1.4 Intelligent Plug-in PID Gas Sensor
The Detcon range of PID gas sensors are field proven, intelligent plug-in sensors (one type is used for ranges
of 20ppm and less, another is used for ranges greater than 20ppm.) The Sensors employ 100% encapsulated
circuitry and over-sized gold-plated connections that eliminate corrosion problems. The intelligent design
provides automatic recognition of gas type, units, full-scale range, and calibrations data when a new sensor is
plugged in. The sensor can be accessed and replaced in the field very easily by releasing the locking setscrew
and unthreading the Splashguard Adapter. The PID Sensor cell can be disassembled so that the lamp used can
be cleaned or replaced. Detcon’s ranges of PID sensors has a long shelf life and are supported by an industry-
leading warranty.
