AI-Powered supplier vetting

SummaryAnhui Qidian Automation Technology Co., Ltd. is a high-tech industrial automation supplier founded in 2011. It offers broad customization, 3D software design, ODM/OEM services, SDK support, and documented R&D processes. Its portfolio includes signal isolators, safety barriers, transducers, level sensors, and digital pressure gauges. Stated production capacity is 100,000 pieces each for level transmitters and pressure transmitters, with standardized finished-product inspection. The supplier reports ISO9001:2015, RoHS, CE, and FCC certifications, documented complaint handling and corrective-action procedures, and overseas installation, debugging, maintenance, repair, and training services. Innovation evidence is mixed because the supplier reports no new products in the past year, although it maintains R&D engineers, technical documentation, and development capabilities. No financial information or Fortune 500 customer collaboration is provided.

Supplier typeThe supplier describes itself as a high-tech enterprise specializing in industrial automation and intelligent solutions, with products including signal isolators, safety barriers, electrical and pressure transducers, liquid-level sensors, and digital pressure gauges. This supports classification as an industrial automation equipment and component manufacturer.

CertificationsThe supplier reports RoHS, CE, FCC, and other product compliance certifications, as well as an ISO9001:2015 management-system certificate. The slices explicitly document multiple product and quality-system certifications.

After-Sales capabilityTechnology engineers provide technical support for production and after-sales service, while overseas offerings include debugging, maintenance, repair, training, and equipment installation. Complaint handling, supplier-service assessment, and corrective/preventive-action procedures are documented and followed, indicating an established service process.

Production capacityReported annual productivity is 100,000 pieces each for level transmitters and pressure transmitters. The supplier has high- and low-temperature alternating and aging facilities, standardized finished-product inspection instructions, a stated off-season and peak-season lead time within 15 workdays, and documented quality assurance and traceability.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also offers 3D software design, ODM, OEM for popular brands, SDK availability, and states that products can be customized to customer specifications.

Client casesThe supplier identifies Canton Fair participation and states that it offers overseas services in locations described as the United Nations and Russia. It explicitly reports no collaboration with Fortune 500 companies, and no named customer cases or verifiable project references are provided.

Product Q&A

Q:How can I measure both level and temperature simultaneously with only one mounting hole?

We can customize an integrated level and temperature transmitter to achieve dual measurement through a single hole, solving the problem of limited installation space.

Q:How do I choose a signal isolator?

You need to confirm three points: 1 Input signal type (current / voltage / frequency); 2 Output signal type (4-20mA / RS485); 3 Power supply voltage (24VDC/220VAC) and whether explosion-proof certification is required. Please provide the parameters, and we will assist with free product selection at Anhui Qidian Automation Technology Co., Ltd.

Q:Do the products have explosion-proof or CE certification?

Isolation safety barriers, pressure/level transmitters, and other products all have explosion-proof and CE certifications. Electronic copies of the certificates are available upon request.

Q:What should I do if the instrument has no display when powered on?

1. Check if the supply voltage (24VDC/220VAC) is normal and if the positive and negative terminals are connected correctly; 2. Check if the terminal blocks are loose or have poor contact; 3. Confirm that the power supply meets the requirements; 4. If the display remains blank after verifying the above, contact after-sales service for return inspection.

Q:What causes inaccurate or highly fluctuating measurement data?

1. The installation location is subject to strong vibrations or electromagnetic interference; relocate the instrument or ground it. 2. Incorrect parameter settings (range, turndown ratio, scale factor); recalibrate. 3. Sensor scaling or damage; clean or replace the sensor. 4. Mismatched medium properties (e.g., electromagnetic flowmeters require conductive media).
