Product description The differential pressure method
Product description
The Leak Tester 3925 - 0050 is a device for pneumatic and thus non-corrosive leak
testing of series production parts, such as fittings, pump housings, cylinder blocks,
vacuum controls, batteries and many more. Its function is based on the differential
pressure method.
The differential pressure method
This method is particularly suitable for use in series production, because it can be easily automated with sufficient accuracy.
The test medium is low cost compressed air. Due to its low viscosity it can pass
through existing porosities and other leak points with sufficient speed. The test does
not generate any dirt. Cleaning and drying as well as corrosion protection measures
are not required. Maintenance of the measuring system is unproblematic. Prerequisite
for this method is the leak tightness of measuring system and testing device.
As already indicated by the name differential pressure method, the pressure difference
in the measuring branch caused by a leak in the specimen is compared with the pressure in the blocked off reference branch.

Time
The testing process consists of three phases:
1. Filling
With the filling and isolating valve open, the testing pressure set on the pressure regu-
lator is applied to reference volume, measuring transducer and specimen The filling
time is determined by the performance of the pressure regulator, the total volume of
the facility including testing and reference volume, the piping resistance and the crosssection of the valves.
2. Stabilizing
This is the phase of pressure and temperature stabilization in the entire system. The
reference volume shown in the illustration – one normally uses a pressure tight original
work piece – serves the purpose of creating the highest possible symmetry level between testing and reference circuits. This enables a reduction of stabilization time, because possibly existing interfering influences affect both circuits of the system and thus
reduce the effect on the measuring result. Empirical values reveal that with volumes
< 5000 ccm a reference volume is normally not needed.
3. Measuring
The actual measuring phase starts after the stabilization time has expired. By closing
the filling and isolation valves the measuring and references branches are separated
from each other. If the specimen has a leak, the pressure in the measuring branch will
drop in comparison to the reference branch. The measuring transducer shows the resulting pressure difference in the measuring value display. If the pressure difference exceeds the preset limit value during the measuring phase, a signal
Reject
will be
submitted and the test stopped.

Product description The differential pressure method
The isolating valve shown in the illustration is an isolating valve which has been specially developed for leak testers from HeMaTech Prüftechnik. The special requirements
for leak testing were already accounted for in the development of the valve.
Due to the symmetric design, both measuring branches are simultaneously isolated
from each other when closing the valve. Volume and pressure differences therefore act
uniformly on both measuring branches, whereby measuring faults are ruled out. By
distinct separation of both measuring circuits, measuring errors caused by leaks in upstream filling valves are reliably prevented. The isolating valve is pneumatically controlled and heating, caused by e.g. the coil of a solenoid valve, is thus avoided.
Leak testing equipment using the differential pressure method is well established in series production. A vast variety of work pieces and assemblies, ranging from ball-point
cartridges to vehicle engine blocks, are reliably tested for leaks.

The pneumatic section of the tester consists of the following main components:
− the pressure control for filling and testing pressure via electronic pressure set-
ting (set up specification by computer) with pressure monitoring by means of
an adjustable tolerance window
− a pneumatically controlled isolating valve, which rules out heating of the valve
− a temperature compensating differential pressure measuring transducer for
testing test volumes up to 5000 ml without reference volume
− a high single-side overload protection (max. 150 bar/g) of the differential
pressure measuring transducer
− an optional leakage simulation with precision needle valve
(flow meter to be connected externally)
− pressure sensors for function monitoring of the pneumatic circuit

Before connecting compressed air/test medium
In case of major pressure fluctuations in the compressed air supply network we rec-
ommend the installation of a pressure switch, which will emit an electrical output signal when the pressure drops. This signal can be used for display/machine shut-down
purposes. Install a filter unit (min 1µm) in the supply line at a safe and well visible location, to ensure the supply of dry, oil free compressed air. Check the service unit at
regular intervals to prevent the device from being soiled by oil. Include the inspection
and changing of filter cartridges in the maintenance plan; this applies also for filters
with automatic condensate drainage.

Connecting compressed air
The supply air connection, for supplying the leak tester with compressed air, is located
on the back of the device. The supply air connection has a G¼" fitting for a 8/6 mm
hose.
The supplied compressed air must be oil free and filtered. Please make sure that the
compressed air to be connected has a constant pressure of approx. 1.5 bar above the
filling or testing pressure (min. 5.0 bar/ü, max. 10 bar/ü, see also pressure table on
back of housing).
Before connecting the air supply make sure, that the compressed air hose is undamaged and will not be kinked or squashed. The hose must be not pressurized free.
After connecting the hose, tighten the spigot nut of the fitting and check for tight fit.
Connecting the test medium (option)
Devices with a test pressure higher than 6 bar are equipped with a separate connec-
tion for the test medium . This also applies for devices, which are to be operated with
a special test medium, such as nitrogen, helium, etc.
The source pressure value can be taken from the table of pressure values on the back
of the device. Before connecting the test medium supply make sure that the hose for
the test medium is undamaged and will not be kinked or squashed. The hose must be
not pressurized.
After connecting the hose, tighten the spigot nut of the fitting and check for tight fit.
Connecting specimen and reference volume
Two fittings G1/8" for 8/6 mm hoses for connection of a specimen and a reference
volume are arranged on the back of the tester. The dimensions of the hose connections may vary in dependence on the version of the device (test volume).
In order to prevent any expansion (breathing), the hose should be of appropriate
strength. A suitable hose (PA-tube) is available from us.
Hose 4/2; max. 45 bar at 20 °C; Order-No. 8082-0354
Hose 6/4; max. 27 bar at 20 °C; Order-No. 8082-0379
Hose 8/6; max. 19 bar at 20 °C; Order-No. 8082-0381
Hose 10/8; max. 15 bar at 20 °C; Order-No. 8082-0382
Make sure that the supply lines to specimen and reference volume are pressure tight.
The lines must be as short as possible. Avoid the use of plug-type fittings, because these could cause leakages in the testing circuit.
If possible, use a pressure tight original specimen as reference volume. With a test
volume < 5 000 ml the connection of a reference volume is not necessary. For thinwalled or elastic specimen the connection of a reference volume may be necessary,
even for small volumes. If you do not connect a reference volume, you must close the
reference volume connection with the blind cap provided for this purpose.
Before connecting the reference volume make sure that the hoses for test medium and
reference volume are undamaged and will not be kinked or squashed.
The hoses should not be pressurized.

the ENTER-key.
The program memorizes the settings made last in each dialog window. When you call
up a dialog window again later, the cursor will be at the position that was changed last.
Using the write protection switch
The possible input in a dialog window depends on the position of the write protection
switch on the tester. If the key switch is in vertical position or is pulled off, the device is
in write protected viewing mode and you can only make a few changes concerning the
selection and appearance of saved data.
When you turn the key to the right, you switch on the input mode, and you can change
saved data or enter new data. In input mode the cursor jumps to the position that was
changed last in the displayed dialog window.
You can always close a dialog window by pressing the ESC-key.
If you have changed data in one of the dialog windows in input mode and turn the
write protection switch to the left, i.e. locking, these data in the dialog window will be
saved. The device acknowledges this saving process with a short audible signal.
Faulty or incorrectly entered data are automatically corrected by the program or replaced by standard parameters specified in the system configuration. In such a case
the user is informed about the changed or replaced data by a warning window.

measured value on measuring value display (Pa)
NOTE!
When parameters were changed, the conversion factor must be determined again.
NOTE!
Edit 0 disables this function.
Volume multiplier:
This value is for the calculation of the conversion of the measuring value to ml/min.
The factor must be 0.0001 … 9.9999. The default value is 1.0000.
To display the leak rate in ml/min the leak tester requires a volume multiplier.
This volume multiplier can be calculated with the following formula:
Rework Limit:
The intervention limit for rework must be 1 … 2000 mbar.
Default value is 100.
Rework ON/OFF
You can switch rework to ON or OFF with the – and + keys.
Default setting is ON.
Reject Limit:
The intervention limit for leaks must be 1 … 2000 mbar.
Default value is 200.
Consecutive reject number:
Here you can specify from which number of test results REJECT in direct consecutive
a fault is present. The limit for consecutive reject must be in the range from 0 … 999.
Default value is 5.
Protocol:
With the keys – and + you can choose the output channel for the test results: OFF, Ser
#1, Ser #2 (option), Ser #1 and Ser #2 (option):
Record start:
Enter the reference curve start point in seconds from 0.00 … 999.99.
Default value is 0.00 sec.
The start point of the reference curve is the point in time from which the reference
curve is recorded, after the leak test has been started.
Record end:
Enter the record end point in seconds from 0.10 … 999.99.
Default value is 3.00 sec.

NOTE!
If you turn the key switch to vertical position while entries are still
missing, an audible signal will sound and the display will show a
warning with the list of the still undefined parameters, into which the
device will automatically enter the standard values.
The end point of the record (reference curve) is the point in time at which recording of
the record is stopped, after the leak test has been started.
EnvelopTolerance:
The value should be 0.5 … 25.0 % and it is the tolerance of the permissible deviation
from the stored reference curve in % of the end value.
EnvelopTolerance ON/OFF:
You can switch enveloping curve tolerance to ON or OFF with the – and + keys.
Default setting is OFF.
EnvelopStart:
Enter the enveloping curve start point in seconds from 0.00 … 999.99.
Default value is 0.00 sec.
The start point of the enveloping curve is the point in time from which the deviation of the
enveloping curve from the reference curve is recorded, after the leak test has been started.
EnvelopEnd:
Enter the enveloping curve end point in seconds from 0.10 … 999.99.
Default value is 3.00 sec.
The end point of the enveloping curve is the point in time at which the evaluation of
the enveloping curve's deviation from the reference curve is stopped, after the leak test
has been started.

Checking the plausibility of inputs
Before the test parameters are written into the RAM memory, all entered parameters
are subjected to a plausibility check:
Rework Limit < Reject Limit.
If the values do not meet the specifications, the program will adjust the corresponding
parameters accordingly and shows this by inverse representation in the display. You
may either correct the parameters, or accept them in the changed form.

Structure of commands
Syntax:
For the query of values:
RegisterName<(Start)Indize>|[-<EndIndize>]|[;<Indize>;<Indize>;…][;CS]<CR>
For the setting of values:
RegisterName<Indize>=<Wert>[;CS]<CR>
or
RegisterName<StartIndize>-<EndIndize>=<Wert>;<Wert>;<Wert>;….[;CS]<CR>
or
RegisterName<Indize>;<Indize>;…=<Wert>;<Wert>;….[;CS]<CR>
Register names generally consist of 3 non-numerical characters.
Register names are accepted in upper and lower case letters.
A register name is always followed by an index, which can also be two-
dimensional. The dimensions are separated by a colon.
If a range is specified for two-dimensional indexes, both the start and the end in-
dex must be specified in two dimensions.
A register sequence must be terminated with <CR> at the latest after 127 characters.
Characters with an ASCII-value of less than 32 will be ignored or, in case of con-
trol characters, interpreted accordingly.
If a format is activated with time monitoring function and a started command se-
quence is not followed by the terminating <CR> at the latest after 100 msec, the
complete sequence will be ignored.
If the format is activated with checksum, only sequences with correct checksum will
be evaluated. The checksum is generated by non-transfer addition of all utilization
data via 8 bit and final formation of the one's complement. For output purposes
the checksum is appended to the utilization data as a two-digit hexadecimal number in form of ASCII-characters, separated by semicolon. For inputs the same format is expected.
Non-existing register sequences are ignored without any feedback (the correct execu-
tion of setting commands can be monitored by querying the corresponding register).
If the <Value> is a string, it will be transmitted in “ “ and, in case of a transfer,
this format is also expected.
There is no monitoring of whether values are inside the permissible range.
The transfer of impermissible values can lead to unexpected reactions of the device!
Parameters with "Read" access can be released for writing, if desired.
