Silver Emat Ultrasonic Thickness Gage

As an Authorized dealer we are engaged in providing the broad assortment of wide gamut of NDT Instruments.
This is a portable electromagnetic ultrasonic (abbr. asva EMATa ) thickness gauge to be used without couplant or direct contact on materials of metal or magnetism, based on electromagnetic-acoustic transduction.
The main difference of this technology is that the ultrasonic wave is generated directly in the tested object.
Advantages

A. A-scan display with a gatea to distinguish between interface echo, bottom echo and boundary echo, and gauge the thickness value by distance between echoes (dual-gate mode & auto crest), which is the best approach to inspecting objects with multiple layers of different kinds of metal.

A. Optional Time-based B-scan mode to characterize the contour of stair-like objects.

A. Weighing only 1.0kg with battery, a handy instrument saving efforts in on-the-move job.

A. Standard kit includes heat-proof handle, linear scanner, multi-orienting scanner, probe elevator in consideration of possible conditions under which the users work with this instrument.

A. Optional functionalities like RS-485 BUS networking, GPRS wireless communicating and SMS for the users to realize their modern dreams on NDT instruments.

A. High suitability of the probe to work under the temperature ranging from -40a to 300a in general duration, and up to 600a within at-away interval, especially valuable for extreme conditions

1A. Available gauge range 2~300mm with precision up to 0.01mm makes it excel in the EMAT world.

1A. A wonderful substitute for conventional UT instrument to deal with poor coupling conditions such as roughness and rust, without being affected by these factors, saving effort to clear them off.

Also therea s no need to adapt the bottom of the probe to the curvature of the pipe to be inspected.

A. Contactless gauging is allowable by max 3mm away, which makes thickness gauging immune to gapping, obstruction, and possible for metal beneath coating.

1A. Com App will be offered to read the file saved in the instrument and transferred to PC by USB for
further analysis.

EMAT probe (2MHZ, but can be customized to different
specification) that can induce eddy current as to generate ultrasonic wave on the
surface of a metal or magnetic object by permanent magnet and electrified coil.
Strong constitution by solid casing and temp-insensitive element enables this
transducer to function over harsh conditions like coarse-textured interface and
extreme climate (kitted with heat-proof probe cable).

Areas of Application

A.Refrigeration

Heat-proof Handle
A.To effect gauging at a distance
A.To keep the operator away from the object if ita s too hot while doing the job and protected by the adiabatic sock gloved on the grip end from
being scalded.

Linear Scanner

A.Special design of panzer-like appearance with two groups of wheels respectively at the front and the rear to change the spot of probe more
conveniently against its powerful magnetism to the surface of the object.

A. To run the probe more smoothly and quickly over surface with high roughness.

A. To easily control the pace of movement while doing time-based B-scan thickness gauging.

A.To avoid damage to the probe by rugged surface of the object (direct contact)


Multi-orienting Scanner
A.With four metal balls respectively at the bottom of each corner, this scanner enables the probe to be moved and turned in different directions more flexibly.
