Cubic Innovative Ultra-Low Power Miniature NDIR Methane Sensor for Portable Gas Detectors

Contents

In high-risk operation scenarios in the fields of oil and gas, coal mining, and urban underground engineering, methane, as a flammable and explosive gas will pose a great threat to personnel safety and equipment operation once leaked. To ensure operation safety, portable methane gas detector is becoming an important and practical tool for front-line personnel because of its lightness, flexibility, and rapid response. However, the application of portable gas detectors is always influenced by battery power, response speed, and long-term reliability.

 

To meet the application requirements of portable methane gas detectors, Cubic, as a leading manufacturer of gas sensors and gas analyzers, has launched the ultra-low power miniature NDIR methane sensor, SJH-5BUL, to provide a more reliable, stable and faster CH4 detection solution for the market.

 

Cubic SJH-5BUL is developed based on advanced non-dispersive infrared (NDIR) technology, and adopts dual-beam design, to realize effective low power consumption while achieving accurate detection. It is very suitable for integration into various battery-powered portable gas detectors or transportable gas detectors, outdoor solar-powered IoT devices and other low-power based wireless monitors. Cubic SJH-5BUL also features fast response, providing timely alarm for methane leaks.

 

Cubic SJH-5BUL follows standard industrial 4-series appearance design, with a compact size for easy integration. It can accurately detect methane concentration with a range of up to 100% LEL, and supports real-time concentration monitoring in complex working conditions such as high humidity, high dust, and strong vibration, reducing false alarms and missed alarms. Its excellent power consumption performance can significantly extend the battery life of the portable gas detectors and reduce the frequency of battery replacement or recharging. Cubic miniature NDIR methane sensor is particularly suitable for handheld gas detectors for oil and gas industry inspectors, wearable alarm devices in mine operations, or mobile devices for urban gas maintenance.

 

Key features highlight:

  • Dual-beam NDIR technology

  • Average working current less than 1mA

  • Superior fast T90 time < 15s

  • Linearization and factory calibration for accurate digital output

  • Matrix calibration to ensure high accuracy over full-temperature

  • Embedded temperature and humidity compensation

  • Long lifespan over 10 years

  • Ex-proof grade Ex ia II C T4 Ga


With these features, Cubic ultra-low power miniature NDIR methane sensor, SJH-5BUL can be widely applied for multiple scenarios including oil and gas extraction, LNG transportation, coal mining, natural gas pipelines networks, and industrial plants, to provide a more reliable, stable and faster CH4 detection solution.
