Description
The steam trap testing equipment VKP 10 consists of a display device and a sound
probe.
The portable ultrasonic detector VKP 10 is designed for evaluating and testing steam
traps of all makes in order to detect steam losses and leaks.
Function
The testing equipment detects and evaluates ultrasonic vibrations caused by the
media flowing through the steam trap. The ultrasonic 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 VAPOPHONE VKP 10 signals only vibrations
within 40 – 60 kHz, as these frequencies constitute the usual vibration range
associated with flowing steam. The user will evaluate the sensed ultrasonic vibrations
as part of the comparison measurement carried out for reference purposes.
■ Do not use the VAPOPHONE VKP 10 in areas subject to explosion
hazards!
■ The 9 V NiCd storage battery of the display device must only be
replaced by the manufacturer!
■ The sound probe VKPS 10 must only be used for sensing ultrasonic
vibrations at the surface of the steam trap bodies.
