Abstract

Tuning fork type load cells are expected to have better long-term stability than conventional strain gauge type load cells. A new 50 N rated capacity load cell has been developed herein adopting a Double-Ended Tuning Fork (DETF) sensing unit. The performance of two such load cells was evaluated using the 500 N force standard machine at the National Metrology Institute of Japan (NMIJ). The DETF load cells were found to have low creep, low hysteresis and superior long-term stability.
