Application Notes
Level Monitoring for Washdown Environments
Banner’s U-Gage QT50U ultrasonic sensor excels at the most challenging level applications, bouncing sound off any solid surface—even those that may vary in consistency or contrast. The sensor is available with a Teflon-coated transducer cover, making it resistant to harsh chemicals and suitable for the food and beverage industry. Ultrasonic sensors are able to provide accurate monitoring of pump-controlled tanks by sending a continuous signal to measure the current tank depth.
Detecting Pallets with Irregular Loads
An ultrasonic sensor will provide reliable pallet detection. Ultrasonic sensors emit sound waves and “listen” for the return echo of the sound wave bouncing off the target. The sensor can be taught a reliable background, in this case the conveyor, and will listen for sound waves returning from the conveyor. Any object getting between the sensor and the conveyor will be detected, causing the output to switch.
Liquid Level Monitoring
Banner’s U-GAGE QT50U ultrasonic analog long distance sensor has a narrow sensing beam that works in confined areas, such as the tank, without interference from the tank walls and senses with an extended range up to 8 m. The ultrasonic sensor can be mounted to the center so that the beam spreads over the tank to detect the fluid level without interference, while signaling when to pump out excess liquid and pump in additional liquid.
Wireless Monitoring Retrofit in a Pre-Certified Facility
Sure Cross Nodes with FlexPower and Banner U-GAGE QT50U analog sensors quickly and easily facilitate these monitoring requirements without new construction and wiring. The FlexPower Node transmits the sensor data back to the Gateway device. When using a Gateway Pro, data is logged and alerts can be sent when fluid levels reach critical levels.
