Introduction
Ideal for difficult sensing applications, this transducer can measure the displacement & proximity of a metal target without physical contact. The measurement is unaffected 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 teflon 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 “plug 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.
