PMT ALPHA Arm: Precision measurement with multiple performances meets the diverse demands

Preface

PMT Technologies is the first high-tech company of its kind in China that breaks down barriers to core technologies of portable coordinate measuring machine and aspires to accelerate domestic substitution for imports of high precision and ultra-high precision 3D measurement instrument and software. As the staple product in PMT, ALPHA series measuring arm has remarkable features, innovative design and different grades of accuracy, setting a new benchmark in portable measurement field.

PMT ALPHA series arm adopts the internal counterbalance system and equal-length joint design that are most suitable for on-site measurement. It has simple and balanced structure, flexible operation, and bold innovation in details. The material of joint body is aerospace carbon fiber, which effectively enhances the machine’s thermal stability.

Each arm has passed rigorous tests such as Extreme Temperature Cycling (-20℃~60℃) and Shock and Vibration Testing per International Electrotechnical Commission(IEC) Standard. In accordance with ISO10360, PMT measuring arm has passed strict accuracy verification to ensure consistency of precision and reliability of the measurements in various environments.

Additionally, ALPHA arm can be connected to computers or other devices via its wired or WIFI networks to enable data synchronization and data management. All arms other than the E series are available in 6 - and 7-axis to adapt to different applications of inspection.

This article will give an in-depth introduction of four grades of accuracy in ALPHA series (P/M/E/EDU), and fully display the unique charm from multiple perspectives including measurement range, measurement error, basic configuration and optional accessories.

01 ALPHA P: Flagship arm series

PMT ALPHAP, the flagship series arm, has ?premium accuracy and excellent performance, ensuring customer’s leading position in quality control.

In order to measure workpieces with different sizes, ALPHAP 6-Axis measuring arm offers seven different working volumes from 1.5m to 4.5m, while ALPHAP 7-Axis offers six working volumes from 2.0m to 4.5m.

Not least, ALPHAP 7-Axis can be installed with HD(high-level) or SD(standard) scanning head, providing a perfect solution to the problem that contact probe cannot touch precisely the special-shaped surface.

02 ALPHA M: Standard arm series

PMT ALPHAM, the standard series arm, is the best choice for customers who are looking for a stable, reliable and reasonably priced ?inspection solution used in factory or shop-floor.

The M series has 6- and 7-axis to choose from, same with the P series. The 6-axis arm is suitable for general measurement needs, while the 7-axis arm with an extra axis greatly enhances the flexibility of operation and work efficiency.

As to the measurement range of ALPHAM 6- and 7-axis, customers can refer to the above. Likewise, ALPHAM 7-Axis can be equipped with either HD or SD scanning head for non-contact measurement.

03 ALPHA E: Value-for-money choice

PMT ALPHAE series arm offers customers great value for money. As the staple of this series, ALPHAE 6 AXES focuses on reducing costs while maintaining accuracy.

There are seven measurement ranges including 1.5m, 2m, 2.5m, 3m, 3.5m, 4m and 4.5m. The measurement accuracy and working volumes are sufficient to meet daily measurement requirements, making it ideal for companies looking for a cost-effective price.

04 ALPHA EDU: Best choice for the education sector

PMT ALPHA EDU series arm is designed for educational institutions to support them playing their part in making greater contributions, promoting innovation and boosting productive forces.

Schools are free to choose ALPHA arms with different measurement ranges, as well as contact or non-contact types according to different teaching purposes. This will help students sharpen their competitive edge in the manufacturing sector and scientific research fields.

At present, PMT has joined hands with top universities and vocational schools to embark on a new journey of bringing together firms, universities, and research institutes to engage in cross-field and in-depth cooperation. The cooperated educational entities include Southeast University(SEU), Tongji University, Shanghai Jiao Tong University, Nanjing University of Science and Technology(NJUST), Jiangsu University of Science and Technology, Anhui Polytechnic University(AHPU), Anhui University of Science and Technology(AUST), Taiyuan University of Science and Technology(TYUST), Duzce University, Taizhou Vocational and Technical College, Hubei Industrial Polytechnic, Dongfeng Technician College of HuBei Province, and Sanming University.

In conclusion, with different accuracy selections and outstanding performances, PMT ALPHA arms provide different measurement solutions for customers from various fields.

From the flagship P series to the cost-effective E series to the EDU series for education sector, each product reflects PMT’s profound accumulation of technologies and innovation capabilities in the field of portable measurement technology.

Going forward, PMT will continue to contribute greater R&D and innovation capabilities to the development of measurement technology, and provide customers with more comprehensive and precision measurement solutions.
