EMAT Air Coupling Electromagnetic Thickness Gauge
General introduction
The instrument adopts the principle of electromagnetic ultrasonic, and there is no need to grind the surface of the workpiece during the detection process, and no coupling agent is required
The probe and the host are integrated, and the probe can be replaced
Configurable probe types: normal temperature probe: ≤ 120 ℃, 4MHz, mainly used to detect fine-grained materials, such as low carbon steel, aluminum, etc., with a maximum liftable distance of 4mm, high temperature probe: ≤ 800 ℃, 4MHz, mainly used to measure ferromagnetic fine-grained materials, such as low carbon steel, with a maximum liftable distance of 2mm
Lift-off effect: (actual lift-off distance is related to material properties and degrees), anti-rust film, salt deposits or any other insulating coating (oil, varnish, porcelain, plastic, etc.) can be used as operating clearance
Features
# Pocket pen type, no coupling agent, and non-contact thickness gauge
# Human body engineering design, compact structure, super small volume, easy to carry, hand-held operation, strong magnetic absorption, improve fatigue conditions
# Accurate thickness measurement, can pass through the coating, professional algorithm program support, do not need to coupling agent, do not need to grind the workpiece surface, allow the detected surface paint and wrapping layer, allow the workpiece surface uneven
# Multi-material sound velocity can be pre-stored in the instrument, and the material sound velocity can be dynamically added and deleted at the same time. The sound velocity calibration increases the temperature compensation function, and effectively improves the measurement accuracy
# Corrosion layers are allowed and the measurement can be improved with a maximum increase distance of 3mm
# The minimum diameter (curvature) of the workpiece that can be detected is 8mm
# The maximum tilt angle of the probe: 25°
# Probe excitation method: water magnet
# Type of sound wave: shear wave
