Needle Sensors

At ndtXducer® we manufacture miniature needle type sensors for industrial and laboratory use in ultrasonic and acoustic measurements. Sensors can be made with Microdot and Push-Pin connector, or with integral potted coaxial cable. All sensors are handmade, therefor there are always some variations between individual devices.

NM, NP and NC style Needle Sensors

Applications:

Ultrasonic measurements in solids, liquids and gasses.
Calibration of reference standards.
Caviation measurements.
Acoustic field mapping.

Features:

Flat sensitivity and good directivity.
Rugged.
Low cost.
Stable parameters.
Broadband.
Range of aperatures and connection styles available.
Maximum operating temperature 100°
