INTERNAL ELECTRICAL SCHEMATICS

SELECTION OF DISPLAY MULTIPLIER

  • The last digit/letter represents the selection code : Blinking red LED indicates negative pressure.

  • Diagonal column: Display multiplier cannot be selected due to resolution and number of digits.
  • (Selection code is not indicated either.) Selection code is set at “A” prior to shipment.

ANALOG OUTPUT MODE

  • Selection code is set at “G” prior to shipment

SWITCH OUTPUT MODE

  • Note 1. In the Separate Mode, setting 1 corresponds to SW1, and Setting 2 corresponds to SW2.
  • Note 2. In the Window Comparator Mode, the minimum value for SW1 and SW2 corresponds to Setting 1 and the maximum value corresponds to Setting 2.

OUTLINE DIMENSIONS

Unless otherwise specified tolerance : ± 0.5 (Unit: mm)

 

Others

  • Tube at atmospheric pressure intake
    If there is any possibility that the sensor may become wet with oil or water, which may enter the case through the air intake, connect a silicon tube, or similar, to the intake and position the end of the tube in a suitably safe place. Be sure not to bend the tube or block the end of the tube.
  • Piping
    Use a wrench on a hexagon of fitting part. Do not hold the main body when tightening.
