Nissha FIS Inc. Gas sensor module FIS3031-00NC-50 for LNG (methane)

FIS3031-00**-50 gas sensor module is a product that incorporates a semiconductor gas sensor into the control circuit. The drive control of gas sensor and output signal processing are performed by the microcomputer program.


  • High quality and high reliability: The mounted semiconductor SB-type gas sensor developed by our company features high sensitivity, quick response, and excellent durability
  • No need for calibration: The calibration with detection gas is already carried out at our factory. Therefore, you can use it as soon as the module is delivered to you
  • Easy installation in your device: Our module is compact, lightweight, and easy to take out the output signal. You can incorporate our module into your device easily
  • Can be used under severe environment/condition: You can choose module with or without case. Module with case has water-proof function, so that you can use under severe environment e.g. outside, inside of refrigerator etc.
  • Various output specifications:
    • Alarm output:1 or 2 point(s) can be set.
    • Concentration output is included within serial signal
    • Malfunction output:Sensor failure, circuit failure, various gas or silicone poisoning can be detected.
