Task and function
Task
The testing equipment VKP 10 is used to test and
analyse steam traps of all types.
The testing equipment consists of a display
device and a sound probe.
Function
The testing equipment measures and analyses
ultrasonic vibrations that occur when steam
flows through functioning steam traps. The ul-
trasonic vibrations are transferred to the tip of
the sensor by pressing the sound probe to the
specified point of reference on the trap body.
The ultrasonic vibrations are then converted
into electric pulses and indicated by the display
device. The test equipment VKP 10 signals only
vibrations within 40 – 60 kHz, as these frequen-
cies constitute the usual vibration range associ-
ated with flowing steam. The user evaluates the
sensed ultrasonic vibrations as part of the com-
parison measurement carried out for reference.
