Abstract
A level measurement arrangement for measurement of a level of a product in a container comprising: a level sensor, comprising: a conductive probe, a mounting element, comprising, and a process connector, for mounting the mounting element on a ferrule on the container, is described, wherein electrical isolation of the conductive probe from the ferrule is ensured via a dielectric insert, which is inserted in the ferrule, fills all cavities inside the ferrule, and extends through the ferrule into the container.
Claims9
A level measurement arrangement for measurement of a level of a product in a container based on the time of flight needed for electromagnetic pulses to travel down a probe to a surface of the product and its echo to return, comprising:
- a ferrule comprising a tubular stud enclosing an opening of the container, extending from the container and defining a process connector;
- a level sensor, comprising:
- a conductive probe, and a mounting element;
- and
- a dielectric insert, inserted in the ferrule, filling all cavities inside the ferrule, and extending through the ferrule into the container, wherein:
- said mounting element being mounted to said ferrule by said process connector;
- said conductive probe extends from said mounting element through said dielectric insert into the container;
- and
- said dielectric insert being so mounted to thereby insure electrical insulation between said conductive probe and said ferrule.
