New low-cost string pot sensor features user selectable current or voltage output
General purpose cable extension sensor has flexible built-in options in a compact durable housing
Variohm EuroSensor's new SP3 String Pot sensor from Celesco Inc. features a rugged cable extension design with a plastic-hybrid precision potentiometer and winding drum in an economical and flexible package that can be user configured for a choice of 4-20 mA or 0-10 VDC output by simply connecting the appropriate signal wires on installation.
With precision absolute linear position measurement in a choice of four ranges covering 120 mm, 315 mm, 635 mm and 1270 mm, the extremely compact unit can be mounted within an envelope of just 25 mm wide x 50 mm deep x 90 mm high and its durable water resistant polycarbonate housing has four point fixing and a bracket that facilitates universal mounting. The cable extension sensor requires no critical cable alignment which suits difficult to measure applications where there is no space to fit more traditional measurement devices or where the moving components may be submerged or obscured by other equipment.
The SP3 has an acceleration rating of up to 15g in retraction and a rated life of over 2.5 million cycles for the 120 mm travel unit (250K cycles for the 1270 mm travel version). Overall accuracy is between 0.25% to 1.0% FS depending upon stroke length, repeatability better than 0.05% FS, and the measuring resolution is essentially infinite.
The supply voltage is 8 - 40 VDC for the current output version and 12 - 32 VDC for the voltage version. Electrical connection is via a 1 metre multi conductor cable.
With competitive pricing and stock availability from Variohm, the SP3 offers high reliability and ample levels of precision for many applications in light industrial machinery and OEM equipment.
