FAQ-----------------------------------------------------------------------------------
1. Do you have any minimum order quantity limit for load cell?
One piece for sample checking is available, but the sample price is high. In the mass production, unit price depends on the rough idea of Qty., the more the better.
2. What is a load cell and where can I find the explanation of the used terminology?
Load cell is an electrical instrument which is used to convert a mechanical force into an electrical output signal. The terminology for load cells can be found in the OIML R60 regulation for load cells.
3. Will load cells be supplied with a calibration certificate?
All of our load cells will be supplied with a unique calibration certificate with the values determined during the production process.
4. How do I connect a 4-wire load cell to a 6-wire connector?
When connecting a 4-wire load cell to a 6-wire connector, two bridge wires are necessary to connect the wires properly. These bridge wires should be connected between the Exc+ and the Sig+ and the other wire between the Exc- and the Sig-. Please look at the user manual for this solution in practice
5. Are you a trading company or a factory?
We are a group company specialized in the R&D and manufacture of weighing equipment for 12 years. Our factory is located in Ningbo, China. You can come to visit us. Looking forward to meeting you!
