Overview

A simple switch for a fixed level

A float moves with the liquid and trips sealed reed switches at fixed heights. It is a simple way to get one or more high/low signals without putting a mechanism into the process.

It consists of a guide pipe made from SS 304 / SS 316, a magnetic float of SS 316 that moves on the tube with rise and fall of level. Hermetically sealed reed switches are housed in the guide pipe. The switches can be fixed at any position throughout the length of the pipe; however, the position should be defined at the time of order as it cannot be changed at site.

Since it works on magnetic principle, there is no mechanical connection and hence the chances of any wear, tear or fluid contamination are eliminated.

Set-and-forget accuracy

Factory set accuracy of ±5 mm, with 1, 2, 3 or 4 switching positions fixed in the guide pipe at order.

Sealed switching

Hermetically sealed reed switches inside the guide pipe, with no mechanical linkage into the process.

Day tank duty

Widely used on diesel and furnace oil day tanks, vending machines, pumping stations and water tanks.

Panel-ready

PC, PLC, DCS and alarm annunciator configurable. Use a relay control unit for high resistive or inductive loads.

Features and specification

Switch positions must be defined at the time of order, as they cannot be changed at site. Optional relay units are available for higher current ratings.

Set the switch points before ordering

Share the tank height, medium, required switch points and connection. We will confirm the guide length, float and switch arrangement.
