Product Description
The dB ultrasonic range of transducers range from 3 m measurement range right up to 50 m measurement range and provide a reliable level, volume, open channel flow, pump control, and differential measurement, within both liquid and solids applications. The sensors benefit from highly accurate and repeatable ultrasonic technology and a low power design with standard interconnecting cables – producing extremely high acoustic power to give exceptionally high results in a wide variety of challenging applications.
The non-contacting design of the transducer means they can be fitted with zero interruption to service, and there’s no time consuming maintenance needed. We offer a wide range of options for our transducer range to suit the application. For example, a shield can be fitted during manufacturing to keep the transducer face clean and dry in applications at risk of submergence, PVDF versions of transducers are available for applications where there are chemicals present, and many more.
All dB Ultrasonic Transducers and dBR Radar Transducers are retrofittable with the Pulsar controller range, so if the needs for your measurement change, your measurement system won’t have to.
