Compact acoustic detector for water leak detection
Stethophon® 04 is an electronic listening device for recording and amplifying structure-born sound oscillations of whatever kind. The new oscillation sensor ensures undistorted sound reproduction even when the noise is barely audible.
The filter adjusts the sound emission of the device to the hearing properties of the users. At the same time, certain
sounds are noticeably emphasized (e.g. deep-pitched sounds of plastic pipe, high-pitched sounds of steel pipes).
The operator hearing protection function automatically ensures that the headphone is muted when loud noises suddenly arise. To simplify localization, the digital display enables the sound intensity at a number of monitoring points to be objectively compared.
Besides the cable headphones, a wireless version is available including SDR digital radio. The Sewerin Digital Radio (SDR ) offers a sound transmission quality equal or better than by cable. By going without the cable, the comfort of work is improved considerably. Headphones and detector connect automatically by bidirectional radio link when switched on.
Sewerin Digital Radio works over short distances without any loss. Unlike simple analog radio transmissions, the completely digital signal processing does not allow acoustic interference caused by hissing or re-amplifying.
The filter function enables the users to listen to the sound at the frequency that best suits their hearing and the particular noise being listened to. The filters make it easier to hear certain noises such as the deep-pitched sounds typical from leaks in plastic pipes and higher frequencies from metallic pipes.
The hearing protection feature automatically ensures that the headphones are muted when loud noises suddenly arise to protect the operator's hearing.
