The GG-LEL2 sensor provides an industry standard linear 4/20 mA output signal proportional to 0-100% LEL of the target gas. The transmitter is compatible with most gas detection systems and PLCs. Long sensor life with minimal span adjustment can be expected in most applications. The sensor is designed for simple calibration and is field replaceable.Key Features:Useful for activation of electrical shunt-trip, ventilation, or fuel supply shutoffIndustry standard linear 4/20 mA outputCalibrated for desired combustible gas 0-100% LEL (specify target gas)Sensing element designed for long life in harsh industrial environmentsClass l, Div 1, Groups B, C, and D explosion-proof housingDesigned to perform in temperatures of -40°F to +140°FReal-time continuous monitoring
