MI3 Series infrared temperature-measurement system
This company’s MI3 Series infrared temperature-measurement system now includes several new high-temperature sensing heads (M13 1M and M13 2M). These are constructed of IP65 (NEMA 4) stainless steel and have a separate communication module. They provide a 1-μm spectral response (offering a measurement range of 500–1,800°C), and 1.6- μm spectral response (250–1,400°C). The sensing heads are available with standard laser sighting, and provide fast (10- μs) response time. The M13MCOMM multi---channel communication box supports up to four sensing heads in a DIN-mountable package. All operating parameters can be accessed and configured through the standard user interface, or with the company’s DataTemp software via a USB 2.0 digital interface. A range of network communication interface options, including RS-485, Modbus, and Profibus, enables seamless integration into existing control equipment or OEM systems. A user-programmable alarm output enables alarm, control redundancy, and simple on/off capabilities.

Marathon MM 3M infrared sensor
The Marathon MM 3M infrared sensor uses shorter IR wavelengths to minimize errors due to the uncertainty of emissivity. This makes it less sensitive to changes in emissivity on the target material than long-wavelength sensors and enables it to provide more accurate readings across multiple targets at varying temperatures. The sensor features precision variable-focus optics that allow it to be accurately focused with a touch of a button, and a NEMA-4 sealed user interface that guarantees the integrity of the electronics. The 3M is the latest addition to the Marathon MM Series, which includes six models that cover the ranges of –40°C to 800°C (low), 250°C to 1,100°C (medium), and 300°C to 3,000°C (high). All of the units provide enhanced continuous remote temperature monitoring, ease of installation and sighting, video surveillance and documentation, remote PC interface, flexible configuration, and field calibration software.
