How to calibrate level switch?..

Suppose you using Float/ displacer type of level switch.
Do the followings:
1. Fill the process into chamber of level switching mark.
2. Contacts of level switch should be changed.
3. If already, closed contacts, then should change to open condition.
4. If contacts not changing, do the knob of switch to change.

Suppose you can not fill process into chamber.(Process may harmful, like ammonia etc).
1. Note the process specific gravity. Suppose it is 0.67.
2. Your height for level switching is 1000 mm.
3. Use water to fill into chamber for calibration instead of process.
4. 1000 x 0.67 = 670 mm
5. So fill into chamber up to 670 mm water. It will operate the switch.

Answer / mahalingam

The switches all are working in Digital mode.Like 0 or 1. To do the calibration confirm the NO & NC. Basically it is NC when the process reaches the desired level then the circuit will be NO.
