The Western Instruments WS-Series Magnetizing Coil is list of Portable MPI Equipment. These powerful yet extremely light MPI Coils meet many applicable specifications for MPI. The WS-Series use Western Instruments' innovative Capacitive Discharge Power Supply. The unique WS power supply provides the necessary energy pulse to provide an output of 1,200 Amp Turns per inch of ID and more specifically greater than 400 Gauss in the Center of the Coil. These outputs are common to all four models: WS-8, WS-10, WS-12 and WS-14, while all remain under 20 pounds (9kg).

In the Oil well Drilling Business WS-Coils are commonly called Drilco (Drill Pipe Coils), where Drill Pipe is rarely Demagnetized. It is typically the Tools on the Bottom End of the Drilling String that are demagnetized, and where our WD-Series Coils earned their reputation. Drill Pipe Coils pulse about once per second and induce a very high Residual Magnetic Field, into the workpiece.

Model	Description	Comments
WS-8 WS-8K	Pulsed DC Drill Pipe Coil	Pulsed Drill Pipe Coil, with fixed DC output. Using our specialized Capacitive Discharge Power Supply, that pulses once per second. 50% Duty Cycle
WS-10 WS-10K	Pulsed DC Drill Pipe Coil	Strong DC Field like the old Drilco Pulse Coils. WS Coils are activated intermitently with our durable Endrgize Button
WS-12 WS-12K	Pulsed DC Drill Pipe Coil	Strong DC Field like the old Drilco Pulse Coils. WS Coils are activated intermitently with our durable Endrgize Button
WS-14 WS-14K	Pulsed DC Drill Pipe Coil	Powerful DC Pulse, once per second from a our CD (Capacitive Discharge) Power Supply. Results in a strong Residual Field. Meets requirments for an Active Field Inspection
