While working with acoustic sensor without removable elements for handling, use the handle
on sensor cable to position the sensor (pos.9) .
Using of magnet allows to attach the acoustic sensor to metal pipes and isolation valves. While
preparing the sensor for the operation with removable handle and (or) rods, these plugs should
be removed. After finishing the location the accessories should be removed and the plugs should
be placed back.
3.2. Structural and operation features of acoustic sensor
Sensitive element of acoustic sensor is placed on steel sensing base (later on – base). The
base is hanging at snap diaphragm made of sound-proof rubber and protected from external
noise with safety cuff. Overall design of the sensor reduces the distortion of external noise and
prevents mechanical damage of body.
Best protection from external noise is provided when cuff is placed fully on ground surface.
(also when using rods).
When working with sensor, the cuff is placed fully against the surface, and the base of sensor
should touch the ground surface.
