The KN Series are 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, but uses a near incompressible NAK (Sodium Potassium) for pressure transmission. The K Series strain sensing technology is bonded foil strain gage.
  • Pressure ranges from: 0-35 ato 0-1000 bar / 0-500 to 0-150000 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).
