Piezoelectric film ultrasound transmitters and receivers offer unique advantages for air ranging applications. Resonance frequency and vertical beam directivity of the transmitter and receiver can easily be customized by changing the diameter and length of the PVDF cylinder. Cylindrical PVDF receivers exhibit very wide horizontal or omni-directional beam directivity and broad band characteristics. These characteristics lend unique solutions in many applications such as two-dimensional positioning, digitizer, object detection, and distance measurement. Piezo film ultrasound transducers also have very low resonance "Q" values. This means that the signal rise and decay times are much shorter than conventional ceramic ultrasound transducers, making Piezo film transducers ideal for positioning applications.
For applications that require high ultrasonic power, the CEDRAT Group distributes the Ultrasonic Industrial Processors (UIP) throughout France and Europe, which are ultrasonic Langevin transducers made by Hielscher, a German partner company. Hielscher's wide product range of ultrasonic processors for industry allows for a seamless scale up from lab samples to bench top or prototype units and, most essential, to full industrial scale. The power spectrum for industrial applications reaches from 12 up to 16,000 watts per single processor at one time. These ultrasonic processors have many applications, such as welding, cutting, homogenizing, emulsifying, disintegration or deagglomeration and dispersion in the production process. Due to their high efficiency and low maintenance Hielscher systems are replacing ordinary technologies, such as shear pumps and high pressure homogenizers. For specific industrial applications where an ultrasonic treatment could improve a production process, Cedrat Technologies can provide technical support to help in the integration of Ultrasonic Industrial Processors (UIP).

Ultra-Trak passively monitors ultrasounds produced by operating equipment. It can be readily connected to alarms or recorders for datalogging, thanks to its 4-20 mA current output, coupled with a pure demodulated output.
Housed in stainless steel, the rugged Ultra-Trak 750 is water resistant and dust proof which means it can be externally mounted in some of the most challenging environments. Couple this with an extraordinarily wide dynamic range of 120 dB and sensitivity adjustment, this sensor is ready to meet your most demanding sensing needs.
