Round type Color Bar Graph Meter "RAINBAR" series
RBC series

  • Display changes among red, orange and green, intuitively easy to see.
  • High accuracy thanks to the split-mounted 101-dot LED.
  • Easy-to-view color bar graph instead of digital display.
  • Supports various signal inputs for wide range of use.
  • Compact, low-cost, high brightness and easy-to-view design.
Input signal Specify among 1 to 5V, 4 to 20mA(4-wire, 2-wire), 0 to 5V, 0 to 10V.
Sensor specifications Select from Pressure Sensor Analog output type or output devices above.
Use Thermometer, pressure meter, load meter, level meter, flowmeter, tachometer, etc.
