KE NaK filled Melt pressure transmitters

Description

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. The K Series utilizes standard melt pressure principles and construction; 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.

Application:

  • As for FDA approval,   K series is suitable for Mercury free , food and medical application
  • Processing   special polymers, technopolymers (538 °C /1000 °F)
  • Pressure ranges from: 0-35 to 0-1000 bar / 0-500 to 0-15000 psi
  • Accuracy: < ±0.25% FSO (H); < ±0.5% FSO (M)
  • Hydraulic transmission system for pressure signal guarantees stability at working temperature (NaK). Liquid conforming to RoHS Directive. NaK is defined as a safe substance (GRAS)
