- This level switch for “side” use is very versatile: like the “RL” range, it can also be used to control the maximum or minimum level and for controlling the minimum plus empty or maximum or overflow.
- Unlike the “RL” range, the distance between the 1st and 2nd signal is not fixed, but has an angular value, which gradually increases with the length of the rod.
- This gives the designer many choices; in fact, by varying the length “L”, the switching points of the 1st and 2st Reed vary (read on axis 1 and 2).
- The Level (see diagram S3) can likewise be used to start a pump (1st Reed) on axis 1; the contact will remain closed until axis 2.
On axis 3 there will be the alarm signal (with diagram S4 there will also be the O.K. signal).
