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.
