EasyTREK SP-500

  • The new EasyTREK SP-500 series ultrasonic level transmitters are available to order from the end of June.
    The members of the new EasyTREK SP-500 series can be recognised from the more compact size, and the increased maximum measuring distance in the specific price range.

FEATURES :
  • Short description: 4–20 mA current controlled limit switch featuring galvanic isolation also available as an intrinsically safe unit. The value of the input signal will be compared in the unit with the set (taught) value and the state of the galvanically isolated relay changes in accordance with the comparison mode programmed.
  • Functions:
    ■ Limit switch (high or low fail safe)
    ■ ON-OFF control with selectable switching difference
    ■ Monitoring of discontinuity or short-circuit of the cable
