KD DP404 CAN OPEN digital output

KD

Overview

  • The KD 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.
  • 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, the K series is suitable for Mercury-free, food, and medical application
  • Processing special polymers, technopolymers (538°C /1000°F)
