Liquid Level Sensors Capable of Operating in Harsh Environments up to 200°C

Introduction

High temperature liquid environments have been around for a long time without any accurate, easy method of measuring their liquid levels.  Standex Electronics has solved this problem with their hermetically sealed reed based sensing systems, which allows their float systems to exist in operating temperatures up to 200°C.  Their new liquid level systems can also exist in very harsh liquids as well.  The LS05 series uses a stainless steel housing, offering lengths up to 2 meters, having many switching points, and capable of multiple floats which are ideal when dealing with multiple liquids having different specific gravities…
