Reliable ultrasonic sensor optimized for use with wireless node

The K50U Ultrasonic Sensor Features Plug-and-Play Compatibility for Wireless Tank Level Monitoring.

Optimized for use with Banner’s Q45U Wireless Node, the pair provides a cost-effective, plug-and-play solution to monitor levels in mobile or remotely located tanks and totes.

The K50U reliably detects the distance from the target to the sensor in ranges between 300 millimeters (11.8 in) up to 3 meters (118 in). It also features built-in temperature compensation for accurate measurements. The sensor features a standard 1¼” NPT connection which you can combine with the BWA-BK-006 bracket and Q45U Wireless Node. This creates an easy-to-mount, IEC IP67, NEMA 6P level monitoring solution.

The K50U when paired with the Q45U wireless node, delivers a turnkey, single-sensor remote monitoring solution that is both rugged and affordable. Therefore it can also function as a component of a much larger, more complex network with Banner’s many wireless sensors and nodes.

Application Compatibility

The sensor is also an ideal solution for a range of applications beyond liquid or chemical tank level monitoring. Applications include pallet presence sensing or monitoring dry material level in a hopper. The K50U is available in two models, with a 1-wire serial interface or a model that functions as a Modbus slave via RS-485. Compatible with a wide range of Banner wireless nodes, the K50U provides reliable sensing for a single sensor application or integrated as part of a multiple sensor, long distance multi-hop network.

The K50U Ultrasonic Sensor works in a variety of environments to provide a measurement of the distance between the target and the sensor. It is designed for plug-and-play use with the Q45U wireless node, creating a cost-effective and easy-to-use solution for monitoring mobile or remote tanks and totes.
