Probe N-45 is intended for detecting cracks and measuring their depth (detecting stress- corrosive cracks in metal ferromagnetic constructions) even under layer of corrosion and/or protective coating.
Construction of Probe N-45
The Probe N-45 consists of following: metal housing and elements of excitation and reception of magnetic field. Sensor surface contacting with controlled surface is made of zirconium ceramics.
There are two indicators on the probe: red one signalizing about crack and yellow one signalizing about change of thickness of protective coating (or about corrosive damage).
The cable connects sensor and the electronic unit Eddy-current flaw detector ED-45.
Eddy-current flaw detector ED-45 combines magnetic and eddy-current methods for flaws detection, which enables the user to control products with rough corroded surface and to measure through the layer of insulating coating of variable thickness without any additional readjustment.
Objects of control:
- pipes, pipelines,
- oil and gas pipelines,
- vessels, pressure vessels,
- objects of energy production,
- details of structures, machines and mechanisms.
ATTENTION! If you buy only Probe N-45, the Eddy-current flaw detector ED-45 should be sent to the retrofit and alignment.
The principle of operation of the Eddy-current flaw detector ED-45 is based on magnetic-eddy-current method. The Probe N-45 establishes alternating magnetic field. Under its influence eddy currents are excited in the controlled area of controlled object.
These eddy currents establish stray magnetic fields near the crack that are registered by sensor. Simultaneously distance between probe and controlled metal surface is measured by means of alternating magnetic field.
Registration of mentioned parameters enables to measure thickness of protective coating or depth of corrosive damage as well as detect and measure depth of crack regardless of protective coating thickness or depth of corrosive damage.
