Basic Concepts
Communications
The Ronan X96S Level gage provides both 4-20 mA current loop and HART communications.
4-20 MA
For many years, the field communication standard for process automation equipment has been a 4-20 mA current loop
signal. The current varies in proportion to the process variable being represented. In typical applications, a signal of
4mA will correspond to the lower limit (0%) of the calibrated range and 20mA will correspond to the upper limit (100%)
of the calibrated range. Thus, if the system is calibrated for 1 to 3 feet, then an analog current of 12mA (50% of range)
will correspond to a level of 2 feet.
HART
HARTField Communications Protocol extends the 4-20mA current loop standard to enhance communication with
smart field instruments. The HART protocol was designed specifically for use with intelligent measurement and control
instruments which traditionally communicate using 4-20mA analog signals. HART preserves the 4-20mA signal and
enables two-way digital communications to occur without disturbing the integrity of the 4-20mA signal. Unlike other
digital communication technologies, the HART protocol maintains compatibility with existing 4-20mA systems, and in
doing so, provides users with a backward compatible solution. HART Communication Protocol is well established as
the "de facto" industry standard for digitally enhanced 4-20mA field communication.
The enhanced communications capability of intelligent field instruments employing the HART protocol, offers
significantly greater functionality and improved performance over traditional 4-20mA analog devices. The HART
protocol permits the process variable to continue to be transmitted by the 4-20mA analog signal and additional
information pertaining to other variable, parameters, device configuration, calibration, and device diagnostics to be
transmitted digitally at the same time. Thus, a wealth of additional information related to plant operation is available to
central control or monitoring systems through HART communications.
Variables
There are two types of variables, communications variables and device variables.
Communication Variables
HART defines four device variables, PV (Primary Variable), SV (Secondary Variable), TV (Tertiary), and QV
(Quaternary). PV is assigned to the primary 4-20 ma loop. HART is also communicated over this loop. SV is assigned
to an optional secondary 4-20 ma loop.
Device Variables
The Ronan X96S Level gage has 2 device variables:
Device Variable

Configuration Variables
The Ronan X96S Level gage has many configuration variables that are accessed through its menus.

Theory
Theory of Radiation Gaging
Radiation gages operate on the principle of radiation absorption and transmission.
A beam of gamma radiation is directed from the source holder, through the vessel and its process material, and onto
the surface of the detector.
Radiation which is not absorbed by the material through which it passes, is transmitted to the surface of the detector.
Process measurement is possible because the amount of radiation absorbed and transmitted is predictable.
The absorbed radiation is directly related to the level of process material in the vessel while the transmitted radiation is
inversely related to the level of process material in the vessel.
Therefore, an increased process level results in a decrease of transmitted radiation.
Since the radiation that's not being absorbed is being transmitted, the process level can be inferred by measuring the
amount of radiation reaching the detector at any point in time. The detector's output signal, in counts, also varies
inversely to the process level.
When the process level is low the detector is exposed to a maximum amount of radiation which produces a HIGH
output of counts. When the process level is high the process material "shields" the detector and prevents radiation
from reaching the detector, producing a LOW output of counts.
The X96S Microprocessor converts the detector signal to user's measurement units of level: m, mm, cm, in, ft.
The X96S displays the output measurement range in the selected user units. The "zero" of the measurement range
represents the lowest level of interest, while the "span" of the measurement range represents the highest level of
interest.
Reduction of the signal "noise" due to radiation statistics is handled in the stage of signal processing known as digital
filtering. Digital filtering is a form of statistical averaging used to smooth, or dampen, random radiation as well as
process-related noise. Increasing the digital filter’s “time constant” decreases signal noise.
Dynamic tracking permits the gage response to temporarily by-pass the digital filter. This is helpful in some processes
where sudden or drastic step changes in process must be observed in their true, or unfiltered, state.
Software also compensates for the decay of the radioactive source activity. On-going adjustments are made
automatically for the rate of decay, or source half-life.

Principles of Operation
The detector's raw output signal is processed through several stages of software in the X96S.
Some of the more significant stages of signal processing are:
Units Conversion – conversion of counts into user-selected level units
Measurement Range – 4-20 mA output defined by the user-selected range in user-selected units.
Digital Filtering – signal smoothing to reduce statistical radiation noise
Dynamic Tracking – quick gage response to quick process changes.
Source Decay Compensation – automatic compensation for the radioisotope decay
Calibration (Referencing) – calibration of gage to user process.
The Calibration (or Referencing) procedure relates detector output (in counts) to numeric values that accurately
represent the actual process level.
The level algorithm used by the X96S software is a simple transfer function. That is, the relationship between the
detector output and the process level is mathematically expressed as:
