Inductive surface tracing principles in AR-132B profilometers

Portable roughness testers Amittari Instruments / Anmiao AR-132B employ an inductive probe to trace micro-geometry on machined surfaces. A natural diamond stylus with a five-micrometer tip radius glides over the test workpiece under a constant four-millinewton gauging force.

Mechanical stylus deflections are converted by an inductive transducer into electrical signals, which undergo DSP filtering via RC, PC-RC, and GAUSS algorithms to separate machine vibrations from roughness parameters Ra, Rz, Rq, and Rt.

Values appear on the backlit digital display and store directly into non-volatile memory.

Digital signal profile filtering in SRT-6210 instruments

Digital surface roughness instruments Amittari SRT-6210 incorporate a high-speed DSP processor for mathematical roughness evaluation. The processor calculates arithmetic mean roughness Ra and ten-point height Rz across standardized cutoff lengths of 0.25 mm, 0.8 mm, and 2.5 mm.

An alloy steel calibration specimen with documented roughness values enables rapid sensitivity adjustment of the measuring circuit before critical quality verification runs. The detachable probe simplifies alignment within bore holes, narrow grooves, and spindle components.

Abrasive blast profile evaluation aligned with ASTM D4417-B

Specialized roughness testers Amittari AR-131A assess peak-to-valley micro-irregularities on structural steel following grit or shot blast cleaning. In alignment with international standard ASTM D4417-B, the gauge records anchor pattern heights up to 800 micrometers.

Establishing a verified surface profile height is essential to ensure coating adhesion and prevent premature corrosion beneath protective polymer systems. The durable tungsten carbide contact tip maintains geometry when positioned against abrasive blast-cleaned steel plates.

Pulse-echo ultrasonic thickness measurement in AT-140 gauges

Ultrasonic thickness gauges Amittari AT-140 employ the pulse-echo method to evaluate transit times of ultrasonic sound waves traversing solid metallurgy. A dual-element transducer transmits an acoustic wave through couplant into the wall and receives the echo returning from the back wall surface.

Utilizing the sound propagation velocity of the tested alloy, the unit computes residual wall thickness from 0.75 to 400 millimeters, uncovering internal corrosion pits without taking pressurized piping networks out of service.

Combined magnetic induction and eddy current methods in AC-990

Dual coating thickness gauges Amittari AC-990 combine two testing methodologies within a single universal sensor. Over ferrous steel substrates, the gauge utilizes magnetic induction to evaluate non-magnetic protective layers including zinc plating, enamel, and paint.

When placed on non-ferrous conductive metals like aluminum, brass, or copper, the instrument automatically switches to eddy current mode to assess dielectric layers, anodizing, and varnishes without manual configuration.

Three-axis vibration machinery diagnostics with AV-160D meters

Portable three-axis vibration testers Amittari AV-160D provide comprehensive mechanical assessment of rotating machinery.

An external piezoelectric accelerometer measures vibration synchronously across orthogonal X, Y, and Z axes, detecting shaft misalignment, impeller unbalance, and rolling element bearing defects.

The unit determines vibration acceleration, velocity, and displacement in conformance with ISO 10816 and ISO 2954 reliability guidelines, while magnetic mounting ensures secure attachment to machine housings.
