The UW-12 Underwater Contour Probes is an electromagnet capable of inducing a strong magnetic field in ferromagnetic alloys. The coil is wound on the center body section and then encapsulated in a molded nylon housing using a special polyurethane.
Articulating legs provide for maximum surface contact and allow for precise application of the magnetic field. The lower leg assemblies may be removed for cleaning and oiling.
The upper leg section entering the center body are sealed to prevent water intrusion. A metal strain relief is mounted at the rear and will accommodate a power cable up to a maximum of .420 inches O.D. Each unit comes standard with 3 feet of 16/3 SJOW cable.
The UW-12 operates from a 12V full wave DC, 2.5 amp power supply, with suitable DC isolation from any AC circuits. Pure DC, as from a battery may also be used. Duty cycle is 100%. Currents as low as .3 amps (produced by 4V FW DC across the probe coil) will provide adequate lifting force to meet applicable specification, the same field limitations apply as for the UW-115.
Generally the strongest magnetic field, and most sensitive test is achieved by placing the Contour Probe on the section with both legs squarely in contact with the surface. The test section completes the magnetic loop and maximum flux is available for entrapment. Magnetic particles are induced between the legs with power on. After each use in salt water, wash and dry the unit and lightly oil the legs.
