TECHNICAL DATA
Extrusion processes require very high temperatures. Extrusion pressure can be checked by means of espe-
cially designed transducers.
The IMPACT series sensors are suitable for pressure measurements with high temperature and are based
on the piezoresistive technology.
Following advice for extending the sensors lifetime.
a) Avoid shocks and abrasions to the in contact diaphragm. Protect the transducer with its cover each time
you remove it from its seat.
b) The seat must be prepared perfectly and with appropriate tools in order to respect the depth and axiality
of the holes and tapping.
Pay particular attention to the coaxiality of the holes to the thread, because diaxialities greater than 0.2 mm
will break the transducer during assembly.
It is essential that hole depth guarantee the absence of chambers or air pockets in which extrusion material
may be trapped.
To prevent contact with the extrusion screw or with tools used to clean the extrusion chamber, the front
diaphragm must not extend from the inner wall of the extruder.
c) Before assembling the transducer in machines already in operation, make sure that the housing is clean.
Remove any residual with the suitable cleaning device.
d) The transducer should be removed only with the machine empty (without pressure) but still hot.
e) The transducer should be cleaned with solvents for the material being processed.
Any mechanical action on the contact diaphragm modifies its operation and could break it.
The installation seat has to be realized:
Incorrect working or shape of the side can result in properties out of specification, bad behaviour
or damage to the sensor.
The side should be clean and without any polymer residual.

Drilling kit
A drilling kit with formed tools for drilling, reaming and tapping is available to facilitate correct preparation of
the assembly seat. The assembly seat must be perfect to assure proper transducer function and long lifetime.
Drilling kits are available in the following versions: KF12, KF18.
Drilling procedure
1) To drill hole (D4) up to a distance from the hole equal to the sum of (A+B+C) (tool 3).
2) Make the pass through hole (D2) by the tool 1.
3) To create the seal seat at a distance from the hole equal to dimension (A) (tool 4).
4) With a roughing tap, create threading 1/2-20UNF-2B (recognizable from the greater number of threads
beveled at the mouth) (tool 5).
5) With a finishing tap, go over threading 1/2-20UNF-2B up to a distance from the bottom equal to the sum
of (A+B) (tool 6).
6) To ream the hole (D2) with reamer (tool 2).
Installation seat check
The dimensions of the assembly seat have to be checked after preparation and before the transducer
installation.
Use dummy plug SC 12/18 as follows:
1) Coat the end of the rod with the appropriate ink.
2) Lubricate the threaded part to prevent friction.
3) Insert the dummy plug and screw it fully down.
4) Remove the rod and examine it.
With the exception of 45° surfaces, the ink should be intact on the entire surface.

TRANSDUCER INSTALLATION
Installation procedure
1) Make sure the drilling procedure has been realized correctly. If the sensor is installed in a previously used
hole, make sure the hole is completely clean and free of any plastic residual.
2) Remove the protective cap from the sensor top.
3) Lubrificate the thread with non-grip grease such as Neverseez (Bostik), or C5A (Felpro), or equivalent.
4) Insert firmly the sensor into the hole, first by hand and then with a wrench, 1/4 turn at a time.
Recommended torque: 40 Nm.
NOTE: Please pay particular attention to the sensor installation when it’s provided in its fixed mechanis con-
figuration.
In this case, during the clamping phase any misalignment. Has tube avoided, otherwise a possible interferen-
ce of the sensor mechanical coupling can occur.
Removal (Figure 1)
To remove the transducer from its seat and carry on the working process, dummy plugs with identical mecha-
nical dimensions are available.
The dummy plugs differ by type of threading; max pressure range is 2000 bar for all rods.
The dummy plugs are available in the following versions: SC12 1/2-20UNF seat - SC18 M18x1,5 seat
Brackets (Figure 2)
Models with flexible sheaths require the housing precise fixing. Suitable fastening brackets (SF18) are recom-
mended.
Remember that the fastening point must be vibration-free (vibrations affect the measurement) and that tem-
peratures must not exceed the maximum temperature range for the strain gauge housing (as stated on the
sensor technical sheet).
Extruder starting
Bring the system to working temperature with the transducer installed and without any pressure applied.
Wait until all the material is at the same temperature to prevent the transducer damage by semi-solid material.
Seat cleaning & Cleaning tool
As mentioned in the notes, the seat must be cleaned before the transducer installation.
The cleaning tool is a hard metal cutting tool specially designed to remove working materials residuals.
Recommended procedure (Figure 3)
The following procedure must be implemented with the material in a fluid condition.
1) Insert the tool in the seat and screw down the cutting rod (normally a 1/4 turn at a time).
2) Turn the pilot cutter clockwise until there is no resistance to cutting.
3) Repeat the procedure until the seat is completely clean.
For constructive reasons, the maximum torque applicable to the cutter is 15 Nm (1.5 Kgm).
If the hole occlusion requires higher torque for removal, use the drilling kit and follow the recommended
procedure.
The cleaning tool is available in the following versions: CT12 1/2-20UNF seat - CT18 M18x1,5 seat.

3c - Connecting amplifier (only for modular versions)
Fix the flexible sheath to the machine. Take care not to fix the sheath to parts heated at over than
220°C.
Screw the electrical cable connector to the electronics and switch on the sensor.
Wait 60 seconds before starting to operate the transducer.
To disconnect the electronics from the primary sensor, take care to handle the two connectors next to the
red points and not to force the disconnection.
The electronics must be connected to the primary part by aligning the 2 red points on each connector.
Take care not to force the connectors together: check the correct aligning of the 2 red points.
Remark:
In modular versions the decoupling between the electronics and the primary element is not
allowed.

3d - Wiring and calibration
Connections
The sensors have to be connected as shown in the diagram on the next page.
To obtain a higher immunity from field noise, connect the cable shield to the female connector case on sen-
sor side.
Calibration procedure
Bring the system to the working temperature with the transducer installed and connected to the measure-
ment instrument without any pressure applied.
The measurement chain connected to the transducer is calibrated as follows:
1) To reset the offset on the instrument by eliminating the thermal drift with the autozero function. With the
sensor installed and the extruder at working temperature, wait until the temperature itself is stable, with
a possible variation of +/- 1°C. Consequently Autozero can be activated.
This delay gives the system time to recognize and compensate all the signal drifts caused by tightening
and temperature.
Additional Autozero activations could be run once the temperature stability is reached, with +/- 1°C of
possible variation.
2) Calibrate the instrument and have it display the calibration value shown on the transducer data plate
(80% of full scale). With the external autozero function the calibration procedure is not feasible.
3) If the instrument does not exactly indicate zero, repeat points 1) and 2).
In this way, the instrument is calibrated to give the exact indication in the chosen engineering unit.

3f - Maintenance
Melt pressure sensors must be installed and electrically connected by trained people, following all applica-
ble recommendations, with zero pressure and voltage, and with the machine switched off.
The sensor must be removed with the plastic in melt state and the machine in hot conditions.
Always remove the sensor before cleaning the machine, using steel brushes or similar tools.
Always wear protective gloves and always take adequate ESD precautions to prevent electrostatic dischar-
ges that could damage the sensor.
Always use the wrench for the hexagonal nut when installing and removing the sensor.
DO NOT force the electronics housing.
Once the sensor is removed, clean it gently with a soft cloth while the material is still malleable.
3g - Transport, storage and disposal
The melt pressure sensors Impact series are realized with piezoresistive silicon technology completely “fluid
free”.
Even if these are designed with a thick diaphragm, they must be always transported and stocked with the
protection cap and with the package.
Gefran allows melt pressure sensors of own production, also defective units or damage by the use, for the
disposal.

4a - Autozero function
4. ELECTRONIC FEATURES AND PROCEDURES
The transmitter remains on the standard operating mode, till an external event happens.
The possible channels to activate the additional functions are the following:
- Pin CAL
- Magnetic pen
The operating manual explains the following features:
1) Autozero
2) Calibration (CAL)
3) Total Reset
The following pages explain the application modality, for all the additional functions.
The contents are related to application limits and aims.
1) Autozero
Application mode Limits Result
The Autozero function is activated by:
1) Positioning the magnet near the
Autozero label on the shell of the
sensor.
2) Short-circuiting the correct pins
(e.g. pins E-F for the 6 pin connec-
tor) for the external Autozero ver-
sion.
The magnet has to be maintained on
the Autozero position for a time within
2 to 5 seconds.
± 40% F.S. The Autozero effect will be visible
after waiting 2 seconds after the start
of the function.
The precision of the zero value will be
defined by the accuracy class of the
sensor.
NOTE:
During the Autozero phase, the current output for the IE/IX transmitter series, can increase up to 7 mA.
That’s a short variation only visible during the Autozero phase; it won’t have any effects on the final signal.
ACTIVATION OF AUTOZERO AFTER THE FIRST INSTALLATION
The Autozero function makes it much easier to run calibrations after the first installation.
With the sensor installed and with the extruder at work temperature, wait 1 minute before running Autozero.
This delay gives the system time to recognize and compensate all of the signal drifts caused by tightening and tempe-
rature.
If the transmitter is kept powered, additional Autozero activations can be run immediately; on the other hand, you will
have to wait 1 minute each time the system is switched on again.
1) Machine pressure = 0 bar and transducer
powered
2) Put magnetic pointer on marked spot
(2...5 seconds)
3) Remove magnetic pointer
4) Ready !

2) CAlibrAtion (CAl)
Application mode Limits Result
Start CAL:
The Calibration function is
activated by short-circuiting the
pin E – F for a minimum time of
1 second.
Stop CAL:
Release the E - F short-circuit.
The whole Zero unbalancement in
comparison to the zero done by the
manufacturer, has to be ± 20%FS.
During the Calibration phase the
signal will be unbalanced to the
80% FS.
The calibration effect is visible 2
seconds after short-circuiting E - F.
The Calibration function doesn’t work
outside the defined limits.
NOTE:
The Calibration function is not allowed for “external Autozero” version.
3) totAl reset of the CAlibrAtion vAlues
4b - NE21 and NE43 compatibility specifications (for series IX - IE - I7 )
The IX - IE and I7 series are fully compatible with the NE21 Namur recommendation.
The same compatibility is valid for the NE43 Namur recommendation with the following sensor behaviour in case of
breakdown:
• Cutcable:breakdowninformationasthesignalis≤3,6mA
• Devicenotconnected:breakdowninformationasthesignalis≤3,6mA
• Brokenpower-supply:breakdowninformationasthesignalis≤3,6mAorincaseofperformanceproblems
• Most common failures on primary sensors: the signal goes to 23 mA (e.g. due to overpressure)
NOTE: in all the remaining situations, the output signal is always included between 3,6 and 21 mA.
Recommendation: the error level set by the customer (e.g. maximum pressure value) has to be inside the
sensor nominal range.
5. AUTOCOMPENSATION EFFECT ON IMPACT SERIES
Impact series sensors work on a piezoresistive principle by a silicon chip. All the components need about an accurate
thermal compensation either of the zero signal or of the span signal.
This compensation eliminates the sensor drift effects and is realized by the temperature signal digital reading through
the silicon chip.
The components thermal inertia can generate signal over/under elongations (<15% FSO) during fast thermal gradients.
In steady state the signal is correctly compensated.
Application mode Limits Result
The Autozero fuction can be activated
in the following ways:
1) Magnet has to be maintained on
the Autozero position for a time of
20 to 25 seconds.
2) Short-circuiting the correct pins
(e.g. pins E-F for the 6 pin connec-
tor) for a time of 20 to 25 seconds,
for the external Autozero version.
The Zero and Span of the transmitter
will be recalibrated to the factory
settings.
NOTE:
During the total reset phase, the current output for the IE/IX transmitter series, can increase up to 7 mA.
