RAYTEK® MI3 World’s Smallest Stand-alone Pyrometer Gains Integrated Network Communication

01 August 2011

RAYTEK® has enhanced its MI3 Series infrared temperature measurement sensors with new integrated network communication options. The RAYTEK MI3 sensors are now compatible with the Modbus® and PROFIBUS® network protocols, allowing them to be used in a wide range of applications requiring digital communication for field devices.

The Raytek MI3 Series represents a new generation of performance and innovation in noncontact temperature monitoring for Original Equipment Manufacturer (OEM) applications and manufacturing processes.

These high-performance IR sensors reduce energy costs by allowing tighter process control and more efficient process heating. Improved control performance usually results in less product variation, higher product quality and increased throughput.

Designed to deliver industry-leading performance and flexibility at the lowest installed cost per measurement point, the Raytek MI3 Series sensors combine a rugged IP65 stainless steel sensing head with a separate communication box.

They include a broad choice of sensing head temperature ranges and spectral responses, a standard USB 2.0 digital interface for easy sensor set-up and configuration, a fully programmable electronics platform, and response times as fast as 20 ms. The sensors’ innovative multiple sensing head interface supports up to eight individually addressable heads per communication box (metal).

Optional network communication with either Modbus or PROFIBUS facilitates sensor configuration and is valuable for troubleshooting when the device is installed in hostile locations. Additionally, this capability saves maintenance time and minimizes technician exposure to hazardous environments. Robust field calibration software also allows on-site calibration of sensors, which further reduces service time and expense

The MI3 multichannel communications box supports up to four high-performance, miniature sensing heads in a convenient DIN-mountable package. All sensor-operating parameters are easily accessed and configured through the standard user interface with large backlit LCD display, or with the powerful Raytek DataTemp® Multidrop software via the USB 2.0 digital interface.
