Ultrasonic wall thickness gauge Delta TT 100

Product catalog summary

Overview: The DELTA TT100 is a handheld ultrasonic wall thickness gauge designed for fast and accurate measurement of both metallic and non-metallic materials. It is suitable for various industrial applications, including monitoring pipes and pressure vessels for corrosion or erosion.

Key Features:

Fast and accurate wall thickness measurement.
5 preset sound velocities for different materials.
Stores up to 10 readings.
Robust design with easy calibration.

Applications: The device is used for measuring the thickness of materials such as aluminum, titanium, plastics, ceramics, and glass. It is applicable in industries for measuring raw materials, component parts, and assembled machinery.

Technical Specifications:

Measuring range in steel: 1.0 mm to 225.0 mm with a 5 MHz transducer.
Minimum thickness for steel tubes: 3 mm with a 200 mm diameter.
Display resolution: 0.1 mm with an accuracy of ± 0.1 mm.
Sound velocity range: 1000 to 9999 m/s with a resolution of 1 m/s.
Working temperature: -15°C to +150°C.
Power supply: 2 x 1.5 V AA batteries with approximately 250 hours of battery life.
Dimensions: 126 mm x 68 mm x 23 mm; Weight: approx. 250 g including batteries.

Principle of Operation: The device uses ultrasonic wave pulses transmitted by a probe. These pulses reflect back upon reaching interfaces within the material, allowing the device to measure thickness by calculating the travel time of the waves.

Supply Schedule: The DELTA TT100 is supplied with a plastic case, probe, coupling agent, and instruction manual.

Typical Sound Velocities: The document provides a table of sound velocities for various materials, such as aluminum (6380 m/s), epoxy resin (2600–2840 m/s), and steel (5940 m/s), noting that actual velocities may vary based on material composition and conditions.

Additional Features: The device includes automatic gain control, V-path error correction, a 4-digit LCD display, and a built-in probe zero block for enhanced accuracy.
