LEVEL SWITCHES & PANNELS
MODEL MA 100 / MA 200 SIDE MOUNTED LEVEL SWITCH
MAGTROL Level switches are suitable for filling into tanks and pressure vessels for indicating and or controlling the level under atmospheric, vacuum and pressure conditions. Magnetic switches are snap action and glandless and eliminates any chance of leakage. These are suitable for temperatures upto 400 degrees centigrade and pressure upto 40 kg per cm2 Switch is magnetically operated and is of micro, Mercury or air valve type. Material of construction is of S.S. 304, S.S. 316 or bronze. Switch housing is of cast aluminum or stainless steel flame proof / whether-proof.
Application include low / high level alarm, pump control motorized valve control; , diaphragm or piston, control valve operation.
These switches are normally mounted into the sides of tanks or pressure vessels. These level switches are of low differential and are normally used for single level control. They can be mounted externally through isolating valves for application like Boilers, Reaction - Kettles etc. Which can be isolated for re gular servicing.
The float assembly carries a permanent magnet which is opposed by a similar 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 modifying for providing adjustable differentials by extended float modification. The extension rod can be increased in length to 0.5 mtrs for differential upto 300 mm.
Submerged models of level switches are recommended in case level switch cannot be fitted to side or top of the tank or for undergrounds tanks.
MODEL MA 300: SIDE MOUNTED EXTERNAL CAGE LEVEL SWITCH
This switch is externally mounted by providing two isolating valves and the level switch can be attended to even when the tank is under pressure. This switch is ideal for installation on boilers and chambers are constructed as per Indian boiler regulation.
MODEL MA 400 SIDE MOUNTED LOW PRESSURE LEVEL SWITCH
This is a simple model wherein the reed switch is operated directly by a magnet installed in float
assembly Single N.O contacts are available. This switch is available S.S, P.P, PVC, HDPE, etc.
MODEL MB 100 EXTERNAL CAG 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 use d at working pressure ranging from vacuum to 3000psi. 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 enclosing tube assuring exact liquid level control.
Several units can also be ganged for multilevel control. Cooing fins can be provided for higher temperatures. Explosion-prof housing is provided for the switch.
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 to the external of enclosing switch can be adjusted and locked at the desired actuating level. Then (depending upon the application) the magnetic piston attracts or release the switch.
MODEL MB 400 :
This model is similar to the above models except that it is used for higher differential providing two switch assemblies on the enclosing tube operated by a single float or two switch assemblies installed on the enclosing tube operated by double tandem mounted float. A single switch can be used for both high level with large differential.
|TOP MOUNTED LEVEL CONTROLLERS
|Model MC 100: TOP MOUNTED
SINGLE 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.
|MODEL MC 120 : TOP MOUNTED MULTI LEVEL CONTROL SWITCH
This 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 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:
The float is guided by center tube. The float carries guide and actuates a reed switch provide d at intervals enclosed in the central tube. The float diameter is approx... 62 mm. The central guide tube diameter is 20 mm.
|MODEL MC 300 : TOP MOUNTED FREE GRAVITY DISPLACER TYPE
This top mounted level switch is operated by S.S. or porcelain displacers which are suspended by a wire rope. The displacers can be mounted on the w ire rope The displacers can be mounted on the wire rope at different intervals. The rising liquid on reaching the displacer creates an upward buoyancy force, which releases 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
