Protected Element Transducers are used for rough, irregular or hot surface. There are three different types of protective faces. Protected Membrane, Protected Wear Cap, and High Temperature Delay Line. These transducers are available in both G series and S series with either straight or right angle BNC connectors. Lemo connectors may also be available.
Protected Membrane(PM) is designed to improve coupling with the rough-surface test materials.
Protected Wear Cap(PW) prevents the transducers from being damaged by the rough-surface test materials. The cap is replaceable.
High Temperature Delay Line(HDL) is used for hot surface testing. The temperature can be allowed up to 900°F.
