PIERRE

The PIERRE Pro Flood Sensor is designed for environments where water leakage detection is critical, such as basements, bathrooms, and utility rooms. It features a robust ABS construction with an IP67 rating, ensuring protection against dust and water ingress. The sensor is equipped with an NPN-type switching mechanism and outputs high and low signal levels depending on the presence of water, enabling seamless integration with alarm systems for immediate alerts.

Operating on a DC voltage range of 5-24V, the sensor has a maximum current of 0.15A and operates with minimal power consumption (0.5W). Its installation is straightforward, designed to be mounted on the floor or wall for optimal water contact. The device includes high insulation resistance, ensuring reliable performance even in humid conditions.

Warranty
