Page 4: Installation And Positioning On The Machine
INSTALLATION AND POSITIONING ON THE MACHINE 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. - Page 5 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).
- Page 6 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.

However, note that incorrect use will result in an adverse effect. Typical contact protection circuits are given in the table below. Contact protection circuit: Inductive load Voltage Circuit...
- Page 36 Mounting the protective device In the actual circuit, it is necessary to locate the protective device (diode, resistor, capacitor, varistor, etc.) in the immediate vicinity of the load or contact. If located too far away, the effectiveness of the protective device may diminish. As a guide, the distance should be within 50cm.
