Detcon Model Series 700 Gas Detection Sensors



"Environmentally Bulletproof"
• Water-Proof
• Corrosion-Proof
• Vibration-Proof
• Multi-Layer Surge Protection
• Pre-emptive Fault Diagnostics


Detcon Model Series 700 industrial gas detection sensors are a new generation of intelligent sensor modules that incorporate and integrate several leading edge improvements. The sensors are specifically designed for harsh and extreme locations. This new and superior level of environmental durability in sensor design includes an electropolished 316 stainless steel housing, multi-layered transient spike protection circuitry and 100% encapsulated electronics. The sensor electronics are completely protected and immune to water ingress and corrosion. The gas detector sensor elements are all plug-in components and can easily be replaced in the field. Operator interface is non-intrusive via a small handheld magnet. Configuration and routine calibration is intuitive and menu driven with fully scripted instructions. Sensor status is displayed on a built-in alphanumeric LED display. Model Series 700 intelligent sensor modules feature dual redundant outputs, a linear 4-20 milliamp analog signal and a Modbus RS-485 serial output.

Detcon Model 100 Gas Detection Sensors

"Simple, Affordable, Durable"

• 2-Wire Loop Powered
• Wide Range of Toxic Sensors + Oxygen
• XP-Intrinsically Safe design
• Non-Intrusive Interface
• 4-20 Milliamp Output
• Class I, Division 1, Groups B,C,D
• Integral Sensor Fault Diagnostics
• Fully encapsulated electronics


Detcon Model 100 Series sensors feature intelligent electronics, non-intrusive operator interface and comprehensive fault diagnostics. The sensor is packaged in an electro-polished 316 stainless steel housing fitted with a ¾ inch NPT thread. The plug-in, field replaceable sensor features large surface area gold-plated pins that reduce the effects of corrosion in harsh industrial environments. Signal conditioning electronics are completely encapsulated in the sensor housing adding a high level of durability to the design. The packaging is Explosion Proof (Class I, Div. 1 Groups B, C, D). Model 100 is equiped with a standard analog 4-20 mA current signal equivalent to the sensor range of detection. Upper enclosure options are aluminum and stainless steel (includes a transient protection terminal board). Additional accessories include wireless communications, a loop powered digital display, Remote Alarm Module (RAM), HART, and a current to RS-485 converter. The standard serial converter is Modbus RTU. Each sensor is shipped with a splash guard with integral calibration port.

Model DM-100 provides a wide range of toxic gas sensors and oxygen that uses electrochemical technology.

MultiFlame Flame Detectors

• Continuous auto-check of optical lens
• Selectable sensitivity and time delays
• Wireless detector configuration and testing using TLU
• HART® output option available

Two Models to Choose From
• DF-TV7-T: Multi-spectrum IR Flame Detector (3 wavelengths)
• DF-TV7-V: Multi-spectrum UV/2IR Flame Detector (UV + dual IR)

The MultiFlame DF-TV7-T is a multi-spectrum infrared flame detector using three wavelengths to respond to hydrocarbon fires and is the right choice for operation in dirty environments or for detection of smoky fires.The MultiFlame DF-TV7-V is a combined ultraviolet/infrared flame detector offering excellent long range detection. Both maintain outstanding false alarm immunity, are suitable for use in SIL2 applications and are configurable using a hazardous area approved wireless hand held terminal (TLU).

GD1 Laser Open Path H2S Gas Detector

Fastest Possible Speed of Response

• No sensor recalibration or replacement
• Superior detector stability and specificity
• Suitable for use in SIL 2 systems


The GD1 sets a new standard for toxic gas detection. Using a tuneable laser diode the GD1 delivers enhanced coverage and fail safe detection. The performance improvement marks a genuine step change for safety systems and life cycle cost savings. At the heart of the detector is a tuneable laser diode that eliminates environmental effects from sun, rain and fog. The laser scans single absorption lines where there is no interference from other gases. Unlike traditional methods for detecting H2S (MOS or EC cell) the GD1 needs no recalibration and can replace multiple standard detectors to cover the same risk.
