Extrusion indicator

The Gefran 2400 W is a highly advanced process indicator with powerful functions. It can be used for very fast processes or those requiring custom linearisation. Peak hold, valley hold, peak-valley or hold functions are remotely selectable. Power supply is 90-260V AC although a low voltage supply version is optional. It has 4 alarms and analog output. Optional versions offer dual inputs for example for DP across a screen.

This indicator is specially suited to Plastic Extrusion Melt Pressure Applications – see Pressure Sensors section for Melt sensors and transmitters.

  • Very fast 2msec response
  • Input-strain gauge, mV, volt and mA – dual input optional
  • Automatic calibration routines for inputs
  • Isolated 4-20mA re-transmit
  • 32 point custom linearisation
  • Remote setpoint, alarms – 4 alarms 2msec response
  • Digital input functions
  • Programmable keys
Main applications: 
  • Extrusion lines and injection presses for plastics
  • Filling machines
  • Food processing plants
  • Pressure measurement and trip points (direct/differential)
  • Position measurement and trip points
  • Variable set points in fast processes and automation in general, with signal retransmission

Gefran 2400 is a fast display and Alarm unit;

Gefran 2500 is a controller for closed loop control of extrusion pressure.
