Description

Sonar Piston Hydrophone – Order Code ML4X50

The ML4X50 is a circular plane piston, immersion hydrophone for measurements in the frequency range 100kHz to 1MHz. 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.
