Raytek has expanded the capabilities of its compact, digital MI Series infrared (IR) temperature sensor
The MI sensor now features increased optical resolution, optimising its performance in demanding process control environments and allowing direct replacement of contact probes.
Due to its miniature size and broad feature set, the MI Series is one of the top selling IR sensors in the world.
The new family of MI sensors is suited for a wide range of applications in thermoforming and drying processes, paper mills, printing, paint booths, food and tobacco processing, and many more.
The thermometers can achieve up to 22:1 optical resolution and withstand ambient temperatures as high as 180C without any cooling.
This allows accurate measurement of very small spot sizes in confined spaces and difficult ambient conditions.
According to Frank Schneider, Raytek IR Thermometry Product Manager, the enhanced MI Series sensors have twice the optical resolution of earlier models setting a new standard for the non contact IR temperature sensor market.
He said, "Raytek has long been an innovator of temperature sensor technology, and our continued development of the MI family has resulted in a compact thermometer that outperforms much larger, more expensive systems".
"Process end users can now benefit from a miniature sensor with maximum performance".
The Raytek MI Series is a two piece infrared temperature measurement system with a miniature sensing head and separate electronics, covering a temperature range from -40 to 600C.
The sensor is small enough (14mm diameter, 28mm length) to be installed just about anywhere.
It is housed in a rugged, stainless steel enclosure with IP65 rating, ensuring long term performance even in harsh industrial processes.
The MI electronics offer many signal processing features, including emissivity, sample and hold, peak hold, valley hold, and averaging function, all of which are adjustable on a five digit LCD user interface.
Raytek MI Series sensors can be seamlessly integrated into existing control equipment or OEM systems.
They include an optional RS485 interface, which allows up to 32 sensors to be networked in a multi drop configuration, reducing installation costs and facilitating the design of custom equipment.
Raytek DataTemp software enables easy remote sensor control and data collection via a standard RS232 communication interface.
