Trane SWT3334 Thermal Flow Sensor Switch 24V

Trane SWT3334 is a 24V Thermal Sensor Flow Switch used in the measurement of fluid flow in HVAC systems. This switch is based on thermal principle, a heated sensor measures the change in temperature due to flow of fluids. When flow is present the sensor cools and this switches the circuit. On the other hand, no flow enables the sensor to heat up and therefore change the state of the switch. In use with chillers, boilers together with other hydronic HVAC equipment, it promotes proper flow of the fluids for heat transfer. They include, Detecting flow accurately, it helps to guard equipment from being damaged by low or no flow situations, enhancing the systems utilization and durability.
