Instantaneous
Response
Thermo Fisher’s Dynamic Process Tracking (DPT) ensures there is no lag time in the
system’s response to significant changes in process density. When changes reach a user
set threshold, the DPT feature reduces the normal averaging time constant to a faster,
user-set time constant, ensuring a rapid, smooth output response. When the process
stabilizes, the time constant automatically goes back to the original setting, to reduce
the fluctuations inherent in radiation-based measurements. In this way, process density
changes are immediately reflected in the transmitter output, while the effects of
statistical variations in the radiation measurement are greatly reduced.
Multiple Readouts
Select up to four measurement values for display: density, bulk density, solid and
carrier concentrations, the ratio of solids to carrier, bulk mass flow, bulk volume flow,
and the rate of change of any of these measurements.
Extensive Alarms
Up to sixteen process alarms may be assigned in the system, in addition to system fault
alarms and warning alarms
Totalizers & Batch
Control
A maximum of four independent totalizers can be set to count elapsed time or
cumulative mass/volume when a flow input signal is provided and a mass/volume flow
measurement is defined.
Output Signals
Any measurement can be assigned to the 4–20 mA current outputs, or the
measurement values can be sent to a remote terminal or host computer as serial data.
