Macro Sensors (Pennsauken, NJ) has announced that the HSIR Series LVDT Linear Position Transmitters are serving as level sensors to measure liquid level changes from a few inches to several feet in gauging tank level volumes. In this LVDT level sensor configuration, a stainless-steel float coupled to a nonmagnetic stainless-steel rod is attached to the high-permeability, armature core of the LVDT.  Features include:

  • Ranges of 1.00 to 10.00" (25 to 250 mm).
  • 4 to 20 mA input/output.
  • Non-linearity of ±0.25% of FRO or better.
