The FN4070 load cell measures the effort generated on the anchor point of seat-belts during crash-tests. It has been specifically designed with a replaceable tongue, so that the load cell can be re-used by simply changing the tongue. It also has a cable output which can be renewed by the crash test technicians to allow for cost-effective, in-house maintenance of the device.

For lower operating ranges refer to model FN4080.
