Direct Measuring Mold Cavity Pressure Sensors, Type 6183A… and 6183AC… 1. General Information Sensor diameter ø1 mm and ø2,5 mm must not be machined Sensor front must be clean and without notches Use only recommended mounting tool Do not pull the sensor out of the hole by pulling on the cable.
Important Hole Conditions 2. Important Hole Conditions The measuring hole can influence the function and life of the sensor. Inaccurate holes can lead to measuring errors due to the inclusion of transverse forces acting on the sensor. Fig. 3: Installed sensor Fig.
Direct Measuring Mold Cavity Pressure Sensors, Type 6183A… and 6183AC… 3. Holes for Sensors The sensor is mounted front flush in the measuring hole in the cavity wall. The pressure in the cavity is transferred via the sensor front directly onto the piezoelectric measuring element, which produces a proportional charge.
Holes for Sensors 3.1.1 Hole for Sensor with Spacer Sleeve Type 6464A1 Use EDM, mill or grind H7 hole in hardened tool steel. Check centering and positional alignment. Fig. 5: Sensor hole for mounting with spacer sleeve; spacer sleeve Hole for Contour-Adapted Sensors This applies to sensor Types 6183AE…, 6183AG…, 6183AX…...
Direct Measuring Mold Cavity Pressure Sensors, Type 6183A… and 6183AC… 3.2.1 Adapting the Sensor Front to a Contour The front of the sensor can be machined with a radius or slanted surface, also when mounted in the mold. However, if the cavity wall is eroded with a mounted sensor, it must be ensured that no liquid enters the connector, for example by sealing the rear sensor body with silicone sealant.
Holes for Sensors Sensors with Chrome-Plated Front This applies to sensor Types 6183AC… The chrome-plated front triples the life of the sensor in the injection molding of glass-reinforced or fiber-reinforced plastics. The front region of the sensor tip is chrome plated for this purpose up to the O-ring and has the same dimen- sions as the unplated sensor.
Direct Measuring Mold Cavity Pressure Sensors, Type 6183A… and 6183AC… 4. Cable Installation and Connectors The cables for piezoelectric sensors must be well insulated. Cables and connectors must be installed with good protection to prevent cable damage during installation and in operation.
Cable Installation and Connectors 4.1.1 Single-Wire Clamping Connector Type 1839 and Mounting Plate Mill a recess for the mounting plate and prepare channel as shown in the drawing. Contact surfaces and threads must be clean and free of grease. Provide radii at transitions and corners in the cable channel or hole, so as to prevent cable damage during assembly and in operation.
Direct Measuring Mold Cavity Pressure Sensors, Type 6183A… and 6183AC… 4.1.2.2 Recess for 8-Channel Connector Type 1710A... Wherever possible, position the cable channel or cable hole in the middle of the recess to simplify connection of the sensors. When space is limited, the cable entry can be located as required, in which a side entry at the level of the base may be used.
Sensor Installation 5. Sensor Installation First install the sensor, then the cable and finally the connector. This sequence is particularly important when installing single-wire sensors, in which the cable in the mold is cut to the required length. All sensor holes and threads must be clean. Use checking tool Art.
Direct Measuring Mold Cavity Pressure Sensors, Type 6183A… and 6183AC… 5.1.2 Mounting Spacer Sleeve and Support Plate Insert the machined spacer sleeve and check before assembly that it is not protruding. Allow a clearance of 0,01 ... 0,03 mm so that the sensor is not pressed against the seat.
Cable and Connector 6. Cable and Connector The most frequent sensor failures are caused by damage to the cable during installation. It is essential to allow suffi- cient slack when installing the cable and the connector. Edges and transitions should thereby be provided with radii and a sufficient length of cable installed to ensure that it is not under strain.
Direct Measuring Mold Cavity Pressure Sensors, Type 6183A… and 6183AC… 6.1.1 Cut and Grip Technique Cut the sensor cable to the required length but do not strip off the insulation. To simplify mold servicing, cut the cable to an adequate length. Slacken the connector at the knurled nut but do not separate it.
Cable and Connector Fig. 13: Installing connector Type 1839 and mounting plate Tapped holes must be clean and free of grease. Secure and install the cover. 6.1.2.2 Installation for Multichannel Connector Types 1708A0 and 1710A0 The recess for the multichannel connector must be clean. When the recess is correctly machined, no contact is possible between...

Identification plate The identification plate contains the type number and serial number of the sensor or the assembly number in the case of the systems and sets for molds with several sensors. Also shown is the sensitivity measured and the average sensitivity in the case of the Unisens ®...
Then check the sensor once more with the cable connected. Any sensor with a too low insulation value should be sent in to the Kistler factory. The local Kistler distributor will provide further information. Contact information is available at www.kistler.com.
The sensor selector on the sensitivity meter Type 5993A is incorrectly set Sensor with particularly high sensitivity A sensor with too low sensitivity should be sent to Kistler for testing and calibration. The local Kistler distributor will provide further information.
Servicing and Repairs 9. Servicing and Repairs Quartz crystal pressure sensors are very low maintenance and do not need to be removed for a mold service or cleaning. Nevertheless, it is advisable to test the insulation and sensitivity of the sensor in its measuring position. The connector part must be dry and clean before connection to an external meter.
The sensor selector on the sensitivity meter Type 5993A is incorrectly set Sensor with particularly high sensitivity A sensor with too low sensitivity should be sent to Kistler for testing and calibration. The local Kistler distributor will provide further information.
Do not overheat the sensor and cable with the hot-air blower. Repairs at Kistler Sensors can be tested and a recalibration performed at Kistler. Repairs and testing at Kistler are arranged through the local distributor. Contact information is available at www.kistler.com 6183A_002-460e-05.10...
Do not discard old electronic instruments in municipal trash. For disposal at end of life, please return this product to an authorized local electronic waste disposal service or contact the nearest Kistler Instrument sales office for return instructions. Page 24...
To assess the cavity pressure, the amplified signal can be processed either via the machine or with an external Kistler monitor. Pressure monitoring allows automated assessment of the molding during production and can be used for good/bad grading.
