Tensensor's TX981-A43 mining laser methane gas sensor utilizes TDLAS (Tunable Laser Absorption Spectroscopy) technology and is specifically designed for underground coal mine gas monitoring. It can continuously monitor methane concentration in the air 24 hours a day, offering advantages such as high precision, high stability, calibration-free operation, and interference resistance. It is the preferred professional equipment for mine safety monitoring.

    Key Product Features

    Superior Detection Performance: Fast response time (<15s); measurement range 0-5.00% VOL, resolution up to 0.01% VOL, accurately capturing minute changes in methane concentration.

    Stable Measurement Accuracy: Strictly controllable indication error: ±0.06% VOL in the 0.05% VOL-1.00% VOL range; ±6% of the true value in the 1.00% VOL-5.00% VOL range; accurate and reliable detection under normal temperature conditions.

    Calibration-Free with Zero Drift: Zero drift throughout the entire lifespan, eliminating the need for manual calibration and significantly reducing maintenance and calibration costs.

    Strong Intrinsic Anti-Interference Capability: Laser spectroscopy is specifically designed for methane identification; it is unresponsive to water vapor, dust, and other non-flammable non-target gases, preventing cross-interference and eliminating false alarms.

    Extra-Long Service Life: Designed for a service life of over 5 years, far superior to traditional catalytic combustion methane sensors.

    Advantages in Adaptability to Various Operating Conditions

    Wide Temperature and Humidity Adaptability

    Operating temperature: -10℃～50℃; Storage temperature: -40℃～85℃; Operating humidity: 0～95% RH (non-condensing), suitable for complex underground environments with high humidity and large temperature differences.

    Wide Pressure Adaptability

    Supports operating pressures from 86kPa to 106kPa, ensuring stable operation in various mine pressure environments.

    Rugged and Durable Housing

    Uses a 304 stainless steel housing, resistant to corrosion, impact, and wear and tear from harsh underground working conditions.

    Low Power Consumption Operation

Average operating current at room temperature: 50mA; Instantaneous operating current: 145mA, suitable for low-power power supply systems in mines.

    We understand that there is no room for compromise when it comes to mine safety equipment. Tensensor has achieved independent research and development and production of lasers, detectors, and sensor modules. This confidence in self-developed technology and commitment to full-chain self-control ultimately translates into accurate identification of methane concentration, providing a reliable guarantee for the safe, efficient, and intelligent operation of coal mines.
