PerkinElmer Optoelectronics TPS232
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 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 kthermistor 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

1.2 Handling Requirements
Stresses above the absolute maximum ratings may cause damages to the device. Do not
expose the sensor to aggressive detergents such as Freon, Trichloroethylene, etc.
Windows may be cleaned with alcohol and cotton swab. Hand soldering and wave
soldering may be applied by a maximum temperature of 260°C for a dwell time less than
10 s. Avoid heat exposure to the top and the window of the detector. Reflow soldering is
not recommended.
