Melexis contactless MEMS IR temp sensors avoid temp-induced errors

June 23, 2011 – PRNewswire — Melexis launched its 3rd generation of contactless micro electromechanical systems (MEMS) infrared (IR) temperature sensors in the MLX90614 family. This generation boasts high accuracy for automotive, medical, industrial and consumer applications.

The new MLX90614ESF-DCH and MLX90614ESF-DCI incorporate a refractive silicon lens to achieve small fields of view (down to 5°) so small objects can also be measured from further distances. They are able to measure human body temperature with a high medical accuracy over a wide operating range. In this particular application the accuracy is ±0.2°C. The parts are available in a standard setting TO-39 footprint with integrated lens.

Melexis minimizes temperature-variation-induced errors by 2 orders of magnitude using a built-in compensation technology on the MEMS devices. A secondary sensor measures the thermal disturbances and compensates the measurement result with internal digital electronics.

The sensors are factory calibrated for plug-and-play integration. They comply with medical and automotive electronics standards.

Samples and production volume are available.
