    Chapter 1 Product Overview Introduction The Thermo Scientific SGD-O system consists of a radiation source in a lead-filled housing, an ion chamber detector with an amplifier, and the SGD-O transmitter. The transmitter processes the detector signal to provide a signal output proportional to the density of the slurry, the mass of solids added per volume of carrier, or both.

  • Page 16: The Detector

    The Transmitter The SGD-O transmitter is a microprocessor-based system that processes the signal from the detector (0–10 Vdc) to provide an output signal (4–20 mA) representing the amount of solids (proppant) added per volume unit of carrier and/or the bulk density of the slurry.

  • Page 17: Inputs & Outputs

    Two optional relay outputs can be provided on each I/O board. Note If the detector will be connected directly to customer equipment (i.e. the SGD-O transmitter will not be used), the detector output is 0 to 10 Vdc.  Thermo Fisher Scientific...
