GG-LEL2-C4H10 CTI Gas Sensor N-butane 0-100% LEL 4-20 mA Output, Explosion Proof Housing

The GG-LEL2 utilizes catalytic-bead sensor technology with a matched pair of detector elements. When combustible vapors enter the sensor, the passive bead remains unchanged while the active detector bead catalyzes the oxidation of gas, generating heat and changing its resistance. The resulting change in resistance is accurately measured across the bridge circuit.

Key Features:

• Useful for activation of electrical shunt-trip, ventilation, or fuel supply shutoff
• Industry standard linear 4/20 mA output
• Calibrated for desired combustible gas 0-100% LEL (specify target gas)
• Sensing element designed for long life in harsh industrial environments
• Class l, Div 1, Groups B, C, and D explosion-proof housing
• Designed to perform in temperatures of -40°F to +140°F
• Real-time continuous monitoring
