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

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.

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.

Applications

Mechanical Rooms
Tank Rooms
Pulp and Paper
Refineries
Boiler Rooms
Refrigeration Systems
Chemical Plants
Maintenance Garages
Heat Treatment
Cold Storage
Breweries
Process Areas

Benefits

Low cost explosion protection
Long sensor life (5-7 yrs typical)
Simple operation & calibration

The GG-LEL2 is designed to detect and monitor potentially explosive levels of combustible gas vapors in air within the range of 0-100% LEL.

A 3⁄4� NPT threaded conduit entrance is provided on the top of the transmitter housing. Mounting tabs are provided for support of the GG-LEL2. Long sensor life can be expected in most mechanical room applications with a typical sensor life of 5-8 years. Field replaceable sensor element keeps long term maintenance simple and low cost.
