The SP3 from Celesco is a compact, economical stringpot
that provides a user selectable 4-20 mA or 0-10 Vdc output
signal. Simply install this sensor using the handy mounting
bracket and connect the appropriate wires for the desired
ouput.
The SP3 is constructed with a rugged, water resistant poly-
carbonate body that has been compactly designed for tight
spaces and generous measuring cable misalignment. With
4 dierent ranges, the SP3 is a perfect solution for many ap-
plications from light industrial to OEM. Just like all of our
other SP and SE models, the SP3 is in stock ready to ship.
