Description
In recent years, thermopile detector
technology has opened up a large
variety of industrial and commercial
applications for non-contact, infrared
temperature measurements. Aside
from well-known thermopile
applications in ear thermometers
and hand held pyrometers, new
applications include temperature
control in microwave ovens or other
household appliances such as
toasters and hair dryers, home and
automotive climate control, and a
growing number of other industrial
functions.
Most of these applications require an
accurate signal output independent
from ambient temperature variations.
Up to now, this was achieved by
external analog signal-processing
circuits or, for high accurate devices,
by an external microcontroller.
However, with growing high-volume
applications, there is a strong demand
for miniaturization and simplification of
the circuitry.
PerkinElmer Optoelectronics now
satisfies this demand by providing the
very first fully integrated and pre-
calibrated thermopile module, TPMI, in
a TO-5 size housing. Depending on
the temperature range, an accuracy
up to ±1 °C is achievable. Its modular
design, where optics, spectral filter
ranges, PCB geometry, and
connectors can be chosen individually,
makes it the ideal infrared solution for
the flexible implementation of remote
temperature measurement into any
application.
Applications
• Miniature, remote non-contact
temperature measurement
(pyrometer)
• Temperature-dependent switch for
alarm or thermostatic applications
• Residential, commercial, automotive,
and industrial climate control
• Household appliances featuring a
remote temperature control, i.e.,
microwave ovens, toasters, or hair
dryers
• Temperature control for laser printers
and copiers
