Sensors (LVDT)

Defense Sensors (LVDT)

LISK manufactures customized LVDT sensors for the DoD that are used in missiles, satellites, submarines and military aircraft. We are considered to be one of the top suppliers for customized sensors worldwide.

We design position feedback sensors with sensing strokes of 0.010” to 24” and beyond. Lisk designs offer robust construction to withstand rigorous environmental conditions such as thermal changes, vibration and shock. LVDT designs can withstand temperatures up to 375° F (190° C) *Contact us for higher temperature applications*. All internal cavities are filled with proven encapsulant, providing protection from vibration and moisture ingress. Within the sensor, there’s no contact between the moving core and sensor body, which helps maintain high performance over its service life.

Fixed Wing Aircraft:

  • Fighters: F-35 (JSF), F-22, F-18, F-15, EF-2000, AM-X, LCA
  • Trainers: Hawk 100/200, M346

  • Cargo: CH-53K
  • Multi-Purpose: NH-90, H-92, S-92

Flame Arrestors

Defense Flame Arrestors

Our flame arrestors are used in fuel inerting systems, fuel venting systems, electrical panel protection (sealed or vented), explosive environment protection, in-flight refueling systems, and many more.

Custom designs and the most demanding challenges are our specialty. Standard (platform) designs to meet demands for reduced engineering time, reduced lead time and lower cost are also available.

Advantages Include:

  • Unique manufacturing processes eliminate hardware from the flow path, and reduce the weight and cost of the component
  • Diameter designs customized to meet your specified need
  • Sealed, end-of-line flame arrestors fitted with a burst disc for foreign body protection
  • Designed to meet customer and environmental requirements as well as as well as RTCA DO-160 or MIL-STD-810 (where applicable)
  • Designs that meet or exceed standards in (NEC Gas Groups: A, B, C, D or (IEC) Groups: IIA, IIB (3), IIC
