APPARATUS FOR MEASURING ULTRASONIC POWER |
摘要 |
An ultrasonic power meter is provided for measuring ultrasonic power emitted by a device (18) under test. The meter includes a casing forming a chamber (16) within which an ultrasonic absorber (14) formed from polyurethane material is located. Overlying the absorber (14) is a membrane (12) of polyvinylidene fluoride which acts as a pyroelectric detector. The meter also includes a transfer medium (10), typically water, for allowing the transfer of ultrasonic energy emitted from a device (18) under test to the meter.
