Trane SWT3335 Thermal Sensor Flow Switch 24V

The Trane SWT3335 24V thermal sensor flow switch is a vital part of monitoring fluid flow in Trane chiller HVAC systems. The little device 3.42" x 3" x 2", has a thermal sensor built into it that detects movement in water. When water passes through the switch, the sensor detects a temperature change and delivers a signal to the HVAC system. This signal guards against problems such as overheating and low flow conditions to protect the equipment from damage. Constructed robustly and its IP67 housing keeping it out of water and dust, the high-pressure settings used in HVAC systems. It has a pressure rating of 25 Bar. It operates on a low voltage of 24 volts AC/DC.
