Schneider Electric (Barber Colman) ETR500 Room Temperature Sensor, 10K Ohm, Type 3

The Schneider Electric (Barber Colman) ETR500 is a precision room temperature sensor engineered for commercial HVAC and building automation applications. Featuring a 10K Ohm Type 3 thermistor element, this sensor delivers accurate, reliable temperature readings to controllers, DDC systems, and building management systems throughout occupied spaces.

Key Features

• 10K Ohm Type 3 thermistor sensing element for high-accuracy room temperature measurement
• Designed for wall-mount installation in occupied spaces — ideal for offices, classrooms, corridors, and commercial environments
• Compatible with Schneider Electric (Barber Colman) controllers and a wide range of third-party DDC/BAS systems accepting Type 3 thermistor inputs
• Low-profile, clean aesthetic housing blends with standard commercial wall finishes
• Simple two-wire connection for straightforward field wiring and commissioning
• Durable construction built to withstand the demands of continuous commercial use

Application

The ETR500 is suited for zone-level temperature sensing in variable air volume (VAV) systems, fan coil unit controls, and centralized building automation networks. Its Type 3 thermistor output integrates directly with Schneider Electric’s Andover Continuum, TAC Vista, and EcoStruxure Building platforms, as well as compatible third-party controllers.
