Industrialeveline™ Liquid Level Controls & Probe Holders

Load Circuit Can Be Either Opened Or Closed When Liquid Touches Probe

SEQUENCE : With magnetic motor starter, depress start button, load goes on.  When liquid reaches probe, load goes off.  For emptying operation,  load goes off when liquid falls below probe.

High-Level Alarm And Signal Light Operation

SEQUENCE : When liquid touches the probe, alarm and light go on.  Depress alarm stop button, alarm goes off, but light remains on.  When liquid falls below the probe, light goes off.

Low-Level Alarm And Signal Light Operation

SEQUENCE : When liquid falls below the probe,  alarm and light go on.  Depress alarm stop button, alarm goes off, but light remains on.  When liquid touches the probe, light goes off.

Automatic Filling

SEQUENCE : When liquid falls below low level probe,  load goes on.  When liquid reaches high level probe, load goes off.

Automatic Emptying

SEQUENCE : When liquid reaches the high level probe,  load goes on.  When liquid falls below the low level probe,  load goes off.

Alarm And Signal Light Operation.

SEQUENCE : When liquid reaches the high level probe,  alarm and light go on.  When liquid falls below the low level probe,  alarm goes on,  but light remains off.  When liquid is between the high and low level probes,  both signals are off.

Two Isolated Normally Open Circuits,  One Circuit Closed At Each Level

SEQUENCE : When liquid reaches the low level probe,  load 1 goes on.  When liquid reaches the high level probe,  load 2 goes on.

Automatic Filling With High Level Signal

SEQUENCE : When liquid falls below the low level probe,  load goes on.  When liquid reaches the middle level probe,  the load goes off.  If liquid reaches the high level probe,  the signal goes on.

Automatic Emptying With High Level Signal

SEQUENCE : When liquid reaches the middle level probe the load goes on.  When liquid falls below the low level probe,  the load goes off.  If liquid reaches the high level probe,  the signal goes on.

Automatic Filling With Low Level Signal

SEQUENCE : When liquid falls below the middle level probe,  the load goes on.  When liquid reaches the high level probe,  the load goes off.  If liquid falls below the low level probe,  the signal goes on.

Automatic Emptying With Low Level Signal

SEQUENCE : When liquid reaches high level probe,  the load goes on.  When liquid falls below the middle level probe,  the load goes off.  If liquid falls below the low level probe,  the signal goes on.

Three Isolated SPDT (form C) Relays

SEQUENCE : Each relay operates off its corresponding probe.  Liquid reaches low probe,  load 1 goes on,  load 2 goes off.  Liquid reaches middle level probe,  load 3 goes on,  load 4 goes off.  Liquid reaches high level probe,  load 5 goes on,  load 6 goes off.

4 Level Operation

SEQUENCE : Alarm#1 goes on at high level probe.  Alarm#2 goes on when liquid falls below low level probe.  Load goes on and off between 2 immediate probes.  Frequently specified by water / waste pumping stations.
