MI3 1M/ 2M

Description

The Raytek® MI3 is a powerful two-piece infrared temperature measurement system with miniature sensing head andseparate communications electronics. The sensor is small enough to be installed just about anywhere, yet it outperforms much larger systems. Available in either a rugged cast metal electronics enclosure, an innovative multi-channel DIN mountable enclosure, or low cost OEM configurations, the MI3 offers a host of advanced signal processing features you won’t normally find in sensors costing much more. The MI3 features a variety of sensing head options. High temperature sensors with a measurement range of 250°C to 1800°C (482°F to 3272°F), fast response (10 mSec), 1.0, 1.6 µm spectral response sensors and laser sighted 100:1 optics provide an impressive solution for your process needs. The rugged stainless steel sensing head ensures reliable long term performance in the harshest industrial environments. Although the MI3 sensor is small in size, it has all the performance you need for the most demanding applications.
