Small in size but not in performance, the Series LC307 "Top Hat" load cell is designed for applications with minimum space and high capacity loads up to 100,000 lb. Rugged all stainless steel construction and high performance strain gages assure superior linearity and stability. Temperature compensation is achieved through a miniature circuit board in the load cell’s cable. This unit is designed to be mounted on a smooth, flat surface.

The LC307 is also available in metric configurations, with 0-1 to 0-500 kN ranges. Please see the LCM307 for complete details, or contact our Pressure department for more information..

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.

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

Regarding "top-hat" load cell item LC307-500 lbf.; Please advise if you can provide the following information - A) What is the Maximum Power (Watt) Rating for this device B) What is the Thermal Resistance of the Device (degrees Celsius per Watt)

Asked by: GRT365
Power ratings for this .cell are a follows. Nominal Excitation Voltage is 5 VDC. Maximum current from power supply 15 mA. There is no for Thermal Resistance on this sensor.

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.

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

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
