Product Overview
Automation Components, Inc. (ACI) built the A/CP-D-8"-4X to read air temperature from inside a duct. The 8 inch probe passes through the duct wall from a mounting flange, and the thermistor follows the 10K Type II curve, referenced at 10K ohms at 77°F. The 4X enclosure keeps the terminations sealed where moisture or washdown is a concern.

Frequently Asked Questions
Which controllers can read it?
Any controller input configured for a 10K Type II thermistor.
Is this the 4X enclosure version?
Yes. The cover label reads Duct 8", 4X, and the cover seals on a gasket.
What does the -8"-4X part of the number mean?
The 8 is the probe length in inches and 4X is the enclosure rating. The sensing curve is the 10K Type II named on the label. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
A thermistor this size spends its working life reporting one number from inside a duct nobody looks into. Set it in the airstream and let it talk.
