Turbine flow sensors with threaded connection / Version for HVAC and industrial

型號:Type VT15
  • Hall effect or Inductive proximity sensor
  • Pressure rating up to 300 bar
  • for medium temperatures up to 150 °C
  • The SIKA turbine flow sensor type VTH15 is used for flow measurement and dosing in water and water mixtures. The sensor is used in many applications, including:

    • monitoring of cooling circuits in machine and plant construction
    • water treatment
    • cleaning processes
    • dosing

    The liquid flowing into the turbine flow sensor is divided into partial jets by the blading. These hit the rotor uniformly from different directions and cause it to rotate. The speed of the rotor is now converted into an electrical pulse signal (frequency): The rotor is equipped with magnets, a Hall effect sensor detects the rotational movement.

    A flow proportional frequency signal (square wave signal) is available. Due to the uniform flow to the bearing, the forces largely cancel each other out and wear is reduced to a minimum. The extremely hard bearing materials, sapphire and hard metal, also guarantee an exceptional service life.
