Multi-Level Switch Small Size from Almeg Controls

Small Size multi level controls are similar to the larger level control model in so much as doing the same job - only this model uses smaller floats and probe allowing for tight or constricted 

applications. Choose from one to four stations in most material and configurations.

         

1) Choose the process connection and then move across to the required float.
     eg. SSR20 - 1 = 2" NPT with SS float

2)Determine switch points  ( from 1 to 4) and then the level or switch point measured form below the thread and the state.

The state means normally open (N/O) or normally closed N/C in the dry position - no fluid in the tank. 

N/O is indicated with a letter "A"  switch closes on rise opens on fall

N/C is indicated with a letter "B" switch open on rise closes on fall

3) Choose unit of measure "C" indicates inches    "D" indicates millimetres

Example

SBR20 - 1 -10A - 15A - 20B - 25A - C = SS probe, 2" NPT, L1 = 10" N/O, L2 = 15"N/O, L3 = 20" N/C,
            L4 = 25" N/O

or

SBR50 - 4 - 6A - 18A - 36B - D = 

Brass probe,  1/2" NPT facing up, 1" interface floats, L1 = 6mm N/O,  L2 = 18mm N/O ,  L3 = 36MM N/C

NOTE

• Minimum distance between switch points using one float  making bottom N/C top N/O is 1/8" +/-

• Minimum distance between switch points using a float for each station is 1 3/4"  

• 1" of probe is required after the last level or point
