A strange phenomenon with the flap-type level transmitter
Thread Content
Dear experts, I’ve noticed a strange phenomenon at my workplace: the level gauge of a tower reactor has a range of 1700 MM. The output values at the zero and full positions are normal, at 4 mA and 20 mA respectively, but the output at the intermediate position is 13.4 mA higher than expected. What could be causing this? I’m unable to resolve it
This is probably caused by the poor linearity of the resistance of the magnetic flip switch
The linearity isn’t good; it seems there’s no other solution except to replace it.
The accuracy of magnetic flap valves is just laughable
