PMI-SLE
RECTILINEAR DISPLACEMENT TRANSDUCER WITH
MAGNETIC DRAG (analog output)
Applicative characteristics
• The PMI-SLE transducer, is the amplified version of
the PMI-SL, a product designed for all inside cylinder
applications which require a smaller transducer (the
rod diameter is only 12,7 mm).
• The PMI Slim offers the same robustness: stainlessteel body, IP67 protection level, and pressure resistance up to 250 bar (400 bar peak)
• Available with flanged or threaded heads, to guarantee mechanical compatibility with all main cylinder
types
• Patented solution
• Ideal for applications inside hydraulic cylinders,
demanding simple solutions which guarantee measurement repeatability.

INSTALLATION INSTRUCTIONS
• Respect the indicated electrical connections
• When calibrating the transducer, be careful to set the stroke
so that the output does not drop below 1% or rise beyond
99% of the 4/20mA output.
