Is a magnetic float remote level gauge powered separately by 24V? Is there a current signal in the circuit?
Thread Content
I am working on a level measurement device, providing 24V power separately to the magnetic float remote level gauge. When the liquid level changes, will there be an electrical signal in the circuit?
There is a current signal; when the liquid level changes, the circuit current changes linearly.
Does it mean four-wire system? I’m a bit confused by your current approach
Yes, remote level gauges are generally 24VDC two-wire systems
The current must change...
Yes, there are on-site indicators as well as remote indication options; the signal is in the form of current. The manufacturer’s phone number is usually provided on them, so it’s best to get in touch with them for more details.
Of course there will be, with 4-20MA changes
