1.4 Plug-in Replaceable Sensor
The Detcon combustible gas sensor is a poison-resistant and field proven design. It is packaged as true plug-in
replaceable type sensor with over-sized gold-plated connections that eliminate corrosion problems. It can be
accessed and replaced in the field very easily by releasing the locking screw and unthreading the housing bottom.
The Detcon combustible gas sensor has an infinite shelf life, and is supported by a 2-year warranty. The expected
service life is 3-5 years.
