High accuracy & resolution
CE Approved
CE : EMC Directive
Due to differential pressure sensing, the pressure can be set with a high resolution of 0.01 kPa.D {1 mmH2O.D} over a pressure range of 0 to 2.00 kPa.D {0 to 204 mmH2O.D} and, moreover, the detection accuracy is within ±1 % F.S.
<Detecting clogging of filter>
The clogging of a filter can be reliably detected by the differential pressure, indicating the time for filter replacement.
Three bright red 7-segment LEDs, 12 mm 0.472 in high, are incorporated in the compact body. They can be clearly read not only in a dark place, but also, in a welllit place. Further, initialization or pressure settings can be easily done with key operation while looking at the display.
(1) Hysteresis mode
The lower threshold value and the upper threshold value establish the hysteresis of the comparative output.
(2) Window comparator mode The comparative outputs can be made ON or OFF by a pressure within the limits set by the upper and the lower threshold levels.
| The pressure unit can be selected from “kPa” and “mmH2O” according to your requirement. Further, during measurement, the pressure unit can be recognized at a glance from the pressure unit indicator. |
 (When the pressure unit is changed, threshold values and the measured pressure value are automatically converted.) |
DP-M2A is incorporated also with the analog current output (4 to 20 mA). Hence, it is ideally suited for real time monitoring and multi-point control in combination with an analog controller (ultra-compact digital panel controller CA2 series).
