KE NaK filled Melt pressure transmitters
Data SheetThe 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. The uses a near incompressible NAK (Sodium Potassium) for pressure transmission. NaK is FDA recognized safe (GRAS) substance.
