Underwater Locating Device for VDR and S-VDR data protective capsules.
- High degree of corrosion protection
- Intelligent activation
- Long-lasting battery
The PT9 C-Proof is a Seawater-resistant underwater locating device. It is especially designed for the data protective capsules (FRM) of Voyage Data Recorder (VDR/SVDR) systems. It withstands the rough environmental conditions of maritime navigation, high G-shock impact and deep water immersion.
The PT9 C-Proof is a battery-powered device which radiates a pulsed acoustic signal into the surrounding water upon activation by its water-sensitive switch. The beacon operates over a period of 30 days when immersed in fresh or salt water. It is fitted to a data protective capsule by means of a mounting kit.
The PT9 C-Proof has been type-tested under the hardest conditions and in accordance with the relevant standards. The idea of the PT9 C-Proof was to develop an acoustic beacon especially for VDR and S-VDR capsules in maritime navigation. For this purpose, specially selected materials and coatings were used which have proved themselves suitable to withstand the rough environmental conditions on the deck of a ship. Furthermore, the housing and the water-sensitive switches are galvanically coordinated!
In addition to the corrosion-resistant parts such as housing and water-sensitive switch, the PT9 C-Proof is essentially different from conventional acoustic beacons as a result of its intelligent
activation (patent pending). Disruptive factors such as rain, spray, condensation, detergents, etc. are ignored by this smart feature.
- Tested to meet or exceed all SAE AS 8045 requirements
- Location signal as per DIN EN 61996 for maritime navigation
- Approved by the BSH (Federal Maritime and Hydrographic Agency)
- High corrosion-resistance ensures longevity
- Intelligent activation guarantees a high degree of reliability
- No mechanical protection necessary
- Battery easy to exchange
- Individualised special designs
The advantage of this protection against inadvertent triggering is that the number of unintentional activations is reduced to a minimum, thus improving the life of the battery.
There is no need to install additional parts such as, e.g. a water switch. The PT9 C-Proof delivery status is thus “ready for use”. There is no need to assemble or dismantle the beacon for operation, inspection or battery testing. The beacon test can be performed in agreement with and as defined in SAE AS8045. The battery is field replaceable.
Our vast experience in the development of underwater locating systems puts us in the position of being able to develop and make systems that are tailored to your individual requirements.
TAG 2550 TESTER
Ultrasonic Receiver for Underwater Locating Device
Receives ultrasonic signals between 25 and 50 kHz
The TAG 2550 is a smart and small battery operated receiver designed to receive ultrasonic signals with a frequency between 25 and 50 kHz.
The received signals are reproduced visually in the form of a yellow LED and acoustically by means of an integrated loudspeaker. At the same time, the output signals can be represented via the earphone or on a PC screen via a suitable connection cable.
The TAG 2550 is simple to operate and both the visual and acoustic signals are clear and unequivocal.
Simple operation at the touch of a button
For all conventional data protective capsules
Compatible with all common data protective capsules
The PT9 C-Proof is 100% interchangeable with the following types of acoustic beacons: Dukane DK 120, Dukane DKM 120, Teledyne Benthos ELP-362D and RJE ULB-362. Adaptors for other beacons such as DK/DKM 480 and DK140 are available.
