Methane Detection Systems

MONITECH PORTABLE METHANE (CH4) GAS TESTING KIT

XP4 System is an intrinsically safe on-board machine mounted detection system for the monitoring of methane gas in hazardous areas (two methane channels) as well as water pressure and flow (two additional channels) in underground coal mines.
The XP4 incorporates the latest Intelligent Technology with (RS-485) communication capability.
Includes a full colour display unit for reading:
- Methane
- Water Flow and Pressure
- Oil Levels
- Oil Temperature
- Oil pressure variances (blockage detection)
Machine mounted applications include:
- Continuous Miner
- Roof Bolter
- Oil Level Gauge
- WiFi Container
Monitech XP4 System comprises of several unit components as follows:
- An approved control unit provides a continuous CH4 reading (0 -3%) and visual display. The alarm and trip set points are configurable according to customer specifications. A manual reset for the methane interlock is also available in the control unit using a dual key switch configuration.
Proven technology
Ease of Operation.
Robust Design.

Housed in a robust stainless steel enclosure complete with manual dual reset key switches
4–20mA Inputs/ 4x Digital Inputs.
Touch Screen Graphic Display.
Programmable Alarm / Trip Levels.
4xRelay Outputs.
CAN & RS485 Comms Available.

The Universal display, a configurable display controller used to monitor, display and log various inputs collected off machines. This information is then visible to the machine operator.
The display receives a 4-20mA output from the methane sensor and is processed to display a methane percentage reading.
The Display’s settings are password protected.
The Multi-Coloured 5” LCD Graphic display – is programmable into different alarm and trip indication values:
- - Green if the calibration is in order and no gas above alarm or trip levels is detected.
  - Yellow once the gas levels detected exceeds that of the alarm level, but still is not at the trip level.
  - Red once the gas levels reach the pre-set tripping value, to indicate a trip state. The display font also turns red when there is a fault in the methane system or when the calibration of the sensor is below -0.08%.
Monitor and Display serial interfaces (RS485, CANbus)
Accurate Real Time Clock (±5ppm or ±0.4 Second/ Day)
Log average data on non-volatile memory (Unlimited Read/Write Cycles)
May only be powered by Monitech Intrinsic Safe 24V PSU
