水下聲學定位信標是一個圓柱形的物體，一般安裝在黑匣子的外部，船用黑匣子上的搜救定位裝置，是其中重要的部件，當飛機或船舶墜入水中時，信標開始發送人耳聽不到的超音波脈沖，這種脈沖可以被聲納和聲學定位機探測到。通過附近聲納應答接收器，就可接收收到超音波信號，以確定失事飛機或輪船的位置或黑匣子的位置。
The PT-9 C-PROOF Underwater Locating Device is battery-powered.
The PT-9 is activated by immersion into fresh- or salt-water.
1. The capsule for the VDR is mandatory to be positioned on the Antenna Deck. Therefore, the beacon is always in tough environment: salty air, salty water, high as well as low temperatures, which require a special casing to protect the beacon from corrosion. For this, the casing and the water sensitive switches are galvanically aligned.
2. External factors like high waves and heavy rain, causing condensation, are eliminated by the intelligent activation system, allowing the PT-9 beacon to stay alive & working.Therefore, our PT-9 beacon is especially made for the maritime environment!
3. The PT-9 beacon is approved by BSH in Germany and tested against IMO resolution A.861(20)/MSC.163(78) to fulfill IEC61996 and IEC60945.
4. The PT-9 beacon can be used to replac 1:1 the existing beacons in the field:Dukane DK120, Dukane DKM120 and Benthos ELP-362D.AMI 2272B VDR,ACOUSTIC BEACON
