MM-2PW
A methanometer is an essential device for measuring methane concentration in the air, particularly in the gas and mining industries, where monitoring methane levels is vital for safety. Methanometers are equipped with detectors that allow for precise measurement of even small amounts of methane, enabling quick responses in potentially hazardous situations.
Description
The MM-2PW methanometer is designed for continuous methane concentration monitoring within the range of 0-100% CH4. It is tailored for measurement of methane concentration:
– In mining atmospheres (MM-2PW model)
– In pipelines (MM-2PW/A model)
Features
– Continuous measurement of methane concentration in the atmosphere or pipeline
– Display of measurement results and output status, with communication to the surface station via a telemetry line
– Alarm signaling for exceeding set threshold levels
– Support for two-state input and output systems
– Self-diagnostics of the methanometer and display of emergency statuses
Specification
Power Supply: 60 V, 40 mA DC from the telemetry central or from the intrinsic safety power supply.
Minimum Power Supply Parameters: 30 V, 40 mA DC.
Battery Autonomy: Minimum 8 hours.
Maximum Cable Length: 30 m for CKM/W connecting the methanometer to the measurement head.
Measurement Type: Continuous in the range of 0-100% CH4.
Advantages
Precise Measurement: Vital for safety in mines and industrial process management.
Display of Measurement Results: A clear display that shows the current methane concentration.
Display of Output Status: Information about the status of outputs like alarm indicators or relays allows operators to monitor and respond to environmental changes.
Telemetry Communication: Communication with the surface station via a telemetry line allows for remote monitoring and control, crucial for mining environments and extensive pipelines.
Alarm Threshold Exceedance Signaling: Alerts operators immediately when set alarm thresholds are exceeded, enabling quick reactions to potentially dangerous situations.
Support for Two-State Input and Output Systems: Integration with various monitoring and control systems is facilitated.
Self-Diagnostics: Continuous monitoring of the device’s status and detection of possible faults or issues in real-time.
Emergency Status Display: Provides operators with information on emergency statuses such as measurement errors, communication disruptions, or power issues.
Ex Zone
The device is designed to operate in explosive atmospheres. It is suitable for underground use in mines and surface areas of mines at risk of gas or dust explosions. Group I, Category M1 – designed for mining facilities exposed to methane and coal dust hazards, ensuring a very high level of safety with two independent safety measures.
