Spectrex SharpEye 20/20MI IR3

The Spectrex SharpEye 20/20MI is a triple IR (IR3) flame detector in a rugged stainless steel housing. Due to its compact size it is very useful in applications in small and tight areas, eg. windmills or turbine enclosures.

Flame Detector

  • Sensor: IR Sensor
  • Installation: non-explosion proof
  • Interface: RS-485, Relay
  • IP class: IP55
  • Special: Small and tight areas

Always keeping an eye on things

With its extensive optical range and high immunity to false alarms, the SharpEye 20/20MI IR3 compact mini flame detector provides reliable area monitoring. It is designed specifically for use in outdoor and indoor applications.

Reliable protection against fire – and against false alarms

The high immunity to false alarms of the flame detector protects against false alarms and their negative consequences. At the same time, the installed IR sensors are characterised by a fast response time—allowing the SharpEye 20/20MI IR3 to trigger an alarm quickly in case of fire.

Full performance, yet small and compact

Despite the lightweight, energy-conserving design, this compact version does everything you expect from a powerful IR3 flame detector: A detection distance of up to 40 metres (133 ft) and a wide field of view of 100° horizontally and 100° vertically.

Available in two output versions

The two models 20/20MI-1 and 20/20MI-3 offers two output options with a 4–20 mA current interface (stepped) and additional alarm and fault relays. Furthermore the type 20/20MI-3 is similar to the 20/20MI-1, but has lower sensitivity and is designed specifically for small areas that require fast and reliable detection. The integrated test circuit (BIT – Built-In-Test) supports both automatic and manual test runs.
