LCMKD

Supported Applications

The Omega LCMKD Series consists of subminiature industrial compression load cells designed for measuring compressive forces. These metric models are engineered to be mounted on a smooth, flat surface and feature rugged all stainless steel construction with high-performance strain gages.

Operating Conditions & Performance

The LCMKD Series operates within an ambient temperature range of -54 to 121°C (-65 to 250°F). The cells provide a nominal output signal of 2 mV/V with an excitation voltage requirement of 5 Vdc (7 Vdc maximum) and a load resistance minimum of 350 Ω. Performance specifications include linearity, hysteresis, repeatability, and zero balance values expressed as percentages of Full Scale Output (FSO):

• Linearity: ±0.25% FSO
• Hysteresis: ±0.25% FSO
• Repeatability: ±0.10% FSO
• Zero Balance: ±2% FSO

The series carries an IP54 enclosure rating and includes a 5-point NIST-traceable calibration along with shunt data (59 kΩ). The unit weight is less than 14 g (<0.5 oz).

Configuration Options

This series offers configurable capacities across standard imperial (LCKD) and metric (LCMKD) designations, covering measurement ranges from 1 kg to 1000 lb or 10 N to 5000 N. The physical dimensions vary by capacity tier:

• Low Capacity (10 to 200 N / 1 kg to 50 lb): D1: 9.6 mm (0.38 in), H: 3.0 mm (0.12 in)
• Mid Capacity (500 to 1000 N / 100 to 250 lb): D1: 13 mm (0.50 in), H: 3.8 mm (0.15 in)
• High Capacity (2000 to 5000 N / 500 to 1000 lb): D1: 19 mm (0.75 in), H: 6.4 mm (0.25 in)

Electrical connection is provided via a standard 1.5 m (5') 4-conductor insulated cable containing an integrated temperature compensation board. The wire color code is defined as RED = +EXC, BLACK = EXC, GREEN = -OUTPUT, and WHITE = +OUTPUT.

Key Product Differences

The series distinguishes between standard imperial models (LCKD) and metric models (LCMKD). Metric model numbers follow the format LCMKD-<CAPACITY>, such as LCMKD-10N for 10 Newton capacity or LCMKD-5KN for 5000 Newton capacity. Specific variants include capacities of 10 N, 20 N, 50 N, 100 N, 200 N, 500 N, 1 kN (LCMKD-1KN), 2 kN (LCMKD-2KN), and 5 kN (LCMKD-5KN). Some variants are available with extended cable lengths, indicated by suffixes such as -10FT. Compatible meters for these load cells include the DPIS, DP41-S, DP25B-S, and iSeries.
