Product Specification

FSM-T-01 Pre-calibrated Module for Methane Gas

Features:

Gas concentration is digitally and quantitively output by means of communications
Alarm output can be set through programming
Factory calibrated, temperature compensated
Compact size, low cost

Applications

Front-end solution for methane gas alarm
Simple methane gas alarm output

FSM-T-01 is a pre-calibrated module for methane gas alarm which applies TGS2611 sensor together with optimized classic circuit measuring methane gas concentration. The module is pre-calibrated by Figaro's highly accurate calibration equipment and manufactured with mature aging process. The purpose of the module design is to save the development and production cost of the user to its greatest extent, making it easier and more convenient for them to manufacture gas alarm for civil natural gas.

The module is designed with two different interfaces considering the convenience for use. TTL level’s asynchronous communication interface allows the user to read real time gas concentrations with very simple commands;also different alarm thresholds can be set through communication programming. When the gas concentration reaches set value alarm output signal would be generated automatically from the alarm terminal.

Besides , this compact sized module applies a socket type design which facilitates regular replacements of the sensors. For some main board, different modules can also be replaced simply by plugging and pulling out, fulfilling the functions of detection and alarming for methane and other gases.
