Teledyne FP-624D Combustible Gas Sensor

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, nonintrusiveoperator 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,
2 alarm relays and 1 fault relay, 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
