The small size and low cost of the OS39 Series infrared thermocouples makes them a natural choice for a variety of non-contact temperature measuring applications. They have a wide measuring range of -20 to 300°C (-4 to 570°F) with a full scale accuracy of 1.5% and 0.25% full scale repeatability. Available output types are non-linear 5 volt, 10 mV/degree, J and K thermocouple. The low output impedence of less than 10 ohms makes these units compatible with standard temperature meters and controllers, avoiding offsets in temperature readings due to large impedence outputs which is inherent in other infrared thermocouples. These revolutionary low cost units make them ideal choices for multiple target measurement such as in paper and plastic production, printing process applications and textile finishing. The optional air purge/cooling jacket allows the sensor to be at an ambient temperature of 150°C (300°F) while at the same time keeping the optics clean from dirt, dust, and protected from vibrations and rapid ambient temperature changes. The jacket uses an air flow of only 90cfm (2.5cmh) of clean air for operation.
