Top Mounted Level Switch
Model No. : MI - 014

Top Mounted Level Switch

INTRODUCTION

The Top Mounted Level Switch is an established and reliable technique in industry for single or multiple liquid level sensing and control in open or pressurized vessels. It offers trouble free service in conductive and non conductive liquids under widely varying temperatures, pressures, liquid viscosity and corrosive conditions. Besides, it provides high repeatability, and effects of shocks or vibrations are minimal.

Side Mounted Magnetic Level Switch
Model No. : MI - 015

Side Mounted Magnetic Level Switch MI 015

INTRODUCTION

The Side Mounted Magnetic Level Switch is an economical free and reliable device used for high, low and intermediate point level switching. It is ideal for tanks with inaccessible tops or bottoms and where insertion depths of top mounted models exceeded

PRINCIPLE

The Side Mounted Magnetic Level Switch has a compact& rugged construction, consisting of a free moving pivoted float assembly and a switch enclosure in non magnetic material to achieve undisturbed magnetic flux. It employs dual magnets, one carried by the float arm and other by the contact carries housed in the switch enclosure. A change in liquid level brings the like poles of dual magnets opposite to each other and resulting repulsion force ensures a changeover of contacts with snap action. The magnetic transmission is glandless, leaving no scope for leakages from vessel into switch housing. These switches are manufactured in various materials, enclosures and special features to suit broad range of media and applications. They are designed to provide high repeatability and to minimise effects of shock, vibration and pressure.

MINI LEVEL SWITCH
Model No. : MI - 016

Mini Level Switch

INTRODUCTION

The Mayur Instruments Mini Level Switches are top mounted as well as side mounted. Top Mounted mini level switches are installed vertically and can be extended through an extension pipe for low level switching or alternatively switch can be side mounted through an elbow. The switch action can be changed from N/O to N/C and vice versa by simply reversing the float direction. The Side Mounted mini level switches are installed horizontally and can be mounted vertically for some applications like flow detection. The switch action can be reversed by reorientation of the mounting.

PRINCIPLE
Top Mounted Mini Level Switch
The Top Mounted Level Switch has a simple & sturdy construction, consisting of a float and guide tube, made of nonmagnetic material to achieve un-disturbed magnetic flux. The float has a magnetic system within it and moves freely along the guide tube, which contains glass encapsulated hermetically sealed reed switches, located at preset positions. Float follows liquid level and magnetically actuates reed switch at preset positions to give a change over contact. Single switching is available through single float depending upon float size and switch construction. It can be mounted vertically from top and can be extended through an extension pipe for low level switching or alternatively switch can be side mounted through an elbow.

Side Mounted Mini Level Switch
The Side Mounted mini level switches are installed horizontally and can be mounted vertically for some applications like flow detection. The switch action can be reversed by reorientation of the mounting. The level switch can be wired directly in series to operate electric loads like audio or alarm, annunciation, mimic indication, which match the low switching capacity of reed contacts. However, high loads like contactor, solenoid or motorized valve should be
connected through a level controller to prevent overloading by surge or inrush current and isolate reed contacts from the electrical power system, to ensure their long life

CABLE FLOAT LEVEL SWITCH
Model No. : MI - 017

Cable Float Level Switch

INTRODUCTION

The Mayur Instruments Cable Float Level Switch is a simple user friendly and reliable switch for liquid level detection. By selecting an appropriate float and cable length, it can be used for small or long range detection of liquids, with or without impurities, sanitary applications like drinking water and also for explosive liquids or liquids in hazardous areas. Beside this by using a number of cable floats with appropriate fixation points, it can be used for multipoint detection

PRINCIPLE
The Cable Float Level Switch consist of a float, integral with a three core electric cable. A fixed micro switch and a moving steel ball are enclosed within the float casing. A change in liquid level causes the float to tilt up or down around a pivot, provided in the form of an adjustable stopper, support pipe or ballast, at an angle and in the process, actuating a steel ball to move and operate a micro switch plunger to close or open an electrical circuit with potential free contacts, to operate auxiliary electrical devices like alarm, pump and solenoid valve..
