Hydrophone projector TD1040

The Colmar TD1040 is a ring-cavity free flooded transducer. A very robust unit typically used for underwater communications. The two main vibration modes have resonant frequencies at 9 and 12 kHz and a usable frequency band between 7 and 16 kHz. Can be used as a receiver in the same band.

Features

• Designed for underwater comunications and telemetry
• Oil filled, rated to full ocean depth
• Robust design suitable for field operation.
• Hemispherical beam pattern, broadband operativity
• Custom interfaces available (cable, connector type, metal to glass pins)
• Customizable in cable lenght and connector type
