DS1603

The DS1603 V1.0 ultrasonic liquid level sensor from Dallas Semiconductor provides real-time, non-contact liquid level monitoring within closed containers. This sensor can be attached to the bottom center or side wall of a container to detect liquid height or presence. It features a 1 millimeter resolution and a measurement range of 5cm to 200cm.

The sensor operates within a temperature range of -15°C to +60°C and is built with a rugged Plastic ABS housing with internal circuit potting, meeting IP67 waterproof standards. It utilizes a 2.0MHz frequency ultrasonic sensor with high solid penetration, making it suitable for containers made of metal, plastic, and other materials. The DS1603 V1.0 series offers various connection type options, including UART, RS485, Switch output, and 0-5Vdc analog voltage output, providing flexible interface capabilities.

This sensor is recommended for real-time liquid height monitoring in closed containers made from stainless steel, iron, glass, ceramic, or non-foamed plastics. It is also suitable for monitoring liquids with non-serious deposition or miscibility of mixed liquids, and for use in smart liquid level monitoring control systems such as smart water bottles, beer barrels, and LPG containers.
