The Detcon model FP-624D by Teledyne is a “Smart” gas detection sensor designed to detect and monitor combustible gas in the air over the range of 0-100% LEL (lower explosive limit) using matched-pair catalytic bead technology.
Model FP-624D features Detcon’s MicroSafeTM intelligent electronics, non-intrusive operator interface and comprehensive fault diagnostics. The sensor transmitter features an advanced universal design that fits all existing Detcon matched-pair catalytic bead sensors dating over 20 years. The sensor assembly includes the detector in a stainless steel housing, a base connector board, an explosion-proof enclosure (available in aluminium or stainless steel), a plug-in control transmitter circuit, and a splashguard with an integral cal port. The packaging is Explosion Proof (Class I, Division 1, Groups C & D).
Equipped with a standard analogue 4-20 mA current signal equivalent to the sensor range of detection, RS-485 serial communications port, two alarm relays and one fault relay, one-person remote calibration, self-adjusting zero and span, and LED indicators for fault, alarm, and calibration status. Detcon’s combustible gas sensor has an infinite shelf life and is supported by a 2-year warranty.
