INFRARED SENSOR
[attachment=27094]
Introduction
The sensing element used in the PASCO CI-6628
Infrared Sensor is a thermopile. Thermopile detectors
are voltage-generating devices that can be thought of
as a miniature array of thermocouples. The
thermopile is a high output, thin film, silicon based
device which has 48 thermopile junctions. The active
or ‘Hot’ junctions are blackened to efficiently absorb
radiation. The reference or ‘Cold’ junctions are
maintained at the ambient temperature of the detector
The blackening material used on the ‘Hot’ junctions
is capable of absorbing radiant energy from ultra
violet to the far infrared.
Using the Shutter Bracket
Note the orientation of components as illustrated in
Mount the shutter bracket to the Infrared
Sensor unit, with the included hardware, as shown. Do
not over tighten thumbscrew.
Limited Warranty
PASCO scientific warrants the product to be free from
defects in materials and workmanship for a period of
one year from the date of shipment to the customer.
PASCO will repair or replace, at its option, any part of
the product which is deemed to be defective in
material or workmanship. The warranty does not
cover damage to the product caused by abuse or
improper use. Determination of whether a product
failure is the result of a manufacturing defect or
improper use by the customer shall be made solely by
PASCO scientific.
