The FN4070 seat buckle load cell can be easily re-used by 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. Consult your TE representative for technical specification. With many years of experience as a designer and manufacturer of sensors, we often work with customers to design or customize sensors for specific uses and testing environments. To meet your needs we also offer complete turnkey systems. The matched components (sensor, power, amplifier and digital display) are formatted, calibrated and ready for immediate use.
