The K Series utilizes a near incompressible NaK (Sodium Potassium) for pressure transmission while using standard melt pressure principles and construction.
The K Series strain sensing technology is based on a foil strain
Pressure ranges: 0-35 to 0-1000 bar / 0-500 to 0-150000 psi
Accuracy: < ±0.25% FSO (H); < ±0.5% FSO (M)
The hydraulic transmission system for the pressure signal guarantees stability at operating temperature (NaK). Fluid conforming to the RoHS Directive. NaK is defined as a safe substance (GRAS).
The amount of NaK contained in the models: KN0 series (30mm3) (0.00183 in3) , KN1, KN2, KN3 (40mm3) (0.00244 in3)
