Needle Hydrophone NH0200 (HP+DCPS)

Product Overview:

      The NH0200 (HP+DCPS) needle hydrophone is a primary standard measurement tool for measuring sound fields and sound pressure, suitable for both continuous wave and pulsed wave measurements. The needle hydrophone has a PVDF film, typically a few micrometers thick, on its needle tip. This film acts as a highly sensitive piezoelectric transducer, converting received sound pressure signals into corresponding voltage signals.

Product Features

1. The needle hydrophone is small in size and does not cause significant interference to the test sound field;
2. Wide range of applications and good directivity;
3. Good sensitivity and high cost-effectiveness;
4. Equipped with a preamplifier and DC coupling for underwater ultrasonic testing.

Technical Parameters

1. Probe sensitivity: 55mV/MPa;
2. Sensitivity variation range: ±3dB;
3. Frequency response: 0.1-40MHz;
4. Sensor material: 9μm thick PVDF;
5. Hydrophone diameter: 0.2mm.
