Product Details<\/h2>\n

Laser methane (CH4) detection with two product options. Please select the required version before ordering.<\/p>\n

<\/p>\n

OPTIONS<\/p>\n

1. 5V TTL Sensor Module: sensor module for integration with a compatible controller.<\/p>\n

2. LED Gas Alarm: complete methane gas alarm with LED concentration display and audible\/visual warning.<\/p>\n

<\/p>\n

SENSOR MODULE SPECIFICATIONS<\/p>\n

Target gas: Methane (CH4)<\/p>\n

Detection: Laser absorption, diffusion sampling<\/p>\n

Measuring range: 0-100% Vol<\/p>\n

Power supply: 5V DC<\/p>\n

Output: TTL UART serial interface<\/p>\n

Housing: 304 stainless steel<\/p>\n

Accuracy at 0-1% Vol: +\/-0.05% Vol<\/p>\n

Accuracy above 1% Vol: +\/-5% of the reading<\/p>\n

Resolution: 0.01%<\/p>\n

Response time: less than 50 seconds; typical 30 seconds<\/p>\n

Operating temperature: -10 to +50 C<\/p>\n

Relative humidity: less than 98% at +25 C<\/p>\n

Operating pressure: 30-150 kPa<\/p>\n

Dimensions: 68 mm total height; 35 mm base diameter<\/p>\n

<\/p>\n

The module and complete alarm are separate purchase options. The 5V supply and TTL output specifications apply to the sensor module. The complete alarm has its own wiring and interface requirements.<\/p>\n

<\/p>\n

Confirm the pin assignment and UART logic level before connecting the sensor module. Do not connect the TTL interface directly to RS232 or RS485. %Vol and %LEL are different concentration units. Follow the supplied installation and calibration instructions.<\/p>\n<\/section>\n
