  • Choose from a wide range of software selectable inputs
  • Connect your input device (4-20mA transmitter, loadcell…) directly to the 24V/10V on-board supply
  • Reset maximum/minimum register or "zero" the input via keys on the faceplate
  • Trigger pre-configured functions via remote switch
  • Use the "flash" function to read product and freeze during gaps on continuous production lines
  • For system testing during commissioning use the keys on the faceplate to activate the alarm outputs

Gefran Express (previous versions known as Winstrum software) is a Windows-environment software whose main function is writing or reading all of the parameters of a single instrument via serial connection.

Gefran Express software is supplied in a kit with an interface cable.

One end of the cable has a 9-pole connector that attaches to the RS232 port of any PC; the other end has a 3-pin connector that attaches to the instrument.

At the serial communication level, Gefran Express lets you choose CENCAL (proprietary) and MODBUS protocols, baud rate, parity, and the serial communication port.

You can configure or analyze one instrument at a time, even if it is part of a network.

Other Gefran Express (Winstrum) functions:
  • Storage of configurations (formulas) and rapid duplication
  • Running of a trend to monitor the progress of a maximum of 5 variables, with easy setting of scales and time base on the graph to be obtained
  • Printout of the graph
  • Storage of trend data, with settable time base, in a file loadable by Excel to perform all mathematical or graphic processing required
  • Graphic display of custom linearizations
  • Link from each parameter to on-line help accessible with a double click in the window of the parameter
