Do you have a question about the MI3 and is the answer not in the manual?

Questions and answers

Jeff Crabb
April 7, 2025

I am currently installing 4 modules, each with 2 of the Raytek MI3 units. 7 of the units arrived with the normal display (Bottom Unit in photo), but 1 has only a full white block in the display. Is this indicative of a failed unit, or would this require external adjustments. These units always work when received, so I am unfamiliar with the required troubleshooting.

    Basics 4 Basics 4.1 Measurement of Infrared Temperature All surfaces emit infrared radiation. The intensity of this infrared radiation changes according to the temperature of the object. Depending on the material and surface properties, the emitted radiation lies in a wavelength spectrum of approximately 1 to 20 µm. The intensity of the infrared radiation (heat radiation) is dependent on the material.

Please note that:  The metal housings of the sensing head and the MI3 communication box are electrically connected to the shield of the head cable.  All inputs and outputs (except the alarm output and the outputs of the Comm Box (DIN 6TE, analog)) use the same ground and are electrically connected to the power supply.

  • Page 26: Installation

    Installation 5 Installation 5.1 Positioning Sensor location depends on the application. Before deciding on a location, you need to be aware of the ambient temperature of the location, the atmospheric quality of the location, and the possible electromagnetic interference in that location. If you plan to use air purging, you need to have an air connection available.

  • Page 45 Inputs The sensor is capable of improving the accuracy of target temperature measurements by taking into account the ambient or background temperature. This feature is useful when the target emissivity is below 1.0 and the background temperature is significantly hotter than the target temperature. For instance, the higher temperature of a furnace wall could lead to hotter temperatures being measured especially for low emissivity targets.

Note that this setting influences the digital interfaces like RS485 for both object and head ambient temperature. <Key Enter Lock> the box has a user interface lockout feature that keeps the box from being accidentally changed from the control panel (locked by default under DataTemp Multidrop Software and Profinet communications).

  • Page 54: Peak Hold

    Operation Attention: The disadvantage of averaging is the time delay of the output signal. If the temperature jumps at the input (hot object), the output signal reaches only 90% magnitude of the actual object temperature after the defined average time. 8.5.2 Peak Hold The output signal follows the object temperature until a maximum is reached.

  • Page 55: Advanced Peak Hold

    Operation Temp output temperature object temperature hold time hold time Time Figure 37: Valley Hold A defined hold time of 999 s (symbol “∞” in the display) will put the device into continuous valley detection mode. A low level input (GND) at external input FTC3 will promptly interrupt the hold time and will start the minimum detection again.

  • Page 56: Advanced Valley Hold

    Operation 8.5.5 Advanced Valley Hold This function works similar to the advanced peak hold function, except that it will search the signal for a local minimum. 8.5.6 Advanced Peak Hold with Averaging The output signal delivered by the advanced peak hold functions tends to jump up and down. This is due to the fact, that only maximum points of the otherwise homogenous trace will be shown.

  • Page 58: Avoidance Of Condensation

    Options 9.1.1 Avoidance of Condensation If environmental conditions makes water cooling necessary, it is strictly recommended to check whether condensation will be a real problem or not. Water cooling also causes a cooling of the air in the inner part of the sensor, thereby decreasing the capability of the air to hold water. The relative humidity increases and can reach 100% very quickly.
