Specialized manufacturer of Digital Pressure Meters and Load Cells

VALCOM CO.,LTD.

 

Strain Gauge Panel Meter for Scaling
VWM6A series

If it is combination with pressure sensors and load cells, it is possible to scalling cilibrate by value.

  • Easy-to-view large display of 25mm in character hight.
  • Can be used by AC adapter and AAA alkaline cells.
  • There is two comparator functions, [HL mode] and [5 step sorting mode].
    It is compared to measured mass value and set mass value, it can display the results or have a notice by buzzer.
  • Option Specifications(3 type)
    ●RS-232C interface (Both directions RS-232C)
    ●Analog output 4 to 20mA
    ●Photo Mos relay 3 points + RS-422/485 interface
