Anderson Negele - NSL-F Level Sensor


  • Up to 3000mm length
  • Ideal for adhesive and pasty media
  • Up to 140°C
  • Modular design

Product description

The NSL-F is an innovative level sensor that is based on a modular device platform that offers high flexibility in the assembly of individual sensor components.

In addition to benefitting from the advantages of a building-block system, users of this replacement of the NSK model will also profit from the reliability with which these sensors provide measurements even in strongly adhesive and foaming media. For example, the device will dependably indicate that a tank is empty even in the presence substantial foam. Because of the short response time, highly precise metering processes can be reliably recognised with the NSL-F even in the case of alternating and pasty media.
