140B Methane Monitor
- Consistent and reliable performance
- Rock solid design keeps you operating safely
- MSHA Approved
Tried and trusted, the 140B Methane Monitor has become an essential tool to keep production running, and running safely. The 140B can be mounted on mining machinery such as continuous miners, roof bolters, longwall shearers, or other machinery that may come in contact with methane pockets.
By shutting down machinery at customizable alarm settings, and restoring machine power once methane concentrations fall below the allowable setpoint, the 140B reduces downtime while keeping your operation safe.

The 140B Control Unit contains the "brains" of the methane monitor system. It communicates with the 140B Detector to display methane concentrations on a large, bright, easy-to-read display and sends appropriate relay signals to the power supply when alarm or shutdown thresholds are reached. An infrared remote calibrator is available to make calibration a quick and easy task.

The 140B Power Supply interfaces directly with machine power and converts it to be used by the 140B Detector and 140B Control Unit. It contains 2 relays, one of which can be tied to a warning signal when methane concentrations are rising (such as a warning run light) and one that shuts down the machinery when the allowable methane concentration threshold is reached. The 140B Power Supply Chassis is housed in an explosion proof box to maintain the highest degree of safety.
