Stock Code:
SKU: product options

The high resolution fast Gefran 2400 indicator, 96x48 (1/8 DIN) format, for measurement and alarming of pressure (direct and differential), displacement, force, temperature, process variables measured by amplified sensors.

CALCULATION CAPACITY

  • Compare input variables, calculate the engineering unit, calculate flow rates, ratio, etc.
  • Results can be used as process value / alarm setpoint / retransmitted output

TWO CHANNELS FOR MEASUREMENT / WEIGHING

  • Two main inputs let you simultaneously make two rapid acquisitions with a single instrument.
  • The instrument can supply up to 6 load cells in parallel
  • Resolution: 100.000 points

EASY CALIBRATION  

  • Just enter the sensor label data
  • You can always calibrate conventionally by using the menu.
    The sampling valvue (80% standard) can be set for a strain- gauge
