Description:





The K3 Series are pressure sensors  for use in high temperature applications where the process temperatures may reach 538C (1000F) 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.








Application:






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





Processing  special polymers, technopolymers (538C /1000F)
