KE NAK – Sodium potassium – Output 4…20Ma

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

As for FDA approval, the K series is suitable for Mercury-free, food, and medical application
