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 ther-
mopile 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 sen-
sitive 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 TO-
housing serves as the ambient
temperature reference.
Features and Benefits
• Miniature TO-46 housing (4.7 mm Ø)
• Small and perfectly round measurement
spot
• Large output voltage
• Large field of view of 115°
• High signal to noise ratio
• 5.5 µm IR longpass filter
• Stable signal in the case of ambient thermal
shock due to the small TO-46 housing
• RoHS compliant – Si-chip made by
standard CMOS processes
Applications
• High precision temperature sensing
• Ear thermometer
• Infrared pyrometry
