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.

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.

Will the Platinum Series or DP 25B-S digital panel meter work with the 500 lbf load cell?

How short can the cable that comes with the load cell be? It's really long for our application. Thank you.

Asked by: datsunzcr
Standard cable length is 20'. We suggest you simply coil up the cable and secure it. Do not cut the cable. This could possible effect the calibration and it will void the warranty.

I am looking for a load cell to verify the load in tension of knots and splices in synthetic cables for rigging and rescue work in human life support. The MBS of the rescue lines go between 5000 and 8000mbs. Test table is electric winch operated.

Is the thread count and diameter same for all joints?

Asked by: Aneesh
Aneesh, thank you for contacting Omega Engineering. I believe you are asking about the internal thread count on the load cell. Each load cell will have its own thread size and count based on the range. If you are looking at the LC103B-500 the threads will be 1/2-20UNF. If you need more information kindly email pressure@omega.com

Were can I find the datasheet/pin-out/color coding etc?

Asked by: Ivy27
LC113B models < 300 lbs uses 4-pin connector, and LC113B models > 300 lbs use 6 pin connector. Pin out will be: 4 pin : A = + Out B = - Out C = -Input D = +Input 6 pin : A = + Out B = - Out C = -Input D = +Input E and F = NO CONTACT One of our Application engineers has reached out to you regarding this case, in case you need more assistance feel free to reach us at 1800 622 2378

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.
