Incorporates Auto-reference Function 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, judgement 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.Example of air-leak testThreshold level

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. In case of DP3...operation efficiency UP! Since the threshold level can be automatically changed by the auto-reference function, two suction nozzles can be used, alternately, with one sensor.DP3-80Threshold level for suction nozzle for trimmersMODE

Two Outputs with Four Independent Settings and Four Output Modes Enable Control as per Your Requirement1 Hysteresis mode The hysteresis of the comparative outputs can be set, as desired, with the set values. 2 Window comparator mode The comparative outputs can be made ON or OFF by a pressure within the set range. Since Comparative Output 1 can be used as a self-diagnosis output, it is possible to specify the auto-reference input range.Hysteresis Hysteresis Comparative ON Output 1 OFF ON Comparative Output 2 OFF (Note) 0

High Accuracy High Resolution High SpeedIt achieves a 2.5ms, or less, response time at a high resolution of 1/1,000. It enables highly accurate sensing with its excellent repeatability and temperature characteristics.

Note: The auto-reference function acts only on Set Value 3 (P3) and Set Value 4 (P4) of Comparative Output 2.Optimum for leak test Leak test mode This mode is optimally suitable for a leak test since Comparative Output 1 can be set to the hysteresis mode and Comparative Output 2 can be set to the window comparator mode.

Forced output mode Suitable for start-up check The comparative outputs are forcibly maintained in the OFF state in the sensing mode, irrespective of the set values. Also, since the comparative outputs can be forcibly made ON or OFF with key operation, without actually applying pressure, this mode is suitable for an operation check or a start-up check.4PressMODE

Direct mounting on a wall

The sensor can be mounted on the suction head of a chip mounter.

Analog Bar DisplayPressure changes can also be displayed in an analog fashion using LED bars. Hence, sudden pressure changes can be recognized at a glance. LED bars indicate the pressure level in steps of 10% F.S., regardless of the pressure unit.

Peak Hold/Bottom Hold DisplayThe peak value or the bottom value of the varying pressure can be displayed. This function is convenient for finding the pressure variation range or for determining a reference for pressure settings.

Selection from Six Pressure UnitsThe pressure unit can be selected from six different systems to suit your requirement. The selectable pressure units differ with the sensor type. When the pressure unit is changed, the measured pressure value and the set values are automatically converted.

DP3APPLICATIONSConfirmation 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 70g. 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 DP3-8010 0k Pa
