 Gefran is  the worlds largest suppliers of extrusion pressure transducers and transmitters for OEM machine supply and replacement. They offer a series of special variants to resolve specification issues. In addition Gefran has released some new technologies, such as the NaK series which are new technology and solve many of the application issues we face today.

  • Ranges from 30 to 1000 bar– temperatures to 400°C with standard diaphragm
  • Low temperature induced drift [optional auto compensation on analog outputs]
  • NaK is defined as a safe substance [GRAS]
  • Accuracy 0.25% or 0.5%[standard]
  • Outputs 3.3 mV/V or 4-20mA [KE series]
  • Inconel 718 diaphragm GTP coating to 538C
  • 1/2 – 20 UNF or M18x1.5 standard process connection
  • Standard 6 PIN bendix connector  – cable not included
  • 32 series is standard with J thermocouple K is optional at no charge
