live to perform a full calibration on the LEL-MPS sensor. This may negatively affect the sensor's ability to accurately detect other combustible gases. Blackline recommends using the factory calibration for the lifetime of the sensor.
Contact Technical Support before performing a manual calibration.
