Dual Bridge Compression Load Cells 📰19th Nov 2021
These recently despatched load cells are on their way to a supplier of products and services used in drilling operations. The load cells have two independent sets of strain gauges that provide completely separate signal outputs for sensor redundancy, so that in the unlikely event of one failing, the second can be used to maintain system integrity. This is typically required for safety critical applications, particularly relating to the oil and gas industry. They have also been fitted with SubConn connectors and have been pressure tested to 10 Psi for complete protection against water ingress. Although the same external dimensions, two of the load cells are rated at 170klbf (77 tonnes) and the other two at 800klbf (363 tonnes), and each provides an accuracy of 0.5% of rated load.
