Abstract

The United States National Institute of Standards and Technology (NIST) has been developing a new device for primary standard realization of torque utilizing established trace- ability to the quantum-electrical International System of Units (SI) standards following the 2019 revision of the SI. This device, the Electronic NIST Torque Realizer (ENTR) is a self-calibrating device with the goal of outperforming current commercial torque transducer uncertainty levels, improving torque tool calibration at low torque ranges, and shortening the torque standards dissemination chain. This project's goal is to create a device for torque calibrations with an operational range of 7 × 10−4 N m to 1 N m with an uncertainty at or below 0.1 %. We intend ENTR to be a possible replacement for current transfer standards used in the torque standards dissemination chain, easing the financial and logistical burdens of current torque standards dissemination systems.
