USPR-2-Metal Case

Download Add Inquiry
The HC SP/USP series is designed with a rugged steel casing, which has good resistance to electromagnetic interference and high electrical overload capacity. It is a stable and reliable measurement unit, suitable for field operations and laboratories.

The USPR-2 Resistance transducer has Dual analog output.The USPR offers 50 ~ 20k ohm range seletable.

*The SP series is a traditional analog product, and the USP series is a new digital product. SP series products are partly replaced by USP series, the input and output terminals and functions are the same, and can be directly replaced.
