Problem of frequent drift in radio frequency admittance
Thread Content
Our radio frequency admittance keeps having problems; it works fine today, but tomorrow it either stays at the minimum value or crashes at the maximum value. Help! ! !
I have mentioned before that radio frequency admittance measurement, based on the principle of capacitance values, is prone to significant errors. Especially unsuitable for media with changing components!

Reply to 4# Galaxy One: Is there any solution? ? ?
Water has entered the electrodes; the electrodes are too dirty, or there is water at the joints of the connecting rods. If the liquid level gauge from Siemens is used with a dirty measuring medium, maintenance becomes very troublesome
The dielectric constant changes so much; it’s no wonder there is drift. Is it a liquid or a solid?
