Raytek released the MI3 Series of infrared temperature measurement sensors. The MI3 Series represents a new generation of performance and innovation in noncontact temperature monitoring for original equipment manufacturer (OEM) applications and manufacturing processes.
Combining a rugged IP65 (NEMA 4) stainless steel sensing head with a separate communication module, the MI3 should meet any noncontact temperature measurement requirement.
Infrared thermometers, such as the MI3, are the fastest, safest and most cost-effective way to measure critical temperatures necessary for process control and automation. “Energy costs are typically one of the top three operating expenses in any manufacturing facility, and process heating is the largest portion of this expense,” said Bill Kolbeck, Raytek Product Manager – Point Sensor Products. “The Raytek MI3 reduces 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.”
Kolbeck indicated the new MI3 sensor provides a broad choice of sensing head temperature ranges and spectral responses, a standard USB 2.0 digital interface for easy set-up and configuration, a fully programmable electronics platform, and response times as fast as 20 mSec. The thermometer’s multiple sensing head interface supports up to eight individually addressable heads per communication box.
The Raytek MI3 Series sensors offer a choice of scalable 0/4 to 20 mA and 0 to 5/10 VDC analog outputs, or Type J, K, R or S thermocouple outputs, as well as an optional RS485 network interface – thus, enabling seamless integration into existing control equipment or OEM systems.
Standard USB 2.0 communication facilitates sensor configuration and is valuable for troubleshooting when the device operates in hostile or remote 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.
Precise, high-resolution silicon optics allow the MI3 sensor to provide a range of optical resolutions (2:1, 10:1 or 22:1). For high-volume OEM applications, the sensing heads allow a direct digital interface to the host machine controller.
The MI3MCOMM multichannel communications box supports up to four high-performance, miniature sensing heads in a 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 Raytek DataTemp multidrop software via the USB 2.0 digital interface.
The MI3’s user-programmable, isolated alarm output is an easy way to achieve alarm and control redundancy or provide simple on/off control capabilities. Its optically isolated relay allows for local alarm capability, eliminating the need for separate limit switches or alarms.
Other standard MI3 features include: adjustable emissivity, transmissivity, peak hold, valley hold and signal averaging; and configurable inputs for emissivity control, ambient background compensation and trigger/hold input.
