Overview
The NDT161 surface roughness instrument is a small inspection equipment of KAIRDA brand. It adopts a split design and consists of a host, a driver and a Sensor. The instrument is equipped with a large color Touchscreen, supports DSP control and data processing, conforms to ISO, DIN, ANSI, JIS and other standards, can measure the asperity of the inner wall of the pipe with an inner diameter greater than 40mm, and has Bluetooth interconnection, wireless printing and Data storage functions.
Features
1. Small surface roughness detector, split design, composed of host, driver and Sensor, easy to operate.
2.3.5-Inch high-resolution color touch display, with backlight, support Touchscreen and button dual operation.
3. Evaluate Linear dispersion, load Linear dispersion, amplitude distribution Linear dispersion and other Linear dispersion representation functions, and display the calculation results and each interval result.
4. Support USB high-speed communication, Bluetooth APP operation, external Bluetooth printer and SD card large-capacity Data storage.
5. Standard Groove Sensor to meet more than 90% of measurement requirements.
6. Anti-motor dead software/hardware design, extension cable 1 meter can be increased to 3 meters.
Principle
The NDT161 surface roughness meter uses a displacement differential Inductance Sensor to slide on the surface through a diamond stylus (90 taper angle, 5 μm tip radius) to measure vertical and horizontal displacement. The DSP controls and processes the data, using RC, PC-RC, Gauss, D-P filters for signal processing, calculating asperity parameters, and displaying the original profile and Linear dispersion on the display screen.
Applications
Pipeline inner wall asperity measurement, machined surface inspection, industrial quality control, material surface analysis
Standards
ISO4287 international standard, ANSIB46.1 American standard, DIN4768 German standard, JISB601 Japanese standard
Steps
1. Connect the host, driver and Sensor, making sure the extension cable is set as needed (1 meter can be extended to 3 meters).
2. Turn on the power supply and use the built-in lithium-ion battery or DC5V charger to power it.
3. Measurement parameters and standards are selected through Touchscreen or buttons.
4. Place the Sensor on the measured surface, start the measurement, and the Sensor moves at the specified sliding speed.
5. Check the asperity parameters and Linear dispersion results on the display.
6. Use Bluetooth to connect to the APP or printer for data transmission and printing, or store data through USB or SD card.
Notice
• Sensor stylus and guide clean before measurement to avoid contamination affecting accuracy.
• Ambient Temperature should be kept at -20 ℃~ 40 ℃, Humidity less than 90% RH.
• Temperature range -40 ℃~ 60 ℃ during storage and transportation, Humidity is less than 90% RH.
• When using the guide head, pay attention to the radius of 40mm in the sliding direction to avoid excessive pressure.
• Use the designated DC5V, 800mA charger when charging to prevent battery damage.
• Ensure that the Sensor is stably placed when measuring pipes with an inner diameter greater than 40mm.
