MLP APPLICATIONS

1) This installation is typical for most high level sensing applications where the vessel is accessible from the top. If high temperature is expected within the vessel then have a close look at diagram number 2. An extension tube can be fitted which has some ventilation holes in the side, however there are some other considerations. Firstly, there should be a suction system already installed onto the vessel which would cause a vacuum draft through the holes in the extension tube to keep the heat away from the bearings. Secondly, the internal vessel temperature may melt the nylon rod if it exceeds 110oC. You may need to fit an alternative probe rod, such as Teflon or metal etc. (Call us for advice)

2) This installation is typical for most high temperature applications where the probe is mounted in the side or top of the vessel. An extension tube can be fitted which has some ventilation holes in the side, however there are some other considerations. Firstly, there should be a suction system already installed onto the vessel which would cause a vacuum draft through the holes in the extension tube to keep the heat away from the bearings.

3) This installation is typical for most low level sensing 4 applications where the probe is mounted in the side or top of the vessel The reason for the angle of the mounting facility is to reduce the amount of abrasive buildup around the drive shaft and seal area. The probe should protrude into the vessel about 200 to 300mm in this type of application.

4) This installation is typical for most high level sensing applications where aggregate is the product being sensed. The rod usually hangs from up to 3.5 meters above the aggregate bin and will not have any problem stalling the motor under these conditions. For low level sensing applications we use a short flat nylon sensing tongue and mount the unit as per diagram 3 above because of the downward forces of the material being applied to the rod. (Consult the factory for more details on the flat nylon tongue)
