Supported Applications
The Omega LC307 series comprises miniature high-capacity "Top Hat" compression load cells designed for applications requiring minimum space and loads up to 100,000 lb (500 kN). These units are engineered with rugged all stainless steel construction and high-performance strain gages. The design is intended for mounting on a smooth, flat surface.
Operating Conditions & Performance
The LC307 series operates within an ambient temperature range of -54 to 121°C (-65 to 250°F). Accuracy is specified as 0.75% FS BFL, which includes linearity, hysteresis, and repeatability. The load cells feature a nominal output signal of 1.75 mV/V with an excitation voltage of 5 Vdc. Electrical resistance is rated at 350 Ω minimum. Each unit carries an IP54 enclosure rating.
Configuration Options
The series offers standard and metric models across a broad capacity envelope, ranging from 0-250 lb to 0-100,000 lb (0-1 kN to 0-500 kN). Model numbers follow the format LC307 for standard units and LCM307 for metric variants. Key configurable attributes include:
- Capacities: Standard models available in increments from 250 lb up to 100,000 lb; Metric models range from 1 kN to 500 kN.
- Housing Material: Stainless steel construction for all variants.
- Cable and Connection: Includes a 1.5 m (5') 4-conductor cable with an integrated compensation board.
- Calibration Data: Units come complete with 5-point NIST-traceable calibration and 90 kΩ shunt data.
Dimensions vary by capacity, with overall height (H) ranging from 8.1 mm (0.32 in) to 37.3 mm (1.47 in) for standard models, and diameter (D1) spanning 12.7 mm (0.5 in) to 50.8 mm (2.00 in). The series supports optional accessories including the WRS232-USB wireless transmitter, UWTC-1, and UWTC-REC2.
Key Product Differences
The LC307 family is divided into two primary model families based on unit systems:
- LC307 (Standard): Capacities denoted in pounds, with part numbers such as LC307-5K for 5,000 lb capacity.
- LCM307 (Metric): Capacities denoted in kilonewtons, with part numbers such as LCM307-50KN for 50 kN capacity.
Both families share the same "Top Hat" form factor and performance specifications. The series is RoHS compliant and includes NIST Standard certification documentation.
