Accurately Measure Linear Displacement TE Connectivity's (TE) Linear Variable Differential (LVDT) and Linear Variable Inductive Transducers (LVIT) absolute position transducers make accurate measurements with excellent resolution and repeatability. Offered with various packaging options, LVDTs and LVITs offer an extremely long life expectancy in harsh environments and critical applications. These sensors feature friction-free, non-contact inductive magnetic coupling for extremely long cycle life and virtually infinite resolution. Various off the shelf and custom packaging options are available for the most demanding application requirements.
AC operated Schaevitz, Macro Sensors, and TE Connectivity Linear Variable Differential Transformers (LVDTs) contain no electronics making them an excellent choice for applications with size restrictions or harsh operating environments. DC 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 voltage, current or digital outputs. LVDTs with a spring-loaded plunger and bearing assembly (gageheads) allow for easy installation; AC, DC and digital output versions are available in ranges from +/-0.020” to +/-2.000”. Separate core LVDT's are available in configurations including: miniature (AC), general purpose (AC, DC and loop powered), sealed (DC, loop powered), hermetically sealed (AC, DC), submersible (loop powered), hazardous locations (AC) and custom separate core LVDT's.
