Rated 1 out of 5 by from Incorrect Part & Extra Costs Due to Website Error Issue with Order: We experienced a significant issue with our order due to an error in the website's part identification system. This error led to the receipt of an incorrect part, which was not only inconvenient but also added unnecessary costs to our project. Cost Impact: The mistake resulted in an additional expense of $300 over our original budget. This overcharge was a direct consequence of the website error, placing an unforeseen financial burden on our project. Incorrect Part Received: Instead of the PigTail part we initially ordered, we received a connector. This mix-up was further complicated when the representative provided us with the wrong part number during our attempt to resolve the issue. Overall Experience: The combination of the website's identification error, the additional costs, and the receipt of the wrong part has been highly disappointing. It has caused delays and financial strain on our project, which could have been avoided with a more accurate and reliable ordering system. Recommendation for Improvement: We urge the supplier to review and improve their website's part identification process to prevent such errors in the future. Clearer communication and more accurate assistance from customer service representatives would also be beneficial.

Does this load cell need to be in-line with the force in tension? Or can it be in parallel? Meaning off to the side

Asked by: JG Lisko
The load cell needs to be in-line with the applied force

The LC101 page says that series is being replaced by the new and improved LC103B series. What is improved? LC103B appears to have greater error (linearity, hysteresis, repeatability) but is bi-directional for less than half the cost. Is that it?

Asked by: Indiana_tester
You are correct. Combined accuracy calculation for LC103B does work out to 0.060% opposed to 0.037% of the LC101. We should consider calling this load cell a more economical replacement of LC101 rather than an improved version.

My lab apparatus, including a stirrer, motor and measuring equipment (sensors) weighs about 50 - 60 kg. The mass of feed material (plastic and sand) is about 200 g. I want to measure the mass drop (1 g or less) as vapor forms. Would that be possible?

Asked by: RALS
Thank you for your questionT Please feel free to give us a call at (203) 359-1660 or email pressure@omega.com and we would be happy to discuss your specific application and provide you with the right product for your specifications.

What does the output +/-3mV/V mean? does it mean that for an excitation voltage of 9V the maximum output is +/-27mV?

Asked by: irf20
thanks for the inquiry That is correct. This unit is ratio metric therefore as the excitation changes so would the total output.

Is this load cell compatible with a National Instruments chassis? Does this load cell require a special DAC?

Asked by: lnidl
This load has an internal 3mV/V sensitivity full strain gage bridge. NI offers input boards designed to take this type of input. We do not know the exact model number of this input board so you have to check with NI directly

Is the Factory Calibration good for the life of the Load cell or is it recommended to have the sensor calibrated on any interval?

Asked by: Anonymous
Hello, we recommend sending in the load cell for recalibration one year from the time of installation. you may contact us at cservice@omega.com for calibration and returns.
