Overview
The Qinji CY1 Series Load Cell is a high-stability, precision-engineered strain-gauge-based force transducer designed for static and quasi-static tension and compression measurements in materials testing, industrial automation, calibration laboratories, and quality control environments. Built upon a robust stainless-steel or alloy steel housing with hermetically sealed construction, the CY1 series adheres to fundamental principles of Hooke’s law and Wheatstone bridge signal conditioning to deliver linear, repeatable output across its rated capacity range. Each unit undergoes individual factory calibration against traceable NIM (National Institute of Metrology, China) standards and is supplied with a calibration certificate indicating sensitivity (mV/V), nonlinearity, hysteresis, and repeatability—typically within ±0.05 % FS (Full Scale) for standard configurations. The sensor operates on a standard excitation voltage of 10 V DC and outputs an analog signal of 2.0 ± 0.002 mV/V nominal, compatible with most commercial data acquisition systems, universal testers, and PLC-based control interfaces.
Key Features
- Wide capacity range: 10 N to 500 kN, covering applications from micro-force characterization to heavy-duty structural verification
- Hermetically sealed design with IP67 ingress protection rating for reliable operation in humid, dusty, or mildly corrosive industrial settings
- Temperature-compensated strain gauge elements minimizing thermal drift (< ±0.01 % FS/°C typical)
- Integrated overload protection up to 150 % FS for enhanced mechanical durability
- Low-profile, low-height geometry optimized for integration into compact test frames and custom fixtures
- Standard M6, M8, M12, or custom threaded mounting options; optional side-load compensation and dual-axis alignment features available upon request
- Compliant with ISO 376:2011 for calibration of force measuring instruments and aligned with ASTM E4 and ASTM E74 practices for verification and use in materials testing
Sample Compatibility & Compliance
The CY1 series supports direct mounting to tensile test specimens, hydraulic/pneumatic actuators, load frames, and automated assembly stations. Its axial loading configuration ensures minimal bending moment error when installed with proper alignment—recommended via parallelism verification using dial indicators or laser alignment tools. All units are manufactured and tested in accordance with GB/T 15515–2019 (Chinese national standard for load cells) and meet essential requirements of the EU Measuring Instruments Directive (MID) Annex MI-004 for non-automatic weighing instruments where applicable. For regulated environments—including GLP-compliant laboratories and GMP-managed production lines—the CY1 can be integrated into systems supporting audit-trail-capable software and documented calibration intervals per ISO/IEC 17025 requirements.
Software & Data Management
While the CY1 is an analog-output transducer requiring external signal conditioning, it is fully interoperable with industry-standard DAQ platforms including National Instruments (NI CompactDAQ, PXI), Keysight (formerly Agilent) 34970A/34972A, and Dewesoft X. When paired with Qinji’s optional Q-Link digital interface module (sold separately), users gain access to real-time digital readout, zero/balance functions, tare memory, and RS-485/Modbus RTU communication for SCADA integration. Calibration data—including date, reference standard ID, uncertainty budget, and environmental conditions—is stored in human-readable format and exportable as CSV or PDF for internal record retention and regulatory review. Traceability documentation satisfies FDA 21 CFR Part 11 compliance when deployed within validated systems featuring electronic signature controls and change management protocols.
Applications
- Universal testing machines (UTMs) for tensile, compressive, and flexural property evaluation per ISO 6892-1, ASTM D638, and EN 10002-1
- In-line force monitoring in robotic welding, riveting, and press-fit assembly processes
- Calibration laboratory transfer standards for secondary force calibration up to Class 0.05 accuracy class
- Structural health monitoring of civil infrastructure components under static load validation
- R&D testing of adhesives, composites, elastomers, and biomedical devices requiring sub-newton to multi-kilonewton resolution
- Education and training platforms for mechanical engineering and metrology curricula
FAQ
Is the CY1 series certified for legal-for-trade use?
No—standard CY1 units are intended for industrial measurement and laboratory testing only. Legal-for-trade certification (e.g., OIML R60 Class C3/C4) requires additional type evaluation and marking; contact Qinji technical support for certified variants.
Can I use the CY1 with third-party amplifiers or controllers?
Yes—provided the amplifier supports 10 V DC excitation and accepts 2 mV/V nominal output with appropriate filtering and noise rejection (e.g., 60 Hz notch, low-pass cutoff ≥100 Hz).
What is the recommended recalibration interval?
Annual recalibration is advised under normal usage. In high-cycle or high-stress applications, semi-annual verification against a traceable standard is recommended per ISO/IEC 17025 Clause 7.7.
Does Qinji provide OEM labeling or private branding?
Yes—custom labeling, packaging, and documentation services are available under NDA for qualified OEM partners meeting minimum order volume requirements.
