Flexible sensor The sensitivity of the flexible sensor is similar to the sensitivity of the internal ultrasonic sensor. Consequently, its use is also recommended when elements to be controlled are directly accessible. On the other hand, its ergonomics makes easy to check elements difficult to reach or control high densities of pneumatic equipment. The flexible sensor is then the most powerful sensor when facing these kinds of configuration. Consequently, the flexible sensor should be used in complement of the extended distance sensor to pinpoint the leak spot. http://ludeca.com/prod_ultrasound-testing.php For pricing, ordering and additional information, please contact Sales at 951-249-3095 or Request a Quote by using the tab at the top of our home page.
