Structure-borne sound and temperature sensor BS20
The structure-borne sound sensor BS20 with
exchangeable attachments is used in connection with the
SONAPHONE for applications including:
•
Condition monitoring of machines, systems and plant
components
•
Function checking of steam traps and valves
•
Monitoring of wear and malfunctions in rolling or slide
bearings, for example
•
Monitoring of lubrication conditions
The acoustic playback volume can be adjusted using the function buttons. Testing can be started
and stopped in the same way. The integrated temperature sensor improves the evaluation
reliability of the test data for a wide range of different test sequences, such as tests on steam traps.
