A diaphragm level switch is mainly used to measure the change within pressure caused by the level of the material increasing or decreasing. Whenever the level increases, then air pressure gets high & the diaphragm face drops under the force, which actuates a micro switch. Once the force gets lower, the diaphragm comes back to its early position.

To install the level switch consider the following points for correct level measurement: Keep the sensor at least 50 mm (2″) away from any nozzle or tank wall. If multiple units are used, allow at least 100 mm (4″) between them, to prevent interference (mount diagonally if space is restricted). High level alarm Normally mounted into the vessel top

Because of this, they are normally used for narrow level differential applications such as high level alarm or low level alarm. Magnetrol float level controls use a simple float and magnetic coupling action. As the float rises or falls with liquid level, it moves a magnetic sleeve into or out of the field of a switch actuating magnet, causing

zdas04 (Mechanical) 25 Nov 14 11:29. "High high" is physically higher in the vessel than the "high" alarm. The only reason for two set points is that they do different stuff. Most often in my experience, the high level gives you an alarm, but no process changes. The high-high is often connected to a shutdown or some other major process change.

Point level sensors or multi-point sensors mark a specific level and communicate to the user if the media is above or below that level. They are used generally as a high alarm or switch. These level sensors can also be integrated in a single device to add a low alarm, or to serve as a stepped version of a continuous level.
