The P31 Water Level Sensor Plastic Float Switch is a reliable and cost-effective solution for detecting water levels in tanks, reservoirs, and industrial systems. Featuring a durable plastic float, the sensor operates by floating on the water's surface and activating a switch when the water level reaches a set point. Its simple design ensures long-lasting performance with minimal maintenance. The switch is easy to install and is commonly used for automatic water level control, overflow protection, and pump systems. Made from corrosion-resistant materials, the P31 float switch is suitable for both freshwater and saltwater applications, providing efficient and accurate level monitoring.
