Overview The X96S is a family of measurement products that is intended to replace the current X96N and X99 product families. These products: • use nuclear measurement techniques, • support all features of the current X96N and X99 products, • support up to 32 scintillation or ionization detectors, • optional HART interface, • improved user interface options1, • more user functionality, and • more product flexibility.
Basic Concepts Communications The Ronan X96S Density 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.
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 pipe (or vessel) and its process material, and onto the surface of the detector. Some amount of radiation is absorbed by the material through which it passes, and some of the radiation is transmitted to the surface of the detector.
• • • • 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 density.

Quick Start Reference – Calibrating Density What type of calibration is needed? Two types of calibration are available for Ronan’s density gage. 1. Single-point calibration This requires an accurate laboratory analysis of a truly representative sample of one process density. Single-Point Calibration is used as an alternative method when it is not physically or economically practical to vary the process density.

Calibration Calibration correlates the X96S's output to your actual process density. It instructs the microprocessor to read and store the detector counts for a low and high density of process. Once the system is conditioned to recognize the low and high density, it will provide a 4-20 mA output over the entire range of interest. Reference Modes One of your first tasks will be to calibrate the system. The first step in the calibration procedure is to "reference" the gage on some known value.
Calibration Constant The two values, the reference density (do) and the calibration constant (1/ut), are used by the X96N algorithm to calculate process density (d). t ut 1/ut 2" 3" 4" 5" 6" 8" 10" 0.4 0.6 0.8 1.0 1.2 1.6 2.0 2.5 1.6 1.25 1.0 0.825 0.625 0.5 t = mat'l thickness (pipe I.D.) u = absorption coefficient = 0.
High Calibration (Dual Point Calibration) An alternate calibration technique is the "Dual Point Calibration" where samples of TWO different process densities (do1 and do2) are drawn, analyzed, and entered into X96S software. With the addition of a second known density (do2) the X96S software can now compute very accurately the value of 1/ut, which it uses to determine the process density. The calibration procedure also reverses the relationship between detector counts and actual process density.
Single-Point Calibration Procedure As an alternative, the single-point calibration can be used. In that case, the results of the first sampling procedure are used in conjunction with a manually- calculated calibration constant where: 1 µT = 1 . (0.2) (pipe I.D.) (pipe diameter in inches) The calculated result is entered into the system through the Calibrate Menu, Manual Entry Menu. In this alternate method, the CALIBRATION module sequence is NOT used.
Documentation For future reference, document these items: (a) Environmental/process conditions (densities, temperatures, etc.) that influence the reference/ calibration. The next time a calibration is performed, you will need to duplicate the conditions, or account for the differences. (b) All changes made to factory-default settings such as time constant, reference constants, gain, etc. (c) The information from the status displays.
Configuration Ronan ships the Density Monitor System with factory-default software settings. Those settings are responsible for the information that initially appears on the status displays. After installation at your site, you may need to reconfigure the system to fit your application. The goal is to correlate the X96S output with your lab sampling, so the X96S density monitor can replace the time-consuming task of constant manual lab sampling.
Detector Scintillator Detector Description The Ronan scintillation detector consists of three main components: The plastic scintillation crystal, the photomultiplier tube (PMT), and the associated electronics. Scintillation Crystal The crystal used for the Continuous Level Monitor System is polyvinyl toluene (PVT) plastic. The crystal produces light pulses which are proportional to the incident radiation events striking it.
Detector Service the critical components of the electronic circuit and the PMT/Crystal Assembly are aligned before leaving the factory. If any component of the Scintillation Detector is adjusted or replaced, the performance of the entire system will be adversely affected and will require realignment before continued use is possible. Therefore, the scintillation detector IS NOT field serviceable.
ION Chamber Detector/Amplifier Assembly (DET-7471-XXX) Circuit Description Reference: B-6409-K B-9742-K Ronan’s ion chamber detector is filled with an inert high-pressure gas. It uses low-voltage (-15VDC) bias and generates a low-level current proportional to the gamma radiation incident on the detector. The current generated is on the order of 10 A, so an electrometer amplifier is required to convert the current to a lowimpedance, high-level voltage signal.
Servicing the Detector The ion-chamber detector contains pressurized inert gas. The ion chamber itself is not serviceable and must be returned to the factory for service. Instructions follow for “Detector Removal/Replacement.” However, a qualified technician can troubleshoot and service the detector’s amplifier assembly. Instructions follow for that procedure as well. Some precautions are needed when handling the detector/amplifier assembly.
Detector Removal/ Replacement Detector Housing Cap Detector Housing Cable Connector Detector 1) Check NOTES below for illustrations and cautions that apply to your specific equipment. 2) Unscrew cap on detector housing. 3) Unscrew connector on top of detector. 4) Remove detector from housing. 5) Carefully install replacement detector in housing. 6) Screw connector back onto detector. 7) Immediately replace detector-housing cap. 8) Follow instruction to REFERENCE or CALIBRATE new detector.
Removing the Detector Amplifier Circuit Board (CBAY-6102) Follow this procedure to remove the electrometer amplifier circuit board: 1. Remove the amplifier cover by unscrewing the hex socket head cap screws. 2. Remove the MS connector from the amplifier cover. 3. Remove the two 6-32 binding head screws, which secure the amplifier board to the detector. 4. Using a low power (60W) iron unsolder the detector leads to the printed circuit board standoffs.
Replacing the Detector Circuit Board/Connector Assembly Reference: B-6102-K If installing a new electrometer amplifier board, refer to drawing B-6102-K for internal connector wiring and connections to the detectors. Be sure the detector leads are straightened to clear the holes in the new circuit board. Follow this procedure. CAUTION: Excessive twisting or bending can damage the detector leads.
