LCGD

Supported Applications

The Omega LCGD Series consists of miniature, low-profile compression load cells designed for high stability and reliability in severe industrial environments. These bonded foil strain gage units are engineered to measure compressive force only. The series includes an integral machined load button and is intended for mounting on a flat surface with a diameter at least equal to the D1 dimension specified for each capacity.

These load cells provide 5-point NIST-traceable calibration data upon delivery. They are compatible with specific digital panel meters, including the DPiS, DP41-S, and DP25B-S series.

Operating Conditions & Performance

The LCGD Series operates within a compensated temperature range of 60°F to 160°F (16°C to 71°C). The broader operating process temperature range is -65° to 250°F (-54° to 121°C). Performance specifications include:

• Linearity: ±0.25% FSO (BFSL)
• Hysteresis: ±0.20% FSO
• Repeatability: ±0.10% FSO
• Zero Balance: ±2%
• Safe Overload: 150% of full scale

The electrical bridge resistance is a minimum of 350 Ω foil strain gage. The nominal signal output is 2 mV/V, with an excitation voltage requirement of 10 Vdc. Temperature effects are specified as ±0.009% FSO/°C for zero and ±0.018% READING/°C for span.

Configuration Options

The series is available in both standard (lb) and metric (N) capacities, covering a range from 25 lb to 50,000 lb and 100 N to 200,000 N. All units feature an all-stainless steel construction with an IP65 enclosure rating.

Key configuration parameters include:

• Load Ranges (Standard): 25 lb, 50 lb, 100 lb, 250 lb, 500 lb, 1K, 2K, 5K, 10K, 15K, 20K, 30K, and 50K.
• Load Ranges (Metric): 100N through 200KN in various increments including 1KN, 2KN, 5KN, 10KN, 20KN, 50KN, 60KN, 80KN, and 120KN.
• Electrical Connection: Includes a 1.5 m (5') shielded cable with pigtail end.
• Cable Color Code: +EXC (RED), +SIG (WHITE), -SIG (GREEN), -EXC (BLACK).

Dimensions vary by capacity, affecting the D1 diameter required for proper mounting. For example, 25 to 100 lb models require a #4-40 UNC thread and have a D1 of 1.00 inch (25 mm), while 50,000 lb models utilize a #6-32 UNC thread with a D1 of 3.00 inches (76 mm).

Key Product Differences

The series is divided into two primary model families based on the unit of measurement:

• LCGD Series: Standard models rated in pounds (lb). Model numbers follow the format LCGD-<CAPACITY>, such as LCGD-5K for a 5,000 lb capacity.
• LCMGD Series: Metric models rated in Newtons (N). Model numbers follow the format LCMGD-<CAPACITY>N, such as LCMGD-10KN for a 10,000 N capacity.

Both families share identical performance characteristics and construction materials. The primary distinction lies in the load range designation and corresponding physical dimensions (D1, D2, H, L) which scale with the rated capacity to maintain structural integrity under compression loads up to 50,000 lb or 200,000 N.
