Control Products Inc. of East Hanover New Jersey has introduced its SL series linear position sensor line for hydraulic cylinders and accumulators. The new products represent a major evolution in the durability of sensors used in harsh environments and are designed to drop-in replace other types of hydraulic cylinder position sensors in the field. For long stroke or telescoping cylinders used in high temperature, high vibration, or underwater environments, these sensors outperform and outlast all other traditional sensor technologies, and are a drop in replacement for failure prone magnetostrictive “rod-type” sensors.
