Thermal IR detectors
The thermo-electric IR detectors of the MTS series (Micro-Hybrid Thermopile Sensors) are characterized by a particularly high detectivity and longevity.
They are suitable for non-contact temperature measurement as well as for NDIR gas analysis. IR thermopiles, also known as thermopiles, detect broadband IR radiation. The basis of each detector is formed by the so-called thermocouple. Thermal diffusion currents of two different metals (Seebeck effect) generate an electrical voltage which is transmitted and processed as a measurement signal. The sensitivity of the detector significantly influences the quality of the measurement result.
Worldwide best detectivity up to 7.2 x 108 cmHz1/2/W
up to 295 V/W

- Also suitable for chemical processes
Structure and variants of MTS thermopile detectors
MTS highly sensitive thermopile detectors are available in TO46 and TO39 as single, dual or four channel detectors. We offer single channel detectors with 80 thermocouples for IR temperature measurement and with 200 thermocouples for gas analysis. By adapting our IR sensors with different optical filters we offer individual product solutions for thermometry, non-contact measurement or gas monitoring (two narrowband windows, two-channel output).
Applications Thermal IR Detectors
Thermal IR detectors are used in many applications in industry, research and science, including gas measurement, spectrometry, temperature measurement and monitoring, and pyrometry. Since temperatures and gas concentrations are among the most important process parameters, their reliable detection is an elementary component for monitoring and ensuring determined processes.
