Detcon FP-700 Combustible Gas Sensor

The Detcon FP-700 by Teledyne is a non-intrusive, “Smart” sensor designed to detect and monitor combustible gases in the air over the range of 0-100% LEL, utilising catalytic bead sensor technology. The plug-in, field-replaceable detector is poison-resistant and features oversized gold-plated connections that help prevent corrosion.

The FP-700’s rugged framework includes an electro-polished 316 stainless steel housing with fully encapsulated electronics and dual-layer surge protection. This innovative design virtually eliminates sensor failure due to water ingress, corrosion, vibration, and transient spikes.

A primary feature of the Model FP-700 is embedded intuitive software that simplifies the operator interface by guiding the user through routine calibration, configuration, and fault diagnostic functions using a built-in alpha/numeric display. The Model FP-700 is equipped with standard analogue 4-20mA and Modbus RS-485 outputs. Among its unique features is a wireless option that can be used with Detcon’s SmartWireless product line. Additional integration options include a Remote Alarm Module (RAM) and HART. Detcon’s combustible gas sensor has an infinite shelf life and a 2-year warranty.

Suitable for Oil and Gas, FPSOs, LNG/CNG Plants, Refining and Petrochemical, Pulp and Paper Mills and Waste Water Treatment Plants.
