Sensor description
2.1 Applications and designated use
The structure-borne sound sensor with exchangeable waveguides is used for applications
including:
Status monitoring of machines, systems and plant components
Function checking of steam traps and valves
Monitoring of wear and malfunctions in bearings
Monitoring of lubrication conditions
2.2 Functioning
The
waveguide
conducts the ultrasonic waves from the test point to the ultrasonic transducer.
The
ultrasonic transducer
converts ultrasonic waves (vibrations) to an electrical signal over a
wide frequency range. This electrical signal is amplified and digitalized within the sensor.
Further data processing and output takes place in the testing device.
The integrated
infrared temperature sensor
allows for contactless and quick recording of the
test object's surface temperature. The size of the visual recording field depends on the distance
between the sensor and the test object.
The
LED lights
act as a torch, making it easier to connect the sensor to test points in poorly lit
environments.
