Fully Calibrated High Accuracy MEMs Infrared Temperature Sensor
TESSENDERLO, Belgium, June 21, 2011 /PRNewswire/ –
Melexis today launches its 3rd generation of contactless MEMs infrared
temperature sensors. The high accuracy of the newest member of the MLX90614
family makes it suitable for limitless applications in automotive, medical,
industrial and consumer markets.
12 years ago Melexis pioneered MEMs contactless infrared temperature
sensors. This family of successful MEMs sensors is now built into dashboards
of cars to guide the HVAC system. It is used in ear- and forehead
thermometers, microwave ovens, green air conditioning systems, process
control and maintenance systems, medical blood analyzers and mobile phones.
A common problem in the use of infrared thermometers is the error
induced due to fast temperature variations and/or thermal gradients. Melexis
is able to reduce this effect by 2 orders of magnitude using our built-in
compensation technology. This technology is based on the use of a secondary
sensor to measure the thermal disturbances and compensate the measurement
result with internal digital electronics. In this way our thermometers can
be used in environments where most other infrared sensors fail.
Luc Buydens, Product Line Manager Non-Contact Thermometers at Melexis
comments: “Our customers tell us that a high accuracy is an absolute
requirement. Therefore Melexis delivers the sensors factory calibrated,
making them plug and play thermometers: they read out a complete temperature
signal, ready to use in their application. Furthermore our products comply
with the high automotive and medical standards”
The new MLX90614ESF-DCH and MLX90614ESF-DCI incorporate a refractive
silicon lens to achieve small fields of view (down to 5 degrees) so small
objects can also be measured from further distances. Furthermore 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
0.2degrees C. This makes them ideal for forehead thermometers and public
area fever scanning gates.
The parts are available in a standard setting TO-39 footprint with
integrated lens. Samples and production volume are available.
