A long stroke hydraulic accumulator position sensor fully ATEX & IECEx certified, and suitable for both subsea and surface deployments with stroke lengths to 16m.
CPI’s SL5000 Series — ATEX & IECEx certified linear position sensor suitable for both surface and subsea deployment in 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 SL5000 is designed for complete immersion in hydraulic fluid inside a hydraulic cylinder or accumulator. Additionally this sensor will operate in water or sea water and in an air or gas environment. The 52 foot (16 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 subsea capable.
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.
Please see ES-I-XXX and ES-I-XXY in the product drawings tab below when specifying a magnetostrictive sensor for use with the SL5000, or contact CPI customer service for assistance.
