To achieve high accuracy, a balance must compensate for the influence of temperature fluctuation at the force sensor. The temperature range of a tuning fork based balance is extremely small. This is due to the tuning fork sensor's superior heat capacity and conductivity. The DETF vibrator requires a very small amount of excitation energy, allowing it to have very simple temperature and heat transfer characteristics. Additionally, the tuning fork sensor doesn't require any A-D converters, analog circuits, or magnetic circuits which cause complex temperature vibrating-plate characteristics. This allows Rice Lake balances to maintain incredibly long-term stability. Since the tuning fork sensor measures force by reading changes in resonant frequency, the possibility of hysteresis is practically eliminated. Features:
