Linear and Rotary
Variable Differential Transformer (L/RVDT)

The choice for applications where the physical environment is most difficult, including extreme pressure, extreme high or low temperature, and extreme shock and vibration. Also often used for very long term reliability requirements. Signal conditioning electronics are generally located separately from the sensor in a more benign environment. Variety of analog outputs.

Contact / Contactless Operation; Moving Element Material Characteristic	Contactless Moving Element is high permeability metal
Linear Measuring Range	1.3 to 800 mm
Rotary Measuring Range	Fractional turn to ~110 deg, calibration to customer spec
Total Accuracy (Comb: Non-linearity, repeatability, hysteresis)	+/-0.25% FRO (relatively average)
Available I/O's, Frequency Response	Historically: +/-15V DC input, +/-10V DC output; Now 24V DC input, 0-10V DC output is common. Freq Response: Average to Low
Environmental Capabilities: Operating Temp. Range, Pressure, Shock/Vibration	Very high to highest
Susceptibility to External Magnetic Fields	Susceptible to AC fields (dependent upon shielding)
Stroke-to-Length Ratio (Linear Only) (lower is better, 1:1 is ideal)	Generally 2:1 or more in DC-DC form; can be as low as 1.2:1 as layer wound in AC-AC form
Relative Cost to User	Very high; AC-AC requires separate electronics
Application Types	General machinery and process control apps. particularly in most demanding environmental conditions of temperature, pressure, shock and vibration
General Comments	Traditional choice in high performance position sensing…difficult and expensive to build but most rugged…now being superceded where possible in many apps by less expensive and more compact L/RVIT's
