IEPE accelerometers

SM103 and SM102 side exit integral cable accelerometers

SM Series of Integral Cable Sensors

Model: SM102 and SM103

The SM Series of integral-cable, side-mount sensors are a budget friendly line of accelerometers designed for ease of installation, even in hard-to-reach spaces. The pivoting mounting base allows sensor installation in any orientation - the user can turn the sensor 360° and tighten the base when the ideal mounting orientation is achieved for minimal cable strain. It can be used for condition monitoring of rotating equipment in tight-clearance installations, aggressive environments, or submerged locations.

Key features and benefits

  • More affordable than other side-exit, integral-cable sensors – without loss of reliability and performance
  • Compact size with low profile to fit in tight and hard-to-reach spaces with low clearance requirements
  • Pivots on integral mounting base for 360° cable orientation with reduced cable strain
  • Mountable in various orientations and locations, allows users to tighten sensor in final measurement position
  • Integral cable for submerged or aggressive environments

Mounting 1/4-28 stud

SM Series accelerometers pivot on an integral mounting base. This makes it possible to easily position the sensor and connector with minimal strain on the integral cable. To install, simply thread the sensor's hex nut onto the mounting stud. Rotate the sensor to position the integral cable to the desired location and tighten the hex nut.
