3-parameter hyperlattice™ database for the permeability and thickness of a steel plate, and sensor lift-off

Measurement Grid, Lattice, and Hyperlattice™ Databases

MR-MWM-Array responses are converted into material or geometric properties using measurement grid, lattice and hyperlattice databases. Measurement grids are two dimensional databases of sensor responses and lattices are three dimensional (see Figure at left). These grids and lattices are used to convert the sensor response into the unknown properties of interest, such as pipe wall thickness, electrical conductivity, magnetic permeability, and lift-off (i.e., sensor proximity to the weather jacket) using JENTEK’s multivariate inverse methods.

Piping & Vessel / Tank Wall Inspection Scanners

Adaptable for multiple diameters

Automated or manual and encoded for C-scan imaging

Minimal complexity

Light weight

Easy to use by operators

MR-MWM-Array Sensors

JENTEK’s sensor arrays are designed and fabricated so their response to varying coating/ insulation and piping/vessel wall properties matches the response computed using physics-based models. The MR-MWM-Array sensor uses magnetoresistive sense elements that provide an improved signal-to-noise ratio at low frequencies. This MR-MWM-Array is used for deep penetration applications, such as the characterization of internal and external corrosion through insulation, to measure remaining wall thickness.
