INTRODUCTION

It is normal practice to use two independent machines on each boiler, one incorporating the pump switch or switches and first low- water cut-out alarm switch, the other with either one switch to provide second low- water cut-out and alarm and high-level alarm.

INDUSTRIAL LEVEL CONTROLLERS

Sehgal n Sehgal Industrial level controllers are an all inclusive range of magnetically operated water level controls for Industrial steam Boilers. Sehgal n Sehgal Industrial Level Controllers are designed to meet all the requirements for automatic ON/OFF control of Boiler feed pump, burner cut-off, high and/or low level alarm or any combination of these.

HOW IT WORKS?

A primary magnet is attached to the float rod slides vertically inside a non-magnetic stainless steel centre tube and transmits the movements of the float to a secondary magnet in each switch unit. There are two pairs of contacts which are operated with a snap action and held by repulsion between the secondary magnet and territory magnet in the switch unit assembly.
