    产品详情
    参数
    包装
    • Load cell & Strain Gage Amplifier
    • MV to Current/Voltage Conversion
    • Front-Programmable/LED Display
    • Relative Calibration of Input Span
    • NPN/PNP Input for External Taring
    • Supply for Standard Transducers

      • Brand New DRST-BG MV Signal Transmitter converts bipolar mV signals from transducers supplied directly by the device to standard current/voltage signals.

      Application
      DRST-BG is suitable for load cell application as well as otherapplications such as tank filling and draining, weighing with ataring function, measurement of cable tensile force, levelcontrol, signal conversion/amplification.
      Advanced Features
      A multifunction user interface consisting of three push buttonsand a 3-digit LED display for programming.
      Technical Characteristics
          • Front error LED.
          • The analog input can be programmed for voltage in the range -40 to 100 m Vdc.
          • The digital signal can be selected as either NPN or PNP. Taring can either be by way of the digital input or from the front interface.
          • The analog output can be programmed to current in the range 0 to 20 mA or voltage in the range     • Short circuit protected transducer supply which can beprogrammed to 5 to 13 Vdc from the front.
          • Sense input (with transducer supply used) for compensation for cable resistance to the transducer.
          • Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate.
