Sahana Engineering

Principle :

• The Magnetic Level Switch consists of non-abrasive Float carrying permanent magnet and non-ferrous stem carrying one. two or multiple reed switches. The float glides along the stem and when the float nears the vicinity of reed switch the magnetic field of permanent magnet forces the contact to close, thereby completing the external electrical circuit. 

Applications :

• Due to simple design, reliability and with only one moving part i.e., Magnetic Float, it finds application in various liquids where accurate and repeated liquid level control is called for. 
• This type of float switches are suitable for Storage Tanks, Utility Tanks, Process Tanks, Hydraulic Power Pack, Centralised Lubricatio System, Fuel Tanks, Cooling Tower, Textile, Pharmaceuticals and special purpose machines. 

• DC : Din Solenoid Connector made of polymide suitable for indoor small tank mountings 
• WP : Weatherproof made of cast Aluminum suitable for High temperature, Large Tanks and Open environment 
• FP : Flameproof made of Cast Aluminum suitable for Exdl, group II A and 1113 as per IS: 2148
• IP : IP 68 gland & cable for underwater application 
• SP : Special enclosures (Drawing to be provided by customer) 

Features:

• Rigid Design
• Easy Maintenance
• Detects Liquid Levels
• Easy To Operate

A Liquid Conductivity Level Switches uses a probe to read conductivity. The probe has a pair of electrodes and applies alternating current to them.

When a liquid covers the probe its electrodes form a part on an electric circuit, causing current to flow which signals a high or low level.
