Audio life detector

Audio Life Detector (2nd Generation)

Brand: Sheng Bolan

Model: BE-20R/2

    An audio life detector is an acoustic detection device designed to detect and locate victims following earthquakes, explosions, and... Landslide Survivors of mine accidents or building collapses who are buried beneath collapsed structures. Life detectors can detect subtle vibrations through specialized sensors. Sensor Detecting these life signals allows for precise localization of those trapped, and the probe boasts high sensitivity.

1. The BE-20R/2 audio life detector searches for and locates victims buried under rubble.

2. The sensitive sensor enables the BE-20R/2 life detector to effectively capture even the faintest sounds and vibrations emitted by victims.

3. The ultra-sensitive seismic wave sensor inside the BE-20R/2 life detector is connected to a walkie-talkie.

4. The BE-20R/2 life detector can automatically adjust itself without requiring pre-setting.

5. The BE-20R/2 life detector is equipped with an adjustable filter that can effectively reduce interference from other equipment at the rescue site.

Suitable for rescue operations in rubble caused by earthquakes, collapses, and building collapses, applicable to... Firefighting Municipal, mine rescue, and other emergency response agencies carry out rescue operations in confined spaces and areas that are difficult to access using conventional methods—such as relaying information on victims trapped in collapsed buildings, deep wells, mines, and other confined spaces; locating missing persons in damaged vehicles, aircraft, ships, and trains—particularly in areas that are hard to see with the naked eye—as well as in sewer lines, mine shafts, and underground locations.

1. Host: With audio waveform frequency display

2. Probe: 2-channel probe equipped with an 8-meter cable, with a gain >110 dB (300,000 times).

3. Probe: Equipped with one voice-intercom probe, enabling communication with trapped individuals.

4. The audio amplifier’s gain for the sound channel is less than 120 dB (1 million times at a signal-to-noise ratio of 4:1). The 50 Hz power-frequency rejection ratio is greater than 40 dB (100 times).

5. Operating temperature: -20℃ to 60℃

6. Storage temperature: -40℃ to 70℃
