SPD Series
Description:
This compact stringpot provides the ultimate in ease-of-use and exibility. This sensor
ts in small spaces, doesn’t need perfect alignment, mounts in just about any direction
imaginable and has a unique circuit that lets the user choose 4-20mA or 0-10Vdc output
on the y. The SPD comes in 2 different stroke ranges up to 50 inches and is
constructed with a rugged polycarbonate body sealed against IP67 (wet) environments
for both indoor and outdoor applications. Every unit ships with a stainless steel mounting
bracket that lets the user easily point the measuring cable in the direction needed.
High value and economical price makes this sensor the perfect choice for the OEM
and single-piece user alike. Customer specic designs available for the OEM, please
contact factory for more information.
