Ideal for diffi cult sensing applications, this transducer can measure displacement & proximity of a metal target without physical contact. The measurement is unaff ected by interposed nonmetallic, non-conductive materials, such as polymers and biomaterials.The stainless shell of the device houses two coils; one for sensing and the other for temperature compensation. The coils and tefl on cable are mounted on a stable PEEK substrate. This assembly is potted into the stainless housing using high-grade, vacuum-pumped epoxy and includes integral strain relief.This packaging allows the sensor to be used in applications requiring long-term immersion in water and saline solutions.Miniature Γplug and play signal conditioners provide linear DC output when supplied with unregulated DC power. Multichannel, OEM and digital display systems are also available.Custom ranges are available on request. ? available with sub-micron resolution? operating temperature to 175 ԰C ? frequency response up to 20 kHz ? stainless steel and high-performance polymer design suitable for extremely harsh environments? waterproof, suitable for submersion in corrosive media such as brake fl uid and hot saline? non-contact design suitable for high duty-cycle applications? easily customized to suit specifi c application > ? miniature control elements in automotive and robotic systems ? process control for production-line monitoring ? measurement of tissue deformation and implant micromotion in biomedical studies? materials science, civil engineering: structural defl ections,strain extensometry? optical components: linear/angular positioning ? miniature sensors: force, torque, acceleration >
