Figure 2: 61-0140RK-05 LEL Detector Component Location
The combustible gas detector is a catalytic type detector that produces an electrical output
that corresponds to the detection range. It is packaged in a 1/2 inch NPT nipple with a
sintered metal flame arrestor on one end allowing ambient air to diffuse into the detector.
The flame arrestor also contains any sparks which may occur within the detector. The 1/2
inch NPT mounting threads at the top of the detector allow you to install it in the bottom
conduit hub of the junction box with the use of a 3/4 in. x 1/2 in. NPT reducer. A flame
arrestor guard is located at the bottom of the detector and is permanently bonded to the
detector housing. The flame arrestor guard protects the flame arrestor from impact
damage. Four color-coded leads extend from the top of the detector. The leads allow you
to connect the detector to the terminal block.
