Gefran NAK Filled Melt Pressure Transducers

The K3 Series are pressure sensors for use in high temperature applications where the process temperatures may reach 538°C (1000°F) such as high temperature engineered polymers.
Utilizes standard melt pressure principles and construction, the K Series strain sensing technology is bonded foil strain gage. The uses a near incompressible NAK (Sodium Potassium) for pressure transmission. NaK is FDA recognized safe (GRAS) substance.


  • Processing  special polymers,(538°C /1000°F)
  • As for FDA approval,  K series is suitable for Mercury free , food and medical application
