Electronica 2016: Sensor technologies for temperature measurement

Two sensing technologies for temperature measurement across industrial sectors have been unveiled by global microelectronics company Melexis, at this year’s Electronica trade show.

The products presented today at the Melexis stand in Munich include a low-cost infrared sensor built for safety and convenience applications, as well as a high-performance platform designed to provide rapid response and high accuracy when measuring extreme temperatures.

“These two new devices provide further evidence of how inspired engineering can deliver real-world benefits to future applications that support safety, comfort and efficiency,” said Damien Macq, Sensor Business Unit Manager at Melexis.

At the low-cost end of the scale, Melexis unveiled the MLX90640 infrared sensor array, a 32 x 24 pixel device suitable for use in applications including fire prevention systems, smart buildings and surveillance cameras. The device has a -40°C to 85°C operational temperature range and can measure object temperatures between -40°C and 300°C.

For more high-performance applications, Melexis presented the MLX90342 – a quadruple thermocouple interface that provides rapid response and high accuracy when measuring extreme temperatures. The product is specifically designed with the automotive sector in mind, for use in engine and exhaust thermal management and control. The MLX90342 supports a -40°C to 1300°C thermocouple temperature range and has an operating temperature specification spanning -40°C to 155°C.

The new products, Mcaq says, illustrate Malexis’ solutions to temperature sensing requirements across industries: “from the demanding performance and reliability needs of harsh, high-temperature automotive environments to the challenges associated with applications that require high-performance, high-quality sensing at competitive price points.”
