Strain Gauge Color Panel Meter VALCOR series
F4/F5 series
Extraordinary performance in the fields of coating and wastewater.
F4/F5 shows differential pressure between two input channels on the main display.
Various setting outputs make it more useful.
- Current operation state (normal/abnormal) can be found easily by the color of the value (on main display).
- Measured values can be displayed in 3 colors: red, orange and green, as desired, in areas partitioned by set values.
- High speed sampling as fast as 1000 samples per second.
- Fast output enables use for high-speed and safe control purposes.
- Analog output ranges of 4 to 20 mA, 1 to 5 V and 0 to 5 V included as standard.
- Output scaling function included, which allows the measurement range to be set variable as desired.
