Reed 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 top of a liquid storage tank and is used for detecting critical overfill conditions for high level alarm, monitoring, and control applications. The HLTFD provides support for Normally Open (NO) or Normally Closed (NC) output type and supports inductive and capacitive loads.
Explosion-proof Tank Level Switch / Durable 316SS
The H Series HLTFD Float Type Level Switch is certified for use in Zone 0 hazardous locations and is Explosion-proof/Flameproof.
The HLTFD is a simple apparatus and does not require power to operate. The level switch can be ordered with a single or dual actuation switching option along with customizable set points. The stem length is available from 1 ft to 9 ft lengths in 1” increments.
