Task and function
Purpose
The test equipment VKP 41plus is designed for
checking steam traps for steam loss and banking-
up condensate.
The test equipment VKP 41plus Ex is designed for
checking steam traps in explosion-risk areas for
steam loss and banking-up of condensate.
To perform the test you have the following test
options:
Test jobs prepared on the computer: all test
objects that are part of the test job are shown.
Quick check: A test object is created during the
test.
During the test procedure the surface temperature
of the tested steam trap is also measured, which
makes it possible to detect waterlogged steam
traps. In order to do so you have to enter the
service pressure upstream of the test object. The
boiling point associated with this service pressure is
then compared with the temperature reading. If the
measured temperature is below 40 % of the boiling
point, the steam trap is waterlogged and banking
up condensate.
If the test results are affected by noise produced by
other components of the plant you can perform a
foreign noise measurement. This will help you to
test and evaluate the influence of foreign noise on
the test results.
The test objects are selected and the test results
evaluated on the computer. The necessary software
program is part of the scope of supply. For more
information on the program refer to the supplied
software operating manual.
Function
Ultrasonic vibrations are generated when fluid flows
through a steam trap. These ultrasonic vibrations
are sensed by pressing the sensor tip of the hand-
held measuring probe onto the test point of the
steam trap. A thermocouple integrated in the
measuring probe measures the temperature
simultaneously.
The measuring probe then translates the readings
into digital signals. These signals are then
transferred to the Com Box via the firmly attached
cable. The Com Box then transfers the readings to
the data collector via Bluetooth. The data collector
records the data and displays the readings visually.
If the data collector is used in areas where a
potentially explosive atmosphere is present use the
supplied USB data cable with safety box to connect
the data collector to a computer.
If the data collector is not used in potentially
explosive areas you can use an ordinary USB cable
to connect it to a computer.
The test readings can then be transferred to a data
base on the computer.
The evaluation of the test results is based on limit
sound values (LV). These reference sound values
have been ascertained empirically by the
manufacturer.
A steam trap is operating correctly if all the
following requirements are met:
at least one of the readings is below the
threshold value (TV) and
the measured temperature is 40 % above the
set point
A steam trap is also operating correctly if all the
following requirements are met:
some readings are above the threshold value
and
the mean value of all readings of the test does
not reach the limit sound value
the measured temperature is 40 % above the
set point
If this is not the case the steam trap is either faulty
or the test was affected by foreign noise. To detect
any foreign noises you should perform a foreign
noise measurement. In this case you will be asked

13
to do so in the menu of the data collector once the
test has been finished.
For thermodynamic steam traps a certain limit
frequency of operations is used to evaluate its
performance.
If you did not enter the service pressure,
the equipment will only check whether the
temperature exceeds 40
°C. In this case
banking
-up of condensate will not be
indicated.
For more information on how the readings are
evaluated and interpreted see the operating
instructions for the PC software program.

check.
This procedure is more time consuming than using
pre-defined test objects. You should therefore use
the quick check option only in exceptional cases.
We recommend quick checks only in the following
cases:
To add test objects that are not yet defined in
the data base
To repeat tests several times for a more
accurate identification of a faulty trap
Perform the quick check as described on page
26.
Note all necessary data of the test object.
You will find a template in the file "Data
records.doc" under
"Programs/GESTRA/TRAPTtest_VKP" on your
computer.
After the test touch the "Save" button.
Write down the indicated storage number.
The test result is stored under the test job "9999".
This test job is not allocated to any company.
To assign the quick check test results to a
company in the data base on the computer
follow the instructions given in the operating
manual for the PC software program.
Transferring data between the data collector
and computer
The TRAPtest program uses the developer
setting "USB debugging" of the data
collector. The developer settings must
therefore remain enabled.
When you transfer data for the first time
the opt
ion "USB debugging" is shown.

To enable data transfer, touch the "OK"
button.
To transfer data between the data collector and the
computer, do the following:
Start the PC program on your computer.
Switch on the data collector.
Select the TRAPtest program on the data
collector.
Use the supplied USB cable to connect the data
collector to the computer.
If the data link between the data collector and
the computer is active, the "Data transfer"
button is enabled.
Touch the "Data transfer" button on the data
collector.
The display of the data collector shows a data
transfer message.
To return to the main menu, touch the "Exit"
button.

Selecting test object on data collector
With the aid of the menu item "Test job" you can
check steam traps for loss of live steam. For this
purpose first you have to create test jobs on your
computer and download them to the data collector.
The data collector must have a Bluetooth
connection to the respective Com box.
You can also perform ad hoc tests without
h
aving to create test jobs beforehand. For
this purpose open the menu item "Quick
Check". For more information see page
26.
Open the TRAPtest program.
Touch the "Test Job" button.
A list of all specified test jobs appears. For each
test job the serial number, the name of the plant
and the name of the plant section are indicated.
To select a test job touch the respective test job.
The following information on the selected test job
will be shown:
Serial no. of test job
Name of the plant
Name of the plant section
Number of steam traps per test job
For each steam trap in a test job the following
additional information is given:
Place of installation
Type designation
The steam traps of a test job that have already been
tested are ticked off with a green check mark.
These steam traps cannot be tested again within
this test job. For these steam traps only the test
results are shown. The buttons for other functions
are deactivated.
Once the test job is completed, the
respective number will be highlighted in
green.
To select a steam trap, touch the respective
entry.
If a steam trap has not yet been tested the
submenu "Test" opens. The display shows the
message "...waiting for VKPS data". You can either
start a test or enter a comment.

Checking steam trap
DANGER
Risk of explosion if the pipeline to be
tested is carrying voltage.

Before starting the test make sure that
no part of the pipeline is carrying
voltage.
You can achieve this e.g. by earthing the pipeline.

20
DANGER
Risk of explosion due to spark
-over.

Do not use any items in the explosion-
risk area that could generate sparks.

Do not use the supplied file!
Select a steam trap as test object as described
on page 19.
Make sure that the test point is not covered by
paint or dirt.
Be sure to use the same test point that you used
for the last tests.
If necessary, mark the test point on the steam
trap.
The identification tags help allocating the test
objects to the respective data in the data collector.
You can order more identification tags (stock code
number 389315) from the manufacturer.
Attention!
If the measuring
probe does not touch the
trap firmly at the right position and angle
the readings may be incorrect.

Make sure the sensor tip of the
measuring probe touches only a bare
metallic surface.

Make sure the sensor tip touches
always the same test point.

Make sure the sensor tip is
perpendicular to the surface of the
steam trap when it touches the test
point.
