TMTECK TC-200 Crack detector
Crack detection has never been easier or more affordable!
Detects and measures surface cracks in steel - even under thick
protective coatings!
Inspect:
Bridges and buildings and other structures
Amusement park rides
Mining and earth moving equipment
Cranes and other lifting equipment
Ships, tanks, military hardware
Pipelines, pressure vessels and oil field equipment
Signal Light Masts, etc.
Features:
Detects cracks under thick coatings
Simple to use
Indicates crack severity (depth)
Accurately find the crack tip
Minimal training required
No need to remove paint and other coatings.
No need to remove oil and grease
Economical
Fast – scan a foot of weld in 10 seconds!
Minimize the use of dye penetrant and magnetic particle
inspection (use only to prove-up test results).
Less expensive than eddy current and ACFM instruments
Light weight – 0.6 lb. (300gr.)
No consumables
No mess
14 hour battery operation
Water resistant case (IP-65)
SET-UP:
Place a plastic shim of similar thickness to your coating on the
test block. Place the probe over a defect free area and press the
“balance” button
Rotate probe so that finger grip is parallel to the notch
Scan the probe over the appropriate notch in the test block and
adjust the sensitivity buttons as required to achieve the required
sensitivity.
OPERATION:
plate and pipe:
Scan the area of interest in a Zigzag pattern, repeat at 90
degrees.
welds:
HAZ
Place the probe over the Heat Affected Zone immediately adjacent
to the weld and scan the length of the weld. Move the probe 1/8”
(3mm) and scan the length of the weld, repeat this process until ½”
(12.5mm) is covered on either side of the weld. Note: the probe
finger grip should be parallel with the weld.
WELD CROWN
Scan the weld crown in a Zigzag pattern. On bare, rough welds, it
is helpful to place a plastic sheet or tape over the weld.
THEORY OF OPERATION:
The probe contains a transmitter and receiver. The transmitter
creates a stable AC
magnetic field in the test material that is disrupted by a crack.
The receiver in the
probe is a proprietary semi-conductor magneto-sensitive device that
detects and
measures the resultant magnetic flux leakage that indicates the
presence and severity of a crack.
