Of course, you really need two. One to trun the pump off when the
level falls below the setting, the other to turn the pump on whe the
level rises.

Now comes the tricky part. It needs some form of memory to realize
that it has turned on because the water level rose, but it shouldn't
run off until it clears the lower sensor. This could be a simple
relay, but now we are adding complexity and more failure modes.

So perhaps there is a simpler method, for example using fluid logic,
that might be more reliable?

Maybe there is. Only needs one switch. This concept is for a sump pump
mounted in the basement.

Make sure the pump has an anti-siphon valve at the exit. Most do - it is
silly to try to pump water out of the basement and have it return as soon
as the pump stops.

Connect the tube for the diaphram switch at the pump housing near the
exit and anti-siphon valve.

Adjust the diaphram switch to turn on at the desired water level.

When the pump turns on, the water pressure will keep the switch closed.

When the pump runs out of water, the anti-siphon valve will prevent water
from flowing back into the pump. The pressure will drop, opening the
diaphram switch. The pump turns off and the system waits for the next
cycle.

Of course, there may be some additional details that require solution, or
the OP may have a completely different need in mind.

But this eliminates the adjustment problems and unreliability of the float
and level switch.

This is the kind of float switch I was thinking about. They are pretty
reliable, since they have no external adjustments or moving parts:

The only disadvantage these have is in an environment where they might
get tangled up with something.

I've had different problems with sump pumps all my life. Rarely the same
thing twice. Anything with wires, rods, levers, floats, plugs that come
loose, corroded switches, and so forth. I'd minimize the number of moving
parts and keep them protected inside the housing so nothing can get at
them.

Hi,
I have seen a scope which has

1 Mohm 30 pF input impedance

and frequency response

0 to 12MHz (+/- 3dB)

My question:

What is the difference between input impedance
and frequency response?

input impedance has to be driven, and so will prsent power transfer to
the voltage mesurement equipment, and the 3db response of the line by
wobble matching the graticule scale, will be the bandwidth. the line
driver has its own input impedance, which can only be driven by limited
power.

ok?

Huh? (in response to what Jacko wrote)

x-posted to s.e.b where this is more appropriate.

The input impedance of the measurement device specifies the load it
presents to the signal being measured. It is important to know for a
number of reasons.

The +/-3dB response is specified as that is how bandwidth is normally
specified (-3dB is a half power point). In this case, it specifies that
the amplitude response of the scope is within 3dB between DC and 12MHz.

I would suggest a google search for some basics (although s.e.b. can be
an appropriate forum too).

Cheers
