The BAPI BA/10K-2-D-4-NB-10 is a precision duct-mount temperature sensor engineered for building automation systems and commercial HVAC applications. Featuring a 10K Type II thermistor element, this sensor delivers accurate, responsive air temperature readings directly from the supply, return, or mixed-air duct stream — making it an essential component for economizer control, VAV systems, air handling units, and energy management strategies.
Product Overview
Built by Building Automation Products, Inc. (BAPI), the BA/10K-2-D series is a trusted workhorse in the commercial controls industry. The no-base (NB) configuration allows for a clean, low-profile installation directly through the duct wall without a surface-mount enclosure, ideal for tight mechanical spaces or applications where a separate junction box is used.
Key Features
- 10K Type II thermistor sensing element for broad BAS controller compatibility
- 4-inch stainless steel insertion probe for accurate mid-duct air temperature measurement
- 10-foot pre-wired cable for flexible field installation without splicing
- No-base (NB) design for direct duct penetration and low-profile mounting
- Compatible with most major building automation and direct digital control (DDC) systems
- Suitable for supply air, return air, mixed air, and exhaust air duct applications
