The MIR combustible gas detector uses an infra-red (IR) light beam to detect and accurately measure methane gas concentration, while continuously performing self checks.
Detector Electronics (Det-Tronics) has released a new Mining IR (MIR) fixed methane gas detector approved by the US Mine Safety and Health Administration (MSHA).
Intended for installation in underground mines, the MIR combustible gas detector uses an infra-red (IR) light beam to detect and accurately measure methane gas concentration, while continuously performing self checks so there are no unrevealed failures.
Det-Tronics is part of UTC Fire and Security, a unit of United Technologies.
"In support of the mining industry's commitment to total safety, we developed a fixed methane gas detector that remains sensitive and accurate even after prolonged exposure to oxygen-depleted environments and in areas with high levels of hydrocarbon gas", said Mike Bragg, Det-Tronics Product Manager.
Benefits include reduced calibration and maintenance requirements, long life and low cost of ownership.
For ease of installation, the MIR is factory-calibrated and is shipped ready to install with pre-fitted MSHA-approved cable glands.
To reduce maintenance, the detector's modular design provides field-replaceable optics-protection filters.
In addition, the transmitter display module provides an easy to read digital LCD readout indicating 0-5% by volume detected gas concentration.
The MIR easily integrates into new or existing systems via the standard 4 to 20mA analogue output and optional alarm/fault relay-output package.
