Infrared (IR) sensors of the Raytek MI3 Series
The World’s Smallest Infrared Pyrometer
Raytek GmbH, Berlin, Germany, has launched a new generation of pyrometers. The infrared (IR) sensors of the Raytek MI3 Series consist of a miniature measuring head and separate communication electronics with the sensor head also functioning as an independent pyrometer. With a length of 28 mm and a diameter of 14 mm, the sensor is – according to the manufacturer – the world’s smallest fully functional infrared pyrometer.
The series is characterized by an innovative multi-head design and digital communication between sensor head and communication box. In addition, the pyrometers have functions such as automatic self-monitoring, an optically insulated alarm output in every communication box and an extended power supply range of 8 to 32 VDC. The multi-head design allows up to eight individually addressable measuring heads to be connected to one communication box. Plug&Play operation via the automatic head detection (patent pending) is possible thanks to the digital communication. It also facilitates the direct integration of the sensor heads into control systems at machine level and reliable data transmission when used on moving parts, e.g. on robot arms or trailing cables.
The miniature sensors embedded in the stainless steel housing can be operated at ambient temperatures of up to 120°C without cooling. They have a sturdy electromagnetic compatibility (EMC) and withstand higher field strengths than required by the applicable standards. They produce stable measured values even with widely fluctuating ambient temperatures. A temperature measuring range from -40°C to 1,650°C, several spectral models and a user-programmable sensor platform allow even sophisticated applications to be served, such as in the plastics processing and packaging industry.
