Raytek MI3 miniature infrared temperature transmitter system

The latest version of the Raytek MI3 miniature infrared temperature transmitter now has display and programming buttons accessible from the outside, and alternative versions for connection of between four and eight heads to one base unit.

For OEM applications, users can now connect the digital head directly to a PLC running suitable code - for which a development kit has been released. This reduces the cost of installation by more than 50%.

Temperature ranges have been extended to 1650°C (Model G5), response times reduced to 20 ms and close focus optics added for small targets. All versions have adjustments for emissivity, window transmissivity, background temperature, and signal processing such as average, peak and valley hold. Measurement accuracy is 1% in ambient temperatures (without cooling) to 120°C.

Options exist for process control using a PLC, where emissivity and ambient temperature can be set during a process, and process temperatures and head temperatures can be measured. Multiple input systems connect to the control system using RS485.

Full mounting hardware, windows, air purge, brackets and cooling housings allow the MI3 to be used in many harsh environments.
