Thermopile Infrared Detectors
Dual Channel Thermopile TPS 2534
Two thermopiles with individual infrared filters
Thermistor temperature reference included
Applications: infrared absorption (NDIR) gas sensing
with reference channel
The dual thermopile sensor
TPS 2534
employs two single thermopile chips
mounted in a TO聽5-type housing with a 30聽kV thermistor as temperature
reference. The cap has two windows of size 2.3 x 2.6聽mm
2
each which can be
equipped with different infrared bandpass filters. The sensor is perfectly suited
to gas detection by IR absorption.
