| MAGNETIC LEVEL SWITCH - SIDE MOUNTED |
|
|
|
|
| |
Magnetic level Switch(side mounted type) is float operated working on magnetic repulsion principle. Simple in design |
|
| |
and robust in construction together with strict quality control makes the switch a very reliable product. |
|
| |
This can be used for initiating high or low audio-visual signals or automatic level control of liquids in pressurised or open |
|
| |
tanks, containers, hot water service, sterilizing equipment and a variety of process control fluid tanks. |
|
| |
|
|
|
|
|
| |
|
|
| |
|
|
| |
The float assembly carries a permanent magnet. With the float movement this magnet repels another magnet kept inside |
|
| |
the switch housing which inturnactuates a micro-switch having snap action of contacts. |

| MAGNETIC LEVEL SWITCH - TOP MOUNTED |
|
|
|
|
| |
Level Switch (top mounted type) facilitates any number of pre-determined level controls initiating audio-visual signals |
|
| |
with a single unit. It is designed to provide reliable operation in severe industrial applications. The unit consists of a vertical guide |
|
| |
pipe (stem) within which are located the sensor switches, magnetic float sliding over the stem according to the level in the tank, |
|
| |
switch terminal housing(head) and necessary mounting connection. |
|
| |
The Switch operates on the basis of the float principle with magnetic transmission (permanent magnet-reed switch). |
|
| |
The switch is encapsulated in the stem and it is actuated by a permanent magnet with in the float. |

| MAGNETIC LEVEL SWITCH- TOP MOUNTED |
|
|
|
|
| |
Because the switches operate on the principle of magnetic-flux coupling with no mechnical connections, fluid contamination of |
|
| |
switch components cannot occur. |
|
| |
Only one moving component exists-the no wear float. |
|
| |
Reliable in operation because of the large gap between the slide tube of the float and the fixed guide tube. |
|
| |
Insensitive to dirt particles in the liquid. |
|
| |
Several levels can be monitored by several reed contacts in the guide tube even with one float. |
|
| |
Suitable for any fluid compatible with material of construction and sp. Gravity above O.7. These Switches operate in any position |
|
| |
-from vertical to an inclined angle of 45°,head assembly upward or downward. |
|
| |
Closing,opening or change-over contacts can be selected. |
|
| |
Factory-set level actuation points can be easily adjusted at site. Minimum possible actuating distance from top of connection is |
|
| |
30 mm. |
|
| |
Minimum possible distance between 2 level set points is 75 mm, if 2 independent floats are used. |
|
| |
All the floats and stoppers can be removed thro' bottom side of stem, if necessary. for easy installation in your vessel and retain |
|
| |
them to their original positions. |
