Micro Switch Reliability / Low Maintenance
The Float Type Level Switch by OleumTech is part of the H Series line of high quality instruments delivering unrivaled performance, reliability, and accuracy in the most demanding environments, including hazardous locations.
The float-based level switch is designed to be mounted on the side of a liquid storage tank and is used for detecting either overflow (high) or dry run (low) detection for alarm, monitoring, and control applications.
The HLSFF provides a relay switch output (SPDT) and can operate in either Normally Open (NO) or Normally Closed (NC) mode.
Explosion-proof Float Level Switch / Durable 316SS
The H Series HLSFF Float Type Level Switch is certified for use in Zone 0 hazardous locations and is Explosion-proof / Flameproof.
The HLSFF is a simple apparatus and does not require power to operate. It provides a single actuation point and can be ordered with a custom stem/arm length with a variety of process connection fitting options. Its housing is made of 316 stainless steel while the level switch can be ordered with the 316 or 316L option.
