TPS2534

DATASHEET Optoelectronics TPS 2534 - Dual Channel Thermopile Two Thermopiles with Individual Infrared Filters Description The dual thermopile sensor TPS 2534 employs two single thermopile chips mounted in a TO-5 housing with a 40 kΩ thermistor as temperature reference. The cap has two windows of size 2.3 x 2.6 mm2 each which can be equipped with different infrared bandpass filters. The sensor is perfectly suited to gas detection by IR absorption. For further information please refer to the TPS 2534 product note.
