Top Connection Sensors | Low Profile Sensors | Integral Cable | Specialty Sensors | Triaxial Sensors

Low profile accelerometers & piezovelocity sensors offer many advantages over top-connector style accelerometers; the lower profile effectively eliminates the

connector / cable dimension from the combined height of the mounting magnet, sensor and connector / cable assembly used for periodic analysis. Measurements

can now be performed more easily in tight places such as between drive and driven equipment. In permanently mounted applications, the low profile sensor

offers more mounting flexibility while allowing the installer to position the cable exit from the sensor in the most desirable direction.
