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.
A near incompressible sodium-potassium (i.e. NaK) mixture is used for pressure transmission.
NaK is FDA recognized safe (GRAS) substance.
