K7 PLc NAK – Sodium potassium – Voltage output – PLc

The K7 Performance Level ‘c’ 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 gauge.
A near incompressible sodium-potassium (i.e. NaK) mixture is used for pressure transmission.
NaK is FDA recognized safe (GRAS) substance.

Perfromance Level ‘c’
Pressure ranges from: 0-35 ato 0-1000 bar / 0-500 to 0-150000 psi
Accuracy: < ±0.25% FS (H); < ±0.5% FS (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).
