Overview of ILPS-27 Series LVIT Linear Position Sensor

An overview of the ILPS-27 series LVIT Linear Position Sensor


The ILPS-27 series of linear position sensors from Harold G. Schaevitz Industries 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 output signal that is proportional to the change in stroke.

ILPS-27 LVITs are versatile devices that are used in a wide range of commercial and industrial applications, including automotive testing, automated assembly systems, and packaging equipment.

The ILPS-27 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 1 inch O.D. aluminum or stainless steel, and rated to IP-67.

ILPS-27 LVITs include swivel rod ends for ease of mounting, and a choice of an M12 connector or Integral Cable connectivity.

ILPS-27 LVITs are rugged, dependable, and have an excellent stroke-to-length ratio, making them an ideal solution for your demanding application.
