Detcon Model FP-624D is a “Smart” gas detection sensor designed to detect and
monitor combustible gas in 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 back more than 20 years. The sensor
assembly includes the detector in stainless steel housing, a base connector board,
an explosion proof enclosure (available in aluminum or stainless steel), a plug-in
control transmitter circuit, and a splashguard with integral cal port. The packaging
is Explosion Proof (Class I, Division 1, Groups C & D).
Model FP-624D is equiped with a standard analog 4-20 mA current signal
equivalent to the sensor range of detection, RS-485 serial communications port, 3
alarm relays, one-man 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.
