TPS2534

The TPS2534 is a kind of dual thermopile sensor. The TPS2534 device adopts 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.

The following is about the specifications of TPS2534: (1)DC sensitivity: 42 V/W typ at 500K BB w/o filter; (2)resistance: 30 k typ; (3)noise: 30 nV/Hz typ at r.m.s 300K; (4)NEP: 10.7 nW/Hz typ at 500K BB w/o filter ; (5)TC of sensitivity: -0.01%/K; (6)TC of resistance: 0.02%/K; (7)operating temperature: -40 to 100 when non permanent; (8)storage temperature: -40 to 100 when non permanent.
