Detcon Model FP-524D Combustible Gas Detector
The Detcon model FP-524D by Teledyne is a “smart” gas detection sensor designed to detect and monitor combustible gas 0-100% LEL using matched-pair catalytic bead technology. Features MicroSafe 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 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 and D).
Equipped with a standard analogue 4-20 mA current signal equivalent to the sensor range of detection, one-person remote calibration, self-adjusting zero and span, and LED indicators for fault and calibration status. A HART communications option is also available. The combustible gas sensor has an infinite shelf life and is supported by a 2-year warranty.
Features
- Certified to ISA performance standards.
- cCSAus approved for Class I, Division 1, Groups C & D.
- Transmitter design fits all existing Detcon Catalytic Bead Sensors, dating back 20 years.
- Simple menu-driven calibration – less than 3 minutes.
- LED display and LED indicators for FAULT and CAL status.
- Plug-in field-replaceable transmitter.
- Extended sensor life: average +5 years in harsh offshore drilling/production environments.
- High resistance to poisons such as sulfides, chlorides, silicon-based contaminants, etc.
- Low power consumption (less than 3.5 watts versus 8+ watts on competitive brands).
- Extensive Fault diagnostics.
- Replaces model FP-524C.
