Sunx Digital Pressure Sensor with Auto-reference Function DP3[9 Jun. 2009, 19:45:30]
ûUnaffected 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.
It achieves a 2.5 ms, or less, response time at a high resolution of 1/1,000.
It enables highly accurate sensing with its excellent repeatability and temperature characteristics.
Selection can be made according to mounting method or place of use.
Pressure 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.)
The 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.
