This technical note describes the first programmable and
pre-calibrated, fully integrated thermopile module (TPMI)
with ambient temperature compensation in TO-5 housing.
The new product is designed with a powerful integrated
circuit (ASIC), combining the thermopile sensor with
signal processing and interface for calibration and
configuration on a small space.
Digital calibration via a serial interface enables a plug &
play function. Memory cells and register access offer a
maximum of flexibility to change factory calibration or
settings for adaptation of the sensor to the specific
application.
With its superior performance over today’s thermopile
modules with discrete external circuit, the PerkinElmer
TPMI has the potential to advance fast into existing and
new applications.
For development purposes, an application kit is available,
which enables the access of all features via a PC based
program.
