Spherical Hydrophone

Type 8105 is a robust spherical hydrophone usable down to 1000 m ocean depth with excellent directional characteristics.

USE SCENARIOS

• Calibration reference standards 
• Ultrasonic measurements in liquids 
• Cavitation measurements 
• Laboratory and industrial measurements in liquids and gases 
• As underwater projectors (8103, 8104 and 8105) 
• Noise measurements in humid and polluted atmospheres

A small, spherical transducer for making absolute sound measurements over the frequency range 0.1Hz to 160 kHz with a receiving sensitivity of −205 dB re 1V/μPa. It is rugged, being capable of withstanding pressures of up to 107 Pa (100 atm.; 1000 m (3250 ft.) ocean depth).

This hydrophone has excellent directional characteristics: at 100 kHz, it is omnidirectional over 360° in the x-y (radial) plane and 270° in the x-z (axial) plane.
