DATASHEET SENSOR SOLUTIONS Thermopile Sensor TPS 232 / 3214 Revision - Date: 2007/11/12 Introduction PerkinElmer introduces the new TPS 232 as part of the TPS 23x family for low-cost remote temperature measurement applications. It consists of a silicon (Si) based thermopile chip in a metal housing with IR transmissive filter. The Si-chip carries a series of thermoelements, forming a sensitive area covered by an IR absorbing material. With its optimized output signal, the TPS 23x family replaces the TPS 43x series by offering better performance at a lower cost. The thermopile sensing principle allows for broadband IR measurements. PerkinElmer Optoelectronics thermopile sensors are equipped with a MEMS / MOEMS state-of-the art sensing element and an optical filter that defines the sensitive spectral range of the sensor and at the same time serves as device window. Properties of TPS 232 The TPS 232 is a small thermopile sensor TO-46 (4.7 mm cap diameter) housing. It is especially suited for ear thermometer solutions. The sensor employs a very small thermopile chip with a 0.5 mm round active area allowing small spot sizes in pyrometer applications. The chip is optimized for a large output signal. The round window is equipped with a PerkinElmer’s standard IR longpass filter with 5.5 µm cut-on wavelength. The frequency behavior corresponds to a low pass characteristic. A 100 kΩ thermistor inside the TOhousing serves as the ambient temperature reference. Features and Benefits ...
