The dual thermopile sensor TPS 2534 employs two single thermopile chips
mounted in a TO 5-type housing with a 30 kV 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.
