I have 2 tanks , one is under another and hopes to pump from under tank to upper one using a 0.5 Hp single phase motor.By connecting float switches for both tank,can I control the motor to turn on when the water level of lower tank is high and switches off when the water level of upper tank is high ( Upper tank has lower capacity than Lower ) and vise versa
According to the datasheet the sensor and under the assumption that it works like https://www.youtube.com/watch?v=tA76sm_jJTk it can be used directly without the need of any additional circuit:
The parts are taken from the datasheet chart 2 and 5.
Yes, by using a relay, wired up as a latch. You have the high-limit switch as SPDT type which can serve as a cut-off.
Here's how it works:
- The lower tank-high switch energizes the coil.
- Relay self-energizes through one set of contacts, which latches it.
- The upper tank-high switch turns off the relay, latch opens.
The connection looks like this:
