Ideal for difficult sensing applications, the Non-Contact LVDT measures the displacement and proximity of a customer-supplied metal target without physical contact. The measurement is unaffected by interposed nonmetallic, non-conductive materials, such as polymers and biomaterials. The stainless shell houses two coils; one for sensing and one for temperature compensation. 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 or saline solutions.
