Piston Hydrophone
A circular plane piston, immersion hydrophone for measurements in the frequency range 100kHz to 1MHz. Code ML4X50.
Overview
The ML4X50 is a circular plane piston, immersion hydrophone for measurements in the frequency range 100 kHz to 1 MHz.
Comprising a four-layer laminate of 50 micron PVdF, the ML4X50 provides flat, broadband sensitivity and directivity patterns that display exceptional correlation with circular plane piston theoretical modelling.
