Description
The Schneider Electric (Barber Colman) ETA500-24 is a Continuum-series copper averaging temperature sensor engineered for accurate ambient and duct temperature measurement in building automation and HVAC control applications. With a 24-foot copper sensing element, this averaging sensor captures temperature readings across a wide area rather than a single point, making it ideal for large duct runs, air handlers, and mixed-air applications where uniform temperature representation is critical.
Key Features
- 24-foot copper averaging sensing element for wide-area temperature measurement
- 1,000 Ohm (1K Ohm) resistance at 32°F (0°C) for precise signal output
- Designed for use with Schneider Electric Continuum building automation systems
- Copper sensing element provides reliable, consistent temperature response
- Suitable for duct, mixed-air, and large-space averaging applications
- Drop-in compatible replacement for Barber Colman ETA500-24 sensors
Application
The ETA500-24 is well-suited for commercial HVAC systems where accurate averaging temperature data is required to optimize equipment performance and energy efficiency. Its long copper element spans the cross-section of a duct or space, averaging out temperature stratification and delivering a reliable signal to the Continuum BAS controller.
