Part # Distributor Manufacturer Product Category Description
PIN-DSIN-TEC   OSI Optoelectronics Photodiodes Dual Sandwich Detectors or Two Color Detectors are mostly employed for remote temperature measurements. The temperature is measured by taking the ratio of radiation intensities of two adjacent wavelengths and comparing them with the standard black body radiation curves. THe advantages of optical...
