Automation Components Inc (ACI) A/CP-D-12-GD Thermistor

The Automation Components Inc (ACI) A/CP-D-12-GD Thermistor is a high-precision duct temperature sensor engineered for HVAC Building Automation Systems (BAS) and light industrial environments. This 10K Ohm Type II thermistor features a negative temperature coefficient (NTC), ensuring reliable resistance temperature detector performance for air handling unit (AHU) monitoring and zone control applications. To ensure long-term durability, the sensing element is double encapsulated, a design choice specifically implemented to prevent sensor failures caused by moisture infiltration or harsh condensate environments. The 12-inch stainless steel probe is ideal for mid-sized ducts, allowing for accurate center-stream measurement. For streamlined installation, the unit includes a built-in mounting flange and a specialized foam unit pad that dampens mechanical vibrations and provides an airtight seal against the ductwork. Whether you are managing return air temperatures or mixed air systems, this 12-inch duct sensor delivers the stability and accuracy required for modern energy management.

Key Benefits:

• Moisture Protection: The double encapsulated sensor prevents moisture-related drift and failures in high-humidity airflow.
• Easy Installation: Features a galvanized metal mounting flange for rapid, secure attachment to metal ductwork.
• Vibration Dampening: Integrated foam pad seals the mounting point and reduces mechanical noise from HVAC equipment.
• Broad Compatibility: The 10K Type II curve is a standard for many industry-leading building automation controllers.
• Precision Performance: Designed for critical temperature monitoring in discharge, supply, and return air applications.

Common Questions:

How do I choose the correct probe length?
For the most accurate duct temperature sensor readings, the probe tip should ideally reach the center of the duct. This 12-inch model is best suited for ducts between 18 and 24 inches in width or diameter.

Can this sensor be used in outdoor air intakes?
While the A/CP-D-12-GD is double encapsulated to resist moisture, the galvanized steel (-GD) enclosure is rated NEMA 1. For direct outdoor exposure, a NEMA 3R or 4X rated enclosure is typically recommended.

Is the thermistor polarity sensitive?
No, this 2-wire thermistor is not polarity sensitive, making wiring into your HVAC controller straightforward and error-free.
