KD NaK filled Melt pressure transmitters

  • KD NaK filled Melt pressure transmitters


    • The KD Series are 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, but uses a near incompressible NAK(Sodium Potassium) for pressure transmission.
    • The K Series strain sensing technology is bonded foil strain gage.
