Melexis “Distance-to-Spot” studio simplifies sensor selection
Selecting the correct non-contact far-infrared (FIR) temperature sensor can be challenging due to performance and application factors, including the target object’s size and distance. Experimental trial and error can be complicated and time-consuming, potentially wasting development resources. To address this, Melexis has launched an online tool to support its MLX90614 product range.
For any given application, engineers looking to deploy FIR sensors need to consider a wide range of parameters, including the sensor’s field of view (FOV). The primary difficulty with using FOV alone is that it’s a simplification that can lead to errors in the sensor selection, often failing to deliver the required precision.
Melexis has developed an online studio to streamline the selection of its extensive portfolio of MLX90614 FIR sensors, ensuring engineers can quickly find the right device for their application.
Engineers using the tool simply need to enter the following application information:
● The diameter of the measured object
● The distance to the measured object
● The expected temperature range of the measured object
● The maximum expected temperature difference between the object and its background
● The maximum acceptable temperature deviation due to the distance to spot ratio
From here, the selection can be further narrowed by setting the ideal supply voltage and whether medical accuracy is required. The tool then suggests sensor(s), considering each device’s parameters.
“FIR sensing is a crucial part of many modern applications, from cooking to safety monitoring in industry, but choosing the right sensor without manufacturer assistance can be incredibly difficult,” said Joris Roels, Marketing Manager at Melexis. He continued, “We designed this tool to be a simple, user-friendly online resource that lets engineers easily identify the correct sensors for their application, helping them to avoid development mistakes.”
