Schneider Electric (Barber Colman) ETI800-4 4" Temperature Immersion Sensor

The Schneider Electric (Barber Colman) ETI800-4 Temperature Immersion Sensor is a component designed to measure liquids within a system. Featuring a 4-inch immersion probe, it is inserted into a compatible well or mounting location where direct contact with the fluid is required. The sensor detects temperature changes and transmits corresponding signals to the control system for monitoring and regulation. In HVAC systems, it is used in applications that require fluid measurement, providing continuous input to support temperature-based control operators and overall system operation.
