Connectivity’s analog infrared thermopile temperature sensor realizes non-contact high-precision temperature measurement solution

With the development of the medical and industrial markets, the demand for accurate non-contact temperature measurement is increasing. TE Connectivity (TE) is a global technology company in the field of connectivity and sensors. It produces non-contact analog infrared thermopiles that can meet various accuracy, packaging and performance requirements, adapt to the changing industry development needs, and help create safer and more reliable A sustainable, efficient and interconnected future.

The thermopile sensor measures the temperature by detecting the infrared energy emitted by the object. The measuring distance is wide, ranging from an inch to a few feet. The thermopile sensing element is composed of some small thermocouples on a silicon chip, which can absorb energy and generate an output signal.

“Providing reliable sensors and creating a safer, more sustainable and more interconnected future is our ultimate goal,” said Liu Xing, TE Connectivity product manager. “The simulated infrared thermopile measures temperature in a non-contact manner, with various lenses and filter membranes, and can be used in a variety of applications from industrial thermometers to climate control and medical equipment.”

TE’s analog infrared thermopile is widely used in the fields of automobiles, aerospace, industry, home appliances and medical equipment. The advantages are as follows:

The measurement temperature range is wide, as low as -40°C and as high as +300°C. The high-performance package uses a high-precision nickel resistor or NTC sensor as a reference, making TE thermopile easier to compensate and provide accurate output.

Multiple configurations of single or multiple pixels.

Optical filter options include standard flat windows and a series of silicone lenses for narrow field of view, which can filter specific wavelengths.

The sensor package is rugged and durable, including a fully sealed housing, a stainless steel package housing, and circuit board modules and connectors.
