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.

Does the LC307 load cell transducer meet the requirements of a non-incendive apparatus and thus is it suitable for application use in a Division 2 hazardous location ?

Asked by: GRT365
The LC307 is not rated for hazardous location usage, please see the LCHD-IS load cells for use in a Division 2 hazardous location.

Which surface of the LC-307 load cell would be best held against a stationary surface and which surface is best to apply the load against ?

Asked by: GRT365
The SPHERICAL RADIUS shown on the dimensional drawing on the Datasheet is the loading surface that you would apply the load.

Is there any data about natural frequency of the sensor? I would like to use it for applications requiring high-frequency

Asked by: sowong
These load cells are strain gage based (piezo-resistive) devices designed for static or slow changes in load. For high frequency applications a piezo-electric based device should be used. Omega does not offer piezo-electric based force sensors

This is a follow-up question for Application Engineer JK, regarding Thermal Resistance question. When you said "no" in your original answer, do you mean negligible Thermal Resistance? or did you mean no information is available?

Asked by: GRT365
There is no data available forThermal Resistance for our load cells

What is the minimum load (in lbf or other equivalent unit) that this sensor starts reading? Does it vary depending on the specific dash number? What would be this number for LC307-3K?

Asked by: ControlsEngineer
The sensor does actually start reading at very low loads but you should never rely on the accuracy of the reading in the lower 10% of it's load range. In the case of a 0 to 3000 lbf range load cell this be readings below the 300 lbf range
