The GG-LEL2 utilizes catalytic-bead sensor technology with a matched pair of detector elements. When combustible 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.
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 ¾” 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.
