for the detection of Methane and LP Gas - TGS 2612

Product Specification

Features:

* Low power consumption
* Similar sensitivity at same %LEL levels for both methane and LP gas
* Long life and low cost
* Uses simple electrical circuit

Applications:
* Residential LNG and LPG alarms
* Portable combustible gas leak detectors
* Detectors for LNG and LPG

The sensing element is comprised of a metal oxide semiconductor layer
formed on an alumina substrate of a sensing chip together with an integrated
heater. In the presence of a detectable gas, the sensor's conductivity increases
depending on the gas concentration in the air. A simple electrical circuit can
convert the change in conductivity to an output signal which corresponds to
the gas concentration.
The TGS 2612 has high sensitivity to methane, propane and butane, making it
ideal for LNG and LPG monitoring. Due to its low sensitivity to alcohol vapors
(a typical interference gas in the residential environment), the sensor is ideal
for consumer market gas alarms.
Due to miniaturization of the sensing chip, TGS 2612 requires a heater current
of only 56mA and the device is housed in a standard TO-5 package.
