TRANSDUCER

120 kHz Split-beam transducer

Introduction

The ES 120-4x10 is a split-beam transducer with 108

piezo-ceramic elements arranged in four quadrants. The

are wired in parallel. The beam pattern has an elliptic

cross-section suited for horizontal ranging in shallow

waters with the narrow beam in the vertical plane. The
