Specialized manufacturer of Digital Pressure Meters and Load Cells



Small, Rapid Strain Gauge Panel Meter
VGM2 series

Use in combination with pressure sensors or load cells.

Industry's most compact body full of functions!!

All functions consolidated in a body of 48(W) × 24 (H) mm.

  • Scaling function [Sets the values to be displayed for actual inputs as desired.]
  • Zero shift function [Easy to adjust zero point]
  • Auto AZ function [Sets the initial measurement as zero automatically.]
  • Auto zero function [Measures from the last displayed value as "zero" (Tare)]
  • Tracking zero function [Corrects slow zero-shift internally and automatically.]
  • Auto peak hold function [Switches measurement to the peak hold mode automatically if the preset value is exceeded]
  • Analog output function [Scales the analog output range as desired.]
  • Level comparator function [Compares the level of measurements to output signals]
  • Window comparator function [Compares the measurements between two windows (areas) to output signals.]
  • Control input chattering filter function [Filters chattering to prevent malfunction.]
  • Key lock protection function [Prevents incorrect setting or malfunction due to inadvertent key operations.]

Level Comparator Function

This function compares the measured value with the preset limits and reflects the result of judgment in the S1 output.
It is also possible to add hysteresis to comparison.

Level Comparator Function

Window Comparator Function

This function compares the measured value with the preset windows (areas) and reflects the result of judgment in the S2 output.
Set the higher and lower limits of the window. It is also possible to add hysteresis to comparison.
