Pressure gauge PG-30

Pressure gauge PG-30

  • Compact and lightweight general-purpose pressure gauges
    Innovative general-purpose gauges of compact design (30mm sq.) and drip-proof structure (IP65).
  • Clear indication by LED
    Easy-to-see LED assures clear readings on the panel and even in a dark place.
  • Various modes and units can be selected according to applications
    Eight different pressure units
    Three analog output modes
    Eight switch output modes
  • Meet EMC standards
    EN 55011 (EMI)
    EN 61326-1 (EMS)
  • Low consumption by nondisplay mode
  • Set data protection by panel lock function

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 “1” prior to shipment.

ANALOG OUTPUT MODE

  • When shipped from our factory-101R : R mode is set at “1”, 102R : V mode is set at “3” and 103R : G mode is set at “2”.
  • The above 3 types can be set at “1”, “2” or “3”. However, the accuracy at V mode of 103R can’t be guaranteed.

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.
