Digital Pressure Sensor with Auto-reference Function Digital Auto reference PRESSURE SENSORS High accuracy sensing at all times with autoreference function * Passed the UL 991 Environment Test * UL 61010C-1 compatible, Passed the UL 991 Environment Test based on SEMI S2-0200. [Category applicable for semiconductor manufacturing: TWW2, Process Equipment] [Applicable standards: UL 61010C-1] [Additional test / evaluation standards as per intended use: UL991, SEMI S2-0200] Example of air-leak test Threshold level Auto-reference function follows reference pressure changes Reference pressure • Unaffected by changes in reference pressure By an external signal, the set (threshold) values are corrected by being shifted by an amount equal to the pressure change. Hence, judgment by the sensor is as accurate as before the reference pressure change. This function is extremely suitable in places having intense variations in the reference pressure or where fine settings are required. Reference pressure Before reference pressure change Reference pressure Reference pressure Pressure sensor not incorporating auto-reference function After reference pressure change • Total cost reduction Till now...one sensor was required for each suction nozzle Since the threshold level differs with the suction nozzle, a sensor was required for each suction nozzle, increasing the cost significantly.

Since the threshold level can be automatically changed by the auto-reference function, two suction nozzles can be used, alternately, with one sensor.

PRESSURE SENSORS DP5/DPH Head-separated DP3 APPLICATIONS Confirmation of chip component suction The auto-reference function can compensate for the difference in suction levels due to suction nozzle separation distance. The vacuum type can be mounted close to the chip mounter suction head since it weighs only 70 g. Air-leak test for PET bottles Leak test mode, which is an output mode optimally suitable for an air-leak test, has been incorporated. It can reliably detect even a small air-leak. Because of the auto-reference function, it is safe even if the filling pressure varies. DP3-41...

Setting • If key-protect has been set, make sure to release key-protect before operating the keys. (Please refer to ‘Key-protect function’ on p.817 for the procedure.) • Set Value 1 to 4 (P-1 to P-4) can be made common for all the output modes. • In the positive pressure type sensor, Set Value 2 (P-2) and Set Value 4 (P-4) can be set only towards the high pressure side with respect to Set Value 1 (P-1) and Set Value 3 (P-3), respectively. In the vacuum pressure type sensor, Set Value 2 (P-2) and Set Value 4 (P-4) can be set only towards the high vacuum side with respect to Set Value 1 (P-1)...
