线性设计。300系列本质上是线性的。传感器的输出有一个非线性曲线拟合前通常不到1%。这最小化了密度驱动错误发生在气体测量校准气体。曲线拟合修正。数字300系列使用曲线拟合技术来删除任何剩余的非线性系统来提高整体精度。这大大提高了%的阅读错误流率时的一小部分控制器的全面流动。灵活的电力需求。数字300系列可以与任何电力供应能力提供11 - 36 VDC之间的高、低供应别针。15伏直流双极±12 VDC,±或单极24 VDC生病是可以接受的。 COLOR TOUCH PANEL DISPLAY. The Digital 300 Sériés has an optional integrated touch panel color LCD display. This gives the user easy configurability and local control over the instrument. DIGITAL COMMUNICATIONS. The Digital 300B Sériés is equipped with RS232, RS485 and USB for digital communications. The USB connector serves as a Virtual COM port for serial communication, eliminating the need for a USB to Serial converter. ANALOG EMULATION. The Digital 300 Sériés instrument can be set up to mimic an analog instrument. In this configuration the flow output is available as an analog signal and flow controllers will respond to analog commands. AUTO-ZERO. The Digital 300 Sériés of flow controllers can re-zero automatically. This feature is enabled by default at the factory. Auto-zeroing will occur whenever the command signal is set to zéro for 1 minute after flowing for 10 ten minutes. driven zéro shifts. 8.5 lb (3.9 kg)
