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 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.


  • 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
