eMagTech 2pin Water Pressure Flow Sensor Switch Compatible with Cleverspa Series Massage Bathtubs Portable Hot Tubs

Compatibility: This product is compatible with CleverSpa series massage bathtubs/portable hot tubs. Its core function is as a safety switch, allowing the heater to operate only when it detects sufficient water circulation, preventing dry boiling and protecting both the heater and the user. How it works: This sensor is installed inside the water heater pump or in the water flow path. When the pump starts, the water flow generates pressure, pushing the diaphragm or piston inside the sensor, closing the switch contacts and sending an electrical signal indicating "normal water flow" to the control board. Material: This product is specially designed with metal and plastic for a long lifespan and resistance to damage. Easy Installation: Direct replacement without adjustment, ensuring perfect compatibility and high reliability., Manufacturer: eMagTech
