FP-524HT

Detcon Model FP-524HT sensors are non-intrusive “Smart” sensors designed to detect and monitor combustible gas in air over the range of 0-100% LEL (lower explosive limit).

The sensor assembly consists of a matched-pair catalytic bead sensor in a stainless steel housing that includes a splashguard with integral cal port, a plug-in control transmitter circuit, a base connector board and an explosion proof enclosure.

This sensor assembly is specifically designed for high temperature applications wherein the sensor can be mounted in high temperature areas while the transmitter is installed outside the area using a sensor separation kit.

  • High Temperature sensor head rated for 150°C operation

  • Simple menu driven calibration - takes less than 3 minutes

  • LED display and LED indicators for FAULT, ALARM 1, ALARM 2 and CAL status

  • Plug-in field-replaceable transmitter and sensor

  • Long sensor life expectancy: averaging longer than five years in harsh offshore drilling/production environment

  • 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)
