The K Series uses standard melt pressure principles and construction; The strain sensing technology is dependent on the foil strain gauge.
A near incompressible sodium-potassium (NaK) mixture is used for pressure transmission.
NaK is an FDA-approved safe (GRAS) substance.
Perfromance Level 'c'
Pressure ranges: 0-35 to 0-1000 bar / 0-500 to 0-15000 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)
