GMP™ Delayed Contact Transducers 

GMP Delayed Contact transducers are available in frequencies from 50 kHz up to 500 kHz.  Their ability to be made in low frequencies and large dimensions make them suitable for a wide range of applications. Short replaceable delay lines allow these transducers to be used on rough surfaces, such as concrete, without causing permanent damage to the transducer itself.  All sizes are manufactured with stainless steel housings.
