Technical specifications

Overview

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.

Application:

  • As for FDA approval,  K series is suitable for Mercury free , food and medical application
  • Processing  special polymers, technopolymers (538°C /1000°F)
