The 1-channel level control MS91-12-R monitors and regulates conductive liquid levels

(II). As a dual level regulator, it can be used

to control pumps and solenoid valves (I). As

monitoring device it is designed for run-dry or

over flow protection.

The sensitivity (liquid resistance) is adjustable

between 0.1 … 100 kò. One of the four sensitivity ranges is selected by the terminal configuration. Fine adjustment of the switch point

within the selected range is achieved with a

front cover potentiometer. The level controller

not only provides optimum reliability in differentiating liquids, it is also suited for the distinction between foam and liquid .

The adjustable switch-on and switch-off delay

is very important for turbulent liquid levels. A

delay time between 0.1 … 15 s can be set via

the potentiometer on the front.

Two parallely operating relay outputs with one

changover contact each are provided to output the switching commands. The output configuration of both outputs can be changed

from NC mode (no bridge between terminal

15/16) to NO mode (with bridge between terminals 15/16).

The switching status is indicated by a yellow

LED.

The switching status of the output is indicated

by a yellow LED and operational readiness by

a green LED.
