A couplant is a material used to couple AE sensors to the surface of the part undergoing monitoring or testing. By filling the microscopic voids on the two surfaces, it maximizes signal transfer to the piezoelectric crystal inside the AE sensor. Ideally, the acoustic impedance of the couplant s..

Physical Acoustics offers a variety of cables for connecting hardware. Signal cables are used for connecting sensors to preamplifiers, and are generally supplied in lengths of 1 or 2 meters. These cables are offered with BNC, Microdot, or SMA connectors on the sensor end, and usually use BNC co..

Physical Acoustics’ magnetic hold downs allow an AE sensor to be mounted temporarily for the duration of a test, or monitoring. The design incorporates a sponge like material that is compressed during installation, providing a small amount of spring force against the sensor to hold it sec..

When a surface’s temperatures exceed those that an AE sensor can tolerate, Physical Acoustics’ waveguides can be used to provide a thermal buffer. By guiding stress waves down a small diameter rod, a sensor can receive signals while mounted safely away from a high temperature surfac..
