Analogue Pyro IR Detectors

MPS pyroelectric detectors in standard TO packages are suitable for industrial and medical applications of infrared gas analysis (NDIR). Micro-Hybrid offers 2 and 4 channel detectors in standard TO39 packages. The variants have different filters with optimized absorption in the wavelength range of 4...6µm and are therefore ideal for the measurement of hydrocarbons (HC), carbon monoxide (CO) and carbon dioxide (CO2).  Our pyroelectric thin film sensor is the basis of outstanding performance features such as high detectivity and modulation frequencies.

Applications of Pyro-Sensors

Gas measurement, spectrometry and flame detection are among the typical applications for infrared measurements with pyro detectors. The MPS Pyro detectors from Micro-Hybrid are specially designed for infrared analysis of gases in the optical wavelength range from 4 to 6µm. In this spectrum hydrocarbons, carbon monoxide and carbon dioxide are analyzed. These gases are relevant as process gases and emissions of industry processes as well as respiratory gases in medical applications.
