SL720 Hydraulic Accumulator Installation

Continuous linear sensing to provide feedback of accumulator charge state has never been easier. The SL Series sensor allows for very easy installation onto any piston accumulator, requiring only slight modifications to standard designs. Key benefits of the SL720:

    • Not an LDT - no piston rod needed
    • Fully enclosed, robust design
    • Tolerates piston rotation and minor misalignment errors
    • Can be mounted on gas or oil side of piston
    • Minimal internal modification required (5/16 – 18 thread hole on piston)
    • One sensor works for all lengths 0-6ft (1,830mm)
    • 12 bit resolution (0.5mm/mV)
    • Hammer-proof, washdown-proof signal conditioner
