Description

Applications

  • Marine and shipbuilding
  • Drinking water abstraction desalinization plant
  • Ballast tanks
  • Level measurement in ballast and storage tanks
  • And many more customer-specific applications

Short description
The hydrostatic probe LMK 458H has been developed for measuring level in service and storage tanks and is as a consequence certificated for shipbuilding and offshore applications.

A permissible operating temperature of up to 85 °C and the possibility to use the device in intrinsic safe areas enable to measure the pressure of various fluids under extreme conditions. The basis for the LMK 458H is a capacitive ceramic sensor element, which offers a high over-load resistance and medium compatibility.
