Eddy Current Far Field Probe For Heat Exchangers Ferromagnetic Tubes

Eddy Current Far-field Probe for Heat Exchangers Ferromagnetic Tubes

The eddy current sensor is based on the principle of electromagnetic induction. It generates an alternating magnetic field through a coil. When approaching a conductive object, the magnetic field will induce eddy currents on the object's surface. The reverse magnetic field produced by the eddy currents will change the impedance of the coil. By measuring the impedance change, the characteristics of the object being measured can be inferred, such as surface cracks, material sorting, thickness measurement, etc., making it suitable

Eddy current probes are classified into internal penetration type, external penetration type and point type. According to different industry application scenarios, the appropriate classification probes are selected. Their application scenarios are extensive, covering multiple industrial fields.

1. Aerospace: It is used to detect cracks on the surface of turbine blades and compressor blades.
2. Petrochemical industry: It is used to detect corrosion and cracks on the inner and outer walls of pipelines transporting oil, natural gas and chemicals.
3. Power industry: It is used for the detection of heat exchange tube bundles in heat exchangers and surface crack detection of steam turbine blades.
4. Automobile manufacturing: It is used to detect cracks on the surface of engine blocks, crankshafts and valves.
5. Railway transportation: It is used to detect surface cracks and wear on train wheels, rails and turnouts.
6. Nuclear industry: It is used to detect oxidation and cracks in nuclear power plant pipelines.
7. Shipbuilding: It is used to detect surface cracks and corrosion of weld seams in ship hull welding.

   Application scenarios	The probe is mainly applied to ferromagnetic tubes in heat exchangers, heat exchanger tube bundles and other pipelines. It can effectively detect cracks, corrosion and wear, and provides two excitation modes: dual excitation and single excitation.
   Product Features	The stainless steel shell is wear-resistant and reduces the usage cost for customers.We offer domestic production of imported probes, with faster delivery times and more favorable procurement costs.
