May 1, 2014 - Pepperl+Fuchs introduces PMI40-F90-U-V15 and PMI40-F90-I-V15 linear inductive sensors offer a 40 mm distance measurement ideal for vertical valve measurements. PMI linear measurement sensors are an ideal replacement for standard cylindrical analog sensors because they deliver greater linear range, linearity and accuracy. With these new models, PMI linear inductive sensors are now available with linear ranges of 14mm, 40mm, 80mm, 104mm and 120mm to satisfy a wide range of sensing requirements.
Unlike cylindrical analog sensors, PMI sensors do not measure changes in distance so the vibration and machine tolerance of the vertical valve do not affect position and accuracy. As a result, the PMI provides an advantage in improving the overall accuracy of a machine’s processes.
The optimal distance from PMI40 to the standard sensor target (BT-F90-W) is 2mm, but an available sensing range of 0.5 to 3 mm delivers accurate linear position regardless of the sensing range. The 40 mm linear distance delivers 33 um resolution. The shorter housing of the PMI40 enables it to be applied where models with longer housings are unsuitable.
