EN010 Series Eddy Current Sensor

     The eddy current sensor is the optimal sensor for measuring the radial vibration and axial displacement of rotating machinery and is widely used for non-contact measurement of many rotating machinery including steam turbines, gas turbines, water turbines, compressors, fans, centrifugal blowers, etc. The ENVADA eddy current sensor uses an innovative linear extension technique that requires only three probes of Φ8, Φ11,Φ25 made in ENVADA. These can replace more than 10 instruments of other designs to meet various application requirements.

 
Function Characteristics

  Includes standard eddy current displacement sensor.

  Completely sealed design with the head made in high temperature capability and low expansion PPS injection moulding.

  Optimised design of temperature stability for the coil parameter and very low temperature drift.

  High quality connecting cable and stainless steel connector.

  High reliability mechanical connection with excellent anti-pull and anti-distortion performance.
