Lighting | Imaging | Telecom p Thermopile Infrared Detectors Quad Thermopile TPS 4339 Thermistor temperature reference included Internal aperture to avoid cross talk Standard gas filter sets for reference, CO, hydrocarbon, CO2 The quad thermopile sensor consists of four single thermopile chips mounted in a TO 5 . housing with a thermistor as temperature reference. The window size is 1.5 x 1.5 mm2 each. Due to the overall small sensor size the construction of a very compact equipment becomes possible. Applications in automotive exhaust gas control, multiple gas detection for the safety product market or air quality monitoring For further information please refer to the TPS 4339 product note Parameters TP S typical units 0.7 x 0.7 mm2 absorbi ng area 1.5 x 1.5 mm each channel DC sensitivity 75 V /W 500K BB w/o filter R esistance 75 kW Noise 21 nV /Ö Hz S ensitive area 4x Window size NEP D* 2 condition r.m.s. 300K 0.28 nW/Ö Hz 500K BB w/o filter 1.6 x 108 cmÖ Hz/W 500K BB w/o filter 1.0 TPS4339 Relative signal Right for modification reserved / WS /, 5.7.2001 4339 0.8 TC of sensitivity 0.02 %/K 0.6 TC of resistance 0.02 %/K 0.4 Time constant 25 ms 0.2 0.0 -80 -60 -40 -20 0 20 40 60 80 Operating temperature -40 100 °C non permanent S torage temperature -40 100 °C non permanent 100 kW 25°C 3964 K 25°C /100°C 60 ° at 50% poi nts Thermistor resistance Incidence angle in degree beta Field of view 4x 1.0 Relative signal output TPS 4339 0.8 -3 dB level 0.6 0.4 0.2 1 10 Frequency in Hz 100 Dimensions in mm Europe: PerkinElmer Optoelectronics GmbH Wenzel Jaksch Str 31 Wiesbaden / Germany Phone +49(0)611 492 0 Fax +49(0)611 492 170 USA: PerkinElmer Optoelectronics 2175 Mission Colledge Blvd Santa Clara, CA 95054 Phone +408 565 0830 Fax +408 565 0703 Asia: PerkinElmer Optoelectronics 47, Ayer Rajah Crescent #06-12 Singapore 139947 Phone +65 775 2022 Fax +65 775 1008 www.perkinelmer.com/opto D A T A S H E E T Four individual thermopiles with different infrared bandpass filters in TO 5 housing for NDIR gas sensing up to 4 gases possible
