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 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 & 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.
Features
- Performance Certified to CSA 152 cCSAus for Class I, Division 1, Groups C & D.
- Transmitter design fits all existing Detcon Catalytic Bead Sensors dating back 20 years.
- Compatible with PLCs, SCADA, DCS, via 4-20 mA, and/or RS485, and/or alarm relays.
- Sensor status and parameters are accessible via RS-485 (Modbus).
- Menu programmable relays standard (two alarms plus fault).
- Simple menu-driven calibration – less than 3 minutes.
- LED display with LED indicators for FAULT and CAL status.
- Plug-in field-replaceable transmitter.
- Long sensor life: averaging +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.
Applications
- Oil and Gas Drilling Rigs
- Oil and Gas Production Sites
- Offshore Production Platforms
- FPSOs
- LNG/CNG Plants
- Refining and Petrochemical
