Overview
The Sartorius OEM Standard Series L/LC load cells are precision force-sensing modules engineered for seamless integration into pharmaceutical machinery, dispensing systems, automated assembly lines, robotic end-effectors, and industrial weighing platforms. Built upon Sartorius’ proprietary SuperMonoBloc® sensor technology—a monolithic aluminum alloy strain gauge architecture—these load cells deliver exceptional long-term stability, minimal creep, and high reproducibility under dynamic and static loading conditions. Unlike traditional multi-component sensor assemblies, the SuperMonoBloc® design eliminates internal mechanical interfaces, reducing hysteresis and thermal drift while enhancing signal integrity. The L/LC series is specifically optimized for OEM applications requiring compact form factor, robust environmental resilience, and compatibility with embedded control architectures. All models feature an integrated bottom-mounted hook for tension or hanging-load configurations, enabling versatile mounting in space-constrained equipment layouts.
Key Features
- SuperMonoBloc® monolithic aluminum alloy sensing element ensuring structural homogeneity and intrinsic temperature compensation
- Hermetically sealed anodized aluminum housing (IP65-rated) for resistance to dust, moisture, and mild chemical exposure
- Integrated lower hook for bidirectional force application—supports both compression and tension measurements without external adapters
- LC variants include internal automatic calibration (IAC) circuitry compliant with ISO 9001 traceable self-check routines
- Low-profile, modular mechanical interface with standardized M3/M4 threaded mounting holes for rapid system integration
- Factory-calibrated output: ±0.02% FS linearity, ±0.01% FS repeatability (typical), with mV/V analog output (2.0 ± 0.1 mV/V at rated load)
- Operating temperature range: –10 °C to +40 °C; compensated range: 15 °C to 25 °C
Sample Compatibility & Compliance
The L/LC series is designed for direct integration into GMP-compliant pharmaceutical manufacturing equipment—including tablet press feeders, liquid filling nozzles, capsule sorters, and gravimetric loss-in-weight (LIW) feeders. Its construction adheres to ISO 80000-4 (mechanics), EN 10204:2004 Type 3.1 material certification standards for aluminum alloys, and meets electromagnetic compatibility requirements per EN 61326-1:2013. While not standalone metrological instruments, these load cells are supplied with individual calibration certificates (traceable to NIM, China) and support audit-ready documentation packages required under FDA 21 CFR Part 11 and EU Annex 11 for computerized system validation. The LC models’ internal calibration function satisfies periodic verification intervals defined in USP and Ph. Eur. 2.2.2.
Software & Data Management
These load cells operate as analog transducers and do not incorporate onboard firmware or digital communication protocols. Integration requires external signal conditioning—typically via Sartorius-compatible junction boxes (e.g., YK-200 series) or third-party PLC analog input modules supporting 24-bit ADC resolution. For OEMs developing proprietary HMI or MES interfaces, Sartorius provides comprehensive technical documentation including pinout schematics, excitation voltage specifications (10 V DC ± 0.1%), zero-balance tolerance (±2% FS), and temperature coefficient data (≤0.002% FS/°C). Calibration data files (CSV format) and certificate templates are available upon request to support IQ/OQ documentation workflows.
Applications
- Gravimetric dosing in continuous manufacturing of oral solid dosage forms
- Real-time mass monitoring in syringe fill-finish systems
- Force feedback control in collaborative robot (cobot) grippers for delicate part handling
- Dynamic load measurement in vibration-dampened packaging conveyors
- Inline weight verification in checkweighers integrated with vision-guided sorting
- Process analytical technology (PAT) frameworks compliant with ICH Q8(R2) and Q9
FAQ
Are these load cells certified for use in sterile manufacturing environments?
No—while the housing meets IP65, full sterilization (e.g., SIP, autoclaving) is not supported. For aseptic applications, consult Sartorius’ dedicated HyLine® hygienic load cell series.
Can the internal calibration (LC) be triggered remotely via digital command?
No—the LC function is manually initiated via dedicated hardware jumper or momentary switch input; it does not support Modbus or EtherNet/IP triggering.
Is NIST-traceable calibration included with shipment?
Each unit ships with a manufacturer’s calibration certificate traceable to China’s National Institute of Metrology (NIM); NIST-traceable calibration is available as a value-added service upon order specification.
What is the recommended excitation voltage and maximum cable length?
Rated excitation is 10 V DC; maximum recommended shielded twisted-pair cable length is 30 m using 24 AWG copper with 90% braided shielding to maintain signal-to-noise ratio above 72 dB.
