In the field of temperature measurement, contact and non-contact temperature measurement technologies have distinct characteristics due to their differing principles. Contact methods, such as thermocouples and resistance temperature detectors, achieve high accuracy through direct heat exchange, but require thermal equilibrium, leading to measurement delays. Furthermore, their high-temperature resistance limits their application to extreme temperatures, and prolonged exposure to high temperatures can reduce accuracy and lifespan. Non-contact methods, on the other hand, are based on the principle of "no contact," preserving the temperature field and adapting to complex scenarios involving high temperatures and moving targets. They offer fast response times (2-3 seconds), but are susceptible to emissivity, distance, and environmental interference, requiring calibration to ensure accuracy, thus increasing measurement complexity. MFroniter has been deeply involved in the field of infrared temperature measurement for many years. Its flagship product, the MTP10-A6F8 MEMS infrared thermopile temperature sensor, has undergone extensive market testing and customer validation, earning widespread trust and recognition for its superior performance and establishing a strong reputation and market standing within the industry.
I. The working principle and advantages of MEMS infrared thermopile technology
The MTP10-A6F8 sensor utilizes MEMS infrared thermopile technology. Its core principle is to use a thermopile chip to detect the infrared energy emitted by an object, converting the thermal energy into an electrical signal via the Seebeck effect. The sensor incorporates an 8-14μm bandpass filter to precisely select the target infrared wavelength, effectively suppressing external interference. Furthermore, a high-precision NTC thermistor is integrated to compensate for environmental temperature variations, ensuring stable measurements across the entire temperature range. After internal signal processing, the thermopile output provides an electrical signal directly proportional to the temperature, suitable for various secondary development applications.
As a typical MEMS infrared thermopile temperature sensor with analog output, the MTP10-A6F8 offers the following advantages:
MEMS Thermopile Chip：Manufactured using MEMS technology, it features a miniaturized chip design and high integration, suitable for small-size devices.
TO-39 Package：The TO-39 metal package is compact and provides excellent electromagnetic shielding and environmental protection.
High Sensitivity: Accurately detects weak temperature signals, enabling fast response and high-precision measurement.
8-14µm Bandpass Filter: Equipped with a self-developed 8-14µm bandpass filter, it precisely filters the target infrared wavelength band, effectively suppressing environmental interference.
