Level Switches & Panel ....................................................................................................................................

Side Mounted Level Switch

Level switches are suitable for fitting into tanks and pressure vessels for indicatiing and or controling the level under atmospheric,
vaccum and pressure conditions, Magnetic switches are snap action and glandless and eliminates any chance of leakage. These are suitable
for temperatures upto 400 degree centigrade and pressure upto 40 kg per cm2 Switch is magneticaily operated and is of micro,Mercury or air
vaive type. Material of construction is of S.S. 304, S.S. 316 or bronze. Mountion flanges are of C.S.,S.S. Or bronze. Switch housing is of cast aluminuium or stainless steel flame - proof / weather-proof.

Appilication include low/high level alarm, pump control, motorised valve control, diaphragm or piston, control valve operation.
These switches are normally mounted into the sides of tanks or pressure vessels. These level swiitches are of low differential and are normaliy used for singlie level control. They can be mounted externally through isolating valves for application like Boilers, Reaction-Kettles etc. Which can be isolated for regular servicing

Operation: The float assembly carries a permanent magnet which is opposed by asimilar magnet in switch assembly. The adjacent
poles of magnet repell each other through the wall of the switch housing. This principle gives snap action of the switch contacts.
The standard level switch can be modified for providing adjustable differentials by extended float modification. The extension.rod can be increased in lenght to 0.5 mtrs for differential of upto 300mm.
Submerged models of level switches are recommended in case level switch cannot be fitted to side or top of the tank or for underground tanks.

External Cage Vertical Level Switch

This is one of the most widely specified controls. This is designed for control of specific gravity' 0.4 above. This level switch in its various models (MB100, 200, 300. 400) is used at working pressure ranging from vacuum to 3000 psi. This switch is externally mounted and can be piped anywhere near the tank or a distance from it. They are easy to install. High and low levels are indicated on the outside of the switch. Fine adjustments can be made by moving the switch assembly up or down on the enciosing tube. assuring exact liquid level control.

Several units can also be ganged for multi-level control. Cooling fins can be provided for higher temperatures. Explosion-proof housing is provided for the switch.

Operation: The float in the chamber responds to the changing liquid level, raising or lowering the magnetic piston inside the enclosing tube.Magnetic proximity switch or mercury switch is fastened tothe external of enclosing switch and can be adjusted and locked at the desired actuating level. Then (depending upon the application) the magnetic piston attracts or releases the switch.

Applications: This switch is designed for external installation on receivers, scrubbers, storage vessels and for alarms, solenoid valves. pumps, and pneumatic devices and all low specific gravity (min. 0.4) applications.

Top Mounted Level Switch

Model MC 100 : Top Mounted Single Level Control Switch	Model MC 120 : Top Mounted Multi Level Control Switch
This model is designed for vertical mounting at the top of the vessel. Connection is through screwed or flanged ends. And is suitable for liquids with specific gravity of 0.5 to 1.4. The switch is operated by magnetic piston which actuates the magnetic proximity switch. This switch is normally used for single level control and suitable for high immersion depths upto one mtr.	Thsi level control switch puts the high and low level limit control in one compact connection. This level control switch employs two switches and two float mechanisms to indicate high and low level and the thereby allowing separate switch action. the tandem float assemblies are provided for independent switch actuation
Model MC 200 : Top Mounted Centre Guided Reed Control Switch	Model MC 300 : Top Mounted Free Gravity Displacer Type
The float is guided by central tube. The float camies a magnet which moves up and down the central guide and accuates a reed switch provided at intervals enclosed in the central tube. The float diameter is approx. 62 mm. The central guide tube diameter is 20 mm.	This top mounted level switch is operated by S. S. or porcelain displacers which are suspended by a wire rope at different intervals. The rising liquid on reaching the displacer creates an upward buoyancy force which relases spring loaded magnetic piston in the enclosing tube. This actuates one or more proximity switches. This is ideal for underground tanks with very high depths. One or more switch assemblies can be provided for single or multi level control.
