Teledyne Detcon IR-700-CH Combustible Gas Sensor
The Teledyne IR-700 is a non-intrusive “Smart” sensor designed to detect and monitor combustible gases in air over the range of 0-100% LEL using catalytic bead sensor technology. The plug-in, field-replaceable detector is poison-resistant and features oversized gold-plated connections that help prevent corrosion. The IR-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 IR-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 IR-700 is equipped with standard analog 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 is supported by a 2-year warranty
