MT190 Multi-mode Ultrasonic Thickness Gauge



MT190 multi-mode ultrasonic thickness gauge, based on ultrasonic measuring principle, it can perform thickness measurements on a wide range of materials including metals, plastic, ceramics glass and other ultrasonic well-conductive materials. It is also capable for measuring the sound velocity of the object with known thickness. 

Compared with the traditional measurement method, the advantage of ultrasonic thickness gauge is that it can finish the measurement only if it contacts with one side of the measured workpiece. Its unique performance of capable for testing thickness through the coating provides efficient solution for testing the workpiece of coated surface or corrosion materials. It can test the workpiece directly without needing to get rid of the surface coating. Widely used for monitoring the production equipments’ various pipelines and pressure vessel corrosion reducing degree in the fields of petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and so on. It also can be used for making accurate measurement to various plates and machining parts. It is the necessary professional precision instrument for improving the production efficiency and qualification rate as well as saving cost.

The digital ultrasonic thickness gauge determines the thickness of a part or structure by accurately measuring the time required for a short ultrasonic pulse generated by a transducer to travel through the thickness of the material, reflect from the back or inside surface, and be returned to the transducer. The measured two-way transit time is divided by two to account for the down-and-back travel path, and then multiplied by the velocity of sound in the material. The result is expressed in the well-known relationship: H=v×t/2  

Where: H-Thickness of the test piece. 

               v-Sound Velocity in the material. 

               t-The measured round-trip transit time. 

Multi-mode: Pulse-Echo mode and Echo-Echo mode.

Capable of performing measurements on a wide range of material, including metals, plastic, ceramics, composites, epoxies, glass and other ultrasonic wave well-conductive materials.

Transducer models are available for special application, including for coarse grain material and high temperature applications.
