A neutral density filter (ND filter) is a light filter that decreases the intensity of light without altering the relative spectral distribution of the energy. An ND filter is used to filter the entire visible spectrum evenly, allowing light reduction, without influencing color or contrast. (read more)

The Columbia S Series LVDTs are designed to sense linear displacement over the ranges of +/-0.04" to +/-0.30" and translate this motion into a precisely proportional voltage for measurement and control. (read more)

GW Lisk Linear Variable Differential Transformer (LVDT)can be utilized in a wide variety of applications wherever position feedback is important. (read more)

LVDT's are inductive displacement transducers that have proven themselves as very robust and particularly suitable for use in installations where high vibrations, high accelerations and/or very long cycle lifes are to be expected. Even oscillations with small sweeps, and measurements under 1mm can be achieved. Displacement ranges from 2mm to 200mm are available. (read more)

FN 256 filters are designed specifically for applications involving asymmetric loads, ranging from industrial controls to medical electronics systems. (read more)

A 3-phase, low zero sequence impedance autotransformer, which when connected near to and in parallel with the harmonic generating non-linear loads (usually connected at the distribution panel), provides an alternate path for 3rd, 9th, & 15th current harmonics (triplens) which the loads create. Patented Field Adjustable Impedance (FAI) feature allows for adjustment of NCE™ zero sequenc... (read more)
