SL2000 Internal Mount Safety Rated Linear Position Sensor - 32 ft (10 Meters)

SL2000 Internal Mount Safety Rated Linear Position Sensor – 32 ft (10 Meters)

A long stroke hydraulic accumulator position sensor fully ATEX & IECEx certified, and suitable for both wet and surface deployments with stroke lengths to 10m. The sensor combines high accuracy with responsiveness in a long-stroke environment. Commonly used for telescoping cylinder position measurement or hydraulic accumulator charge measurement/monitoring.

Description

CPI’s SL2000 Series is the first ATEX & IECEx certified linear position sensor suitable for deployment inside or outside long stroke hydraulic cylinders and accumulators.

By coupling short-stroke magnetostrictive sensors to our patented linear-to-rotary-to-linear draw wire measurement technology, we leverage the significant advantages of each technology, with none of the drawbacks. Since only a short probe (rod) is required, we eliminate typical concerns related to rod sagging due to shock and vibration, rod deflection, and end of stroke dead zones while dramatically extending linear sensing capability. Like our LVDT based version of this sensor, the entire technology is non-contacting.

Like all SL Series sensors, the SL2000 is designed for complete immersion in hydraulic fluid inside a hydraulic cylinder or accumulator. Additionally this sensor will operate in a wet environment or an air or gas environment. The 32 foot (10 meter) sensing range is achieved using our proven SL Series linear-to-rotary-to-linear technology, scaled up and packaged in a strong aluminum and stainless steel frame incorporating a robust and unique draw wire assembly. The Sensor can be specified with a shielded cable or integral connector of any specification, including submersible cable connectors.

ATEX / IECEX Certification

All of the highly developed configurations and certifications achieved by magnetostrictive sensor manufacturers are now available for challenging long-stroke applications, where installing a rod-type sensor is not practical or even possible. Leading manufacturers including MTS offer virtually any intrinsic safety rating for the most demanding applications. See these representative product data sheets from MTS that feature typical ATEX, IECEX and SIL ratings.
