is 3 level sensors worth the money

[larryfl1]

hey all...

i dont have a ex so i can only have 2 sensors...

i was planning on starting pump when low is triggered and stop when high sensor is triggered...

is it worth the extra $ for the ex upgrade so i can have a 3rd level sensor? i was thinking of the ex and microwave sensor for high stop..but hate to spend the money if its not worth it...

thoughts???

You can go that way, or you can get the expansion card as detailed in the quote from Matthias below)
4 extra digital inputs on this card.
If you have the need of the extra expandability of the EX, Conductivity etc, then that may be a better route to take??
As you say, work out the $ for your needs!

2 analog inputs 0-10V
4 digital inputs
all optically isolated
