| Level Controllers |
|
|
|
Level Controllers in general
• Conduktive measurement (assumes substrate will carry electric charge;
i.e. non-resistive / inert substrates)
• Variable sensitivity ranging
• Probes are operated with alternate current signal
• System supply and measurement cirquits are galvanically separated
• Safety cirquit: filling or emptying operation is cut-off in case of power failure
or transformator damage
|
|
Level Controller S-NR 01 / S-RN 01
Sensing for 1 or 2 levels
 |
|
|
• Test-button for the functional test of the
measure and alarm cirquit
• LED indicators for relay state and operation
• Probes are operated with alternate current
signal (even with 24V DC supply)
|

|
|
Level Controller NR 98 / RN 98
Sensing for 1 or 2 levels
 |
|
|
• LED indicators for relay state and operation
|
| |
|
|
|
Dual Level Controller D-NR 98 / D-RN 98
Sensing for 2, 3 or 4 levels
 |
|
|
• Any 2 functions can be combined as to
customer needs
• LED indicators for relay state and operation
|

|
Dual Level Controller D-NR / RN 98
Sensing for 2, 3 or 4 levels
 |
|
|
• Any 2 functions can be combined as to
customer needs
• LED indicators for relay state and operation
|
| |
|
|
|
Level Guard ULW
Sensing for 1 level
 |
 |
|
• Basic function: issue an alarm notification
e.g. for leakages or overfilling
• LED indicators for: Alarm - Ready - Stop
• Probe cable supervision:
in the case of damage or interruption in the
probe cable, the "Stop" state will be entered.

Level Controller NR / RN 01
Sensing for 1 or 2 levels
 |
|
|
• The NR / RN mode can be selected by jumpers
• LED indicators for relay state and operation
|
| |
|
|
|
Level Controller NR / RN 02
Sensing for 1 or 2 levels
|
|
|
• 2 separate change over output contacts
• The NR / RN mode can be selected by jumpers
• 3 coarse levels of sensitivity can be selected
by jumpers
• LED indicators for relay state and operation
|
| |
|
|
|
Level Controller NA-EV
Sensing for 1 level
 |
 |
|
• Suitable to keep a constant level:
e.g. in swimming pools and ponds
• delay timer
• probe cable supervision
• Probes are operated with alternate current
signal
• LED indicators for the operation state:
ON - FILLING - STOP
• Test-button for the functional test of the
measure and alarm cirquit
|

|
Level Controller NR 98LS, RN 98LS
Sensing for 1 or 2 levels
 |
|
|
• Open frame for mounting in fuse / controll box
• LED indicators for relay state and operation
