Page 20: Basic Measurement Principles
The M20-EPS measurement column uses an air to electronic principle to detect and evaluate the fusion strength index of low density expanded thermoplastics. State of the art signal conditioning and processing results in high measurement, stability, repeatability and accuracy. -
Page 21: Calibration Routine
3.2 – Calibration routine The calibration routine must be used periodically, usually before working shifts. A warm up period of 15 minutes is also required before calibration after powering up for the first time, time required for thermal equalization of all internal circuits. Follow the following procedures for system calibration: Place the needle in its resting pad. -
Page 22: Measurement Routine
The measuring head, composed of a handle and the sensor needle, should be handled with extreme care. It has sharp edges and it is a piercing object; When not in use place the needle on its holder pad, located above the external solenoids. M20-EPS User Guide... -
Page 23: Deep Measuring
3.4 – Deep Measuring For application on large workpieces and EPS blocks, AG20 needles are available with lengths between 100 and 1000mm. Picture 8 – AG20 needles for deep measurement The needles allow inspection of the fusion index at different depths, even in blocks with high densities. -
Page 24: Creation Of Guide Holes
After the guide holes have been created, the needle should be inserted freely up to near the measuring point. At this point, the operator should apply slight force to the final perforation of the material (approximately 50mm wall), positioning the needle at the intended measurement point. M20-EPS User Guide... -
Page 25: Statistical Analysis
3.5 – Statistical analysis The M20-EPS column computes and displays in real time statistical information about the sample population acquired from a part. This functionality is very important because allows the user to evaluate the average fusion strength index of a particular part, as well its index standard deviation. -
Page 26: Tolerance Limits
3.6 – Tolerance limits User may set up to 3 process limits in the M20-EPS, defined as upper limit, middle limit and lower limit. The tolerance limits are displayed as fixed points in the bargraph and they define color zones for measurement approval/reproval. -
Page 27: Needle Clean Up And Air Blockage
LCD. To return to normal measurement mode just press any key. As a standard behavior the M20-EPS will automatically block the air flow to the needle if no measurement change occurs during 2 minutes. This functionality can be changed or disabled as required. -
Page 28: Digital I/O Interfaces
To use the RS232 serial interface a standard patch cable must be used. DB9 male DB9 female (attached to the M20-EPS) (attached to the computer) Picture 11 – Standard RS232 patch cord Note: If the computer or data logger have only a DB25 connector input, use a standard DB9 to DB25 adapter. -

Page 32: Digital Parallel Interface
4.2 – Digital parallel interface The M20-EPS features two digital ports, each 10-bit wide, as shown in Picture 12). Both input and output interfaces are photo-coupled, with high immunity to external environment and coupled noise. In Picture 13 an electrical diagram details each interface and connector pins. - Page 33 Picture 14 – M20 output interface – Typical connection to a PLC input port Picture 15 – M20 output interface – Relay connection Picture 16, Picture 17 and Picture 18 show typical application where output signal are applied to the M20 input ports. Picture 16 shows a simple application where a dry contact (push button, relay, limit-switch or other device) is connected to an input interface.
