Overview of Heavy Duty Linear Sensor LV-45 Series

The LV-45 series of linear position sensors from Alliance Sensors Group, a division of H. G. Schaevitz LLC, offers reliable long-life operation utilizing LVIT linear variable inductance technology.

LVIT technology consists of a high resolution inductive sensing coil element coupled to built-in smart electronics. A conductive tube referred to as a Spoiler travels over the coil element changing the inductance.  The smart electronics then generate an analog or digital output signal that is proportional to the change in stroke.

LV-45 LVITs are robust devices that can withstand high vibration and shock commonly found in mills and power plants, as well as the temperature and humidity extremes found in outdoor bridge and structural testing applications.

The LV-45 is available in measuring ranges up to 18 inches with choices of analog voltage, current, or digital output signals.  Analog output signals are adjustable using the SenSet field calibration feature.

The housing is constructed of heavy wall 1 and 3/4 inch O.D. stainless steel and rated to IP-67.

LV-45 LVITs include swivel rod ends for ease of mounting, and a choice of M12, Mini-fast, or Integral Cable connectivity.

LV-45 LVITs are extremely rugged making them ideal for demanding applications where many other position sensors cannot survive.
