Ultrasonic Transducers

Magnetic Transducers are used with magnetic alloys, and consist of a rare earth magnet surrounding a piezo electric crystal which is protected by a wear plate. The diameter used in the description of transducers refers to the nominal diameter of the piezo electric crystal; therefore, the O.D. of a transducer is larger than the crystal diameter due to the annular magnet and transducer housing. Standard transducers can be used on application with contact temperatures of  up to 54°C (130°F). Hi-Temp transducers are available for applications with contact temperatures of up to 175°C (350°F). Special transducers are available for non-magnetic applications.

Magnetic Transducers
This standard style is used with ferrous materials, and consists of a rare earth magnet surrounding the piezo electric transducer. The diameter refers to the nominal diameter of the piezo electric crystal. The annular magnet increases the overall diameter to the value of ‘A’ shown. Temperature range: - 20ºC to + 80ºC ( 0ºF to 180ºF ).

Glue-On Transducers
Allows positive location on non-magnetic fasteners. Also ideal for temporary or permanent monitoring of all joints. Higher repeatability than magnetic transducers because the position of the transducer on the fastener is constant. The cyanoacrylate adhesive acts as a complaint with good sound transmission properties. Operating temperature range is: -20ºC to + 80ºC ( 0ºF to 180ºF ). Transducers are built to order. Please contact Norbar with your requirements.

SMART Glue-On Transducers
These glue-on units have in-built memory and allow both fast and simple monitoring of joints. Simply attach the transducer to special version of the USM-3 and the change in elongation or load since the last inspection can be displayed and recorded. Transducers are built to order. Please contact Norbar with your requirements.
