■ Use VKP 40Ex / VKP 40 only for testing steam traps!
For more information on the test procedure see section “Checking Steam Traps”.
■ Use the equipment only on voltagefree and earthed pipe systems! Mortal danger is imminent if you carry out
measurements on voltagecarrying objects.
■
In explosionrisk areas only the measuring transducer VKPS 40Ex connected via cable with the data collector
VKPN 40Ex may be used.
For more information see section “Safety Notes for VKP 40Ex”!
Description
System description VKP 40Ex, VKP 40
The steam trap testing system consists of the data collector VKPN 40Ex or VKPN 40, the measuring transducer VKPS 40Ex and
the software for data management on the PC. The VKPN 40Ex / VKP 40 can check and evaluate all types and makes of steam traps
for loss of live steam and banking-up of condensate.
The diagnostic system detects and analyses ultrasonic vibrations on the trap body caused by live steam flowing through the stream
trap. The ultrasonic vibration is transmitted through the trap body and picked up by the hand-held probe by pressing the sensor tip
onto a point of the trap body that is characteristic of the respective trap type. The ultrasonic vibration is then converted into electric
pulses and – in the form of digital signals – fed via cable to the data collector VKPN 40Ex or VKPN 40. The display of the data collector
shows the signals received during the test as a standing curve. With this graphical representation one can see at once whether the
tested steam trap is working with or without loss of steam. The recorded ultrasonic vibration is analysed by the data collector and
evaluated in accordance with certain empirically ascertained limit values that depend on the trap type. During the test the temperature
of the steam trap is measured, too. Provided that a service pressure has been specified (on the PC), the diagnostic system identifies
blocked steam traps that cause banking-up of condensate. .
If the annual operating hours and the steam costs have been entered in the system, the software can calculate the financial loss
caused by faulty steam traps. To quantify the steam loss caused by faulty steam traps, empirically obtained test values are used as
reference.
All curves recorded for a steam trap as well as the associated numerical test results and the corresponding analysis by the system can
be stored and printed out.
For more detailed information on the system and its functions refer to the “Online Documentation” of the TRAPtest
PC program.
