X96SI/R Radiometric Transmitter
The X96SI/R is a family of measurement products that replaces the current X96S product fami-
lies. These products offer:
Support for all features of the current X96S products
Newer measurement techniques
Integral mounting with detector, or may be mounted remotely
Patented optical coupling which enables compatibility with a the Ronan Flex or rigid crystal
Scintillation Detector
completed easily through the user’s PC
Menu-driven operation for simple programming
Support for up to 15 scintillation detectors
State-of-the-art transmitter-based electronics provide precision gauging. Built-in intelligence
provides a range of features including:
Automatically compensates for vapor density changes, foam or gasses, process build-up
Automatic source decay compensation
Auto calibrates at multiple points
Radiation discrimination protection against x-rays
Data logging and event recording
Adjustable time constant
Ronan Transmitters provide an array of outputs including:

Radiometric Systems
A Radiometric Measurement System consists of a gamma source and holder, detector and
transmitter. The gamma source is mounted externally to the vessel and emits energy through
the vessel walls, directed towards the detector, also mounted externally, on the opposite side of
the vessel. The gamma energy reaches the detector in an inversely proportional relationship to
the level of material in the vessel. The detector measures the amount of energy and sends a
signal to the transmitter, which interprets the signal into a measurement, and displays the infor-
web interface and on the LCD of the transmitter.
On applications where varying process densities can affect the level measurement, an addition-
al detector is added to the system to compensate for the density changes (Figure 1). The same
detector that is used for the compensation can also be used to make a density measurement.
The gauge can also compensate for non-linear responses due to unique vessel shapes, varying
wall thickness, and obstructions in the vessel.
Because the entire system mounts externally to the vessel or pipe, it can be easily installed and

Interference and noise in measurement readings are eliminated because system compo-
nents do not come into contact with the process material
Component wear and maintenance are reduced because the system does not come into
contact with the conveyor and process material
System is easy to calibrate

vantages. Gamma radiation by Ronan products does not make the
process material radioactive, nor does it change or affect the mate-
rial as it is attenuated.

Ronan offers a wide variety of source holders, including the point source
holder which is mounted to the external surface of the process vessel. A
small slot in the lead shielding of the source holder focuses an active radia-
tion beam through a collimated opening, into the process vessel, and to-
ward the detector which is mounted on the opposite side of the vessel.
To ensure a safe way of closing off the active radiation beam during ship-
ping, installation and servicing, a handle with a rotating shutter is provided.
shielding the radiation beam. This can be either a rotating shutter in front of the capsule, or by
moving the source capsule away from the opening of the lead shield, or by retracting the source
rod back into the source shipping container.
When OFF, or closed, the shutter rotates in place to cover the small opening and shield the ra-
diation beam. The ON, or open, position removes the shielding from the small opening.
Detectors
The Ronan detectors are enclosed in protective housings. When radiation from the source
strikes the “active” length of the detector, a signal is generated. The active length of the elon-
gated detector corresponds to the full measurement range of interest, and is designated by
bands of tape at the top and bottom of the detector housing. Typically, the density measurement
uses a smaller active length scintillation than the continuous level measurement.
Scintillation detectors use a phototube that senses the light produced by the detector crystal,

X96SI/R Transmitter
Ronan’s X96SI/R Transmitter converts the signal from the detector
into the desired measurement and displays the results in a use-
ful format. Through its liquid crystal display screen, and pre-pro-
grammed menus, the process level is continuously monitored with
minimal operator effort. For those monitoring the system through the
web interface, live data is available at the click of a mouse.
The X96SI/R uses the CPU module X96-3001-1 for scintillation
detectors.

All CPU/IO module types are capable of plugging into the same slot in the X96SI/R mother-
board.
Three types of optional daughter boards are available:

The interconnect cables provide a signal from each detector to the X96SI/R Transmitter. The
cables are supplied with a pre-wired MS connector.
