The Curtiss-Wright SLS190 series of potentiometers

Curtiss-Wright Corporation makes many innovative measurement solutions available in Canada through Durham Instruments, such as the SLS190 series of linear potentiometers. This is a new and revolutionary range of linear position sensors designed to offer maximum performance benefits within a highly compact size, with stroke lengths from 25 to 350 millimetres (mm).

Each of these unique devices is available from the distributor with a convenient selection of mounting options and accessories.

Many unique design features

These linear potentiometers come with the proven advantages of Hybrid Track Technology and many unique design features. The SLS190 series also has a high wiper contact resistance, so users should carry out operational checks only in the voltage divider mode. Users should employ Hybrid Track potentiometers only as voltage dividers, with a wiper circuit impedance higher than 100 x track resistance, or ½ a mega-ohm, whichever is larger. With lower impedance in the wiper circuits, operation will degrade the output smoothness and affect the linearity.

Key features of this series include a short body to stroke length, compliance with the CE safety standard, corrosion-resistant rod end bearings, integrally moulded cable assembly, and light weight. Options available:

  • Compact shaft – reducing dimension B by 25 mm
  • Extended cable length – a ten-metre output cable can be specified
  • Integral shaft seal – compliant with the IP66 rating
  • Mounting – body clamp or flange mounting kits can be supplied
  • Protective sleeve – for all stroke lengths. Self-aligning bearings only

Other characteristics: virtually infinite resolution, dither life at 200 million operations at plus or minus ½ a mm and 60 hertz, and replaceable shaft seals that last for 20 million operations.

These linear potentiometers are recommended for a wide variety of general-purpose applications, like medium-stroke linear position sensing – especially in the high-volume manufacture of original equipment, in which top performance and reliability with competitive pricing and fast dispatch are of major importance. Durham Instruments deems them suitable for use in aerospace, automation, food processing, forestry, education, the medical sector, the military, mining, packaging, power generation, alternative energy, transportation, and research and development.
