  • To compliment our ultrasonic thickness gages we offer a range of ultrasonic transducers. The performance of any ultrasonic thickness gage relies heavily on the transducer and its suitability to the material being measured. Therefore, selecting the right transducer is vital. All Cygnus SINGLE CRYSTAL transducers are made from stainless steel and include replaceable membranes for long life, requiring no zeroing and have a high linear accuracy.
