Raytek RAYMI320LTSCB15 MI3 Series Low Temperature Sensing Heads




MI3 Series – Smart and Innovative
Most IR temperature sensors on the market transfer measurements from the sensing head to the electronics as interference-prone analog signals in a very sensitive μV range, the MI3 models allow calibrated, digital temperature output directly from each sensor head.

MI3 – The World’s Smallest Stand-alone pyrometer
The Raytek® MI3 is a rugged, IP65 stainless steel miniature pyrometer with integrated electronics that can measure a wide range of temperatures. Just 14 mm (0.55 in) in diameter and 28 mm (1.1 in) long, the single piece OEM version is the smallest fully functional, stand-alone infrared temperature sensor for fixed installation on the market today. Designed for a wide range of applications, the sensor is housed in a rugged stainless steel enclosure to ensure long term performance, even in harsh industrial environments with ambient temperatures up to 180 °C (356 °F) without cooling. Cooling accessories not only add installation costs, they can leak and contaminate products, or condensation produced by cooling can obscure the sensor’s field of view and interfere with measurement accuracy.
