Engineered for Precision and Accuracy

LISK LVDTs (linear variable differential transformer) and RVDTs (rotary variable differential transformers) are designed and manufactured for use in the most demanding environments.

Field Proven Experience

LISK’s sensors can be found on nearly every aircraft in service today. From aerospace to oil and gas our team has a deep understanding of the demands on LVDTs and RVDTs in the field whether it’s in the air or on the ground. Our team of engineers is dedicated to your success and will work with you to execute an LVDT or RVDT design that meets your requirements and environmental conditions.

Our engineers reference your unique application to determine the function, interface, environment, and size requirements.


LVDTs or linear variable differential transformer is a type of electrical transformer used for measuring linear position. Key specifications for our LVDTs include:

  • Strokes of .010″ to 24″ and beyond with accuracy better than 0.5% of full scale range
  • Single channel and multi-channel (up to 6 channels) designs
  • AC and DC inputs and outputs
  • Ability to accommodate high pressures and wide temperature extremes
  • Part count can be reduced by using customer interfaces and mountings to match any application


RVDTs or rotary variable differential transformer is a type of electrical transformer used for measuring angular position. Key specifications for our RVDTs include:

  • High reliability and repeatability
  • Compatible with -55° C to 200° C continuous exposure
  • Compatible with 250° C to 1000 cumulative hours before electrical performance degradation
  • 80° operating range with ±0.4° accuracy
