SchaevitzR is the most trusted name in LVDTs (linear variable differential transformers). Measurement Specialties offers a broad range of standard SchaevitzR LVDTs as well as specialized products for extreme conditions of heat, pressure, radiation and weather. The SchaevitzR LVIT-Z (linear variable inductive transducer) offers our proprietary linear displacement technology and signal-conditioned circuitry on a single printed circuit board for low cost/high volume OEM applications. In the SchaevitzR LCIT (low cost inductive transducer), the conventional ferromagnetic core has been replaced with a low-cost conductive spoiler and cost-effective coil design for increased frequency response without increased signal noise, making the LCIT ideal for highly dynamic applications. Complementary products include LVDT transmitter systems and gageheads. Applications for linear position transducers include industrial process control, valve position, roller gap control, instrumentation, aerospace and automotive.
AC operated Linear Variable Differential Transformers (LVDT’s) contain no electronics and are therefore the first choice when small size, hostile environments or low cost are required. AC LVDT’s when used in conjunction with Schaevitz Signal conditioners (see Instrumentation) offer the maximum amount of flexibility for outputs and scaling. Ranges from +/-0.005” to +/-10.000” are available.
LVDTs with a spring loaded plunger and bearing assembly (gageheads) allow for easy installation. The core rod assembly does not need to be attached to the part to be measured making the gagehead an ideal solution for assembly lines and gaging stations. AC, DC and digital output versions are available. Ranges from +/-0.020” to +/-2.000” are available.
DC operated Linear Variable Differential Transformers (LVDTs) have signal conditioning electronics built into the LVDT and require no calibration or special signal conditioning. Units can be powered with uni or bi-polar DC voltages and have scaled DC voltage, current or digital outputs. Ranges from +/-0.050” to +/-10.000” are available.
LVDT transmitter systems are two wire looped powered sensors ideal for applications in power plants and industrial environments with long cable runs. Units are available with zero and span adjustments and intrinsic safety approval. Ranges from 0.25” to 10.000” are available.
