MODEL 2230R, Process Hydrogen Analyzer The safety of personnel is ultimately the responsibility of those who control process conditions. While this instrument may be able to provide early warning of imminent danger, it has no control over process conditions, and it can be misused. In particular, any alarm or control systems installed must be tested and understood, both as to how they operate and as to how they can be defeated.
MODEL 2230R, Process Hydrogen Analyzer SAFETY MESSAGES Your safety and the safety of others is very important. We have provided many important safety messages in this manual. Please read these messages carefully. A safety message alerts you to potential hazards that could hurt you or others. Each safety message is associated with a safety alert symbol. These symbols are found in the manual and inside the instrument.

MODEL 2230R, Process Hydrogen Analyzer 1. DESCRIPTION The Model 2230R Process Hydrogen Analyzer is designed to detect and/or measure hydrogen as a component of a gas mixture. The hydrogen specific solid-state sensing element is designed for ease of use, interface flexibility and true process control. The electronics contains all the circuitry necessary to operate the sensor and present calibrated hydrogen readings to a voltage or current analog output and an RS232 or RS422 digital output.

MODEL 2230R, Process Hydrogen Analyzer 3. OPERATION 3.1 UNIT LOCATION The unit can be mounted in any orientation or position, however vertical mounting (unit above process connection) should be made in process streams containing liquids or potentially condensing gases. 3.1.1 WARNING LABEL Remove sensor tube warning label prior to using the unit. 3.2 MOUNTING Mounting is achieved by securing the sensor tube into the supplied fitting directly in the process piping as shown below.
MODEL 2230R, Process Hydrogen Analyzer 3.3 PROCESS CONNECTION Model 2230R offer a variety of fittings to mate the unit to a process stream. The following table lists our standard fitting selections. Others are available upon request. • ½” MNPT thread • ½” FNPT thread • -8 SAE/MS thread size ... and many other industry standards. 3.4 PROCESS CONNECTION Power (8 to 13 VDC) is connected via the Power/Analog connector as shown in Section 4.1.
MODEL 2230R, Process Hydrogen Analyzer Step 1 2 3 4 3.5 Description Power units on in 5% H₂/N₂ by volume or greater Operate the Model 2230R Analyzer in the 5% H₂/N₂ or greater gas for six hours or longer Check to see if the sensor readings were accurate and stable over that time If the readings are not accurate and stable, condition the sensor in 5% H₂/N₂ or greater gas overnight and perform the Verification and Calibration described later in this manual.
MODEL 2230R, Process Hydrogen Analyzer • • • If the unit gets exposed to extended periods of no H₂ (or some Oxygen), condition the sensor as described in the Start-up section and follow-up with a Field Verification (and Field Calibration, if needed). Effect of pressure: The Model 2230R Analyzer is hydrogen specific and sensitive to only the hydrogen partial pressure in the gas stream. Since changes in total gas pressure will affect the hydrogen partial pressure, they will also affect the sensor readings.

MODEL 2230R, Process Hydrogen Analyzer 5. MAINTENANCE 5.1 CLEANING If the unit is exposed to process streams containing debris, condensates or other material that may collect over the sensor tip then the unit should be removed from the stream periodically and the tip cleaned by a gentle wiping with a clean lint-free cloth or paper. 5.2 CALIBRATION INTERVAL TELEDYNE ANALYTICAL INSTRUMENTS recommends that the system calibration be carried out if the unit fails Verification.
MODEL 2230R, Process Hydrogen Analyzer 5.4 VERIFICATION Verification Interval Verification is a process to compare the sensor output to a known hydrogen concentration. Verifications do not cause any wear on the sensor and can be accomplished as often as desired. The recommended interval to perform Verification depends solely on the user’s desired tolerance for the specific application in question.
MODEL 2230R, Process Hydrogen Analyzer The Model 2230R Analyzer should be conditioned by operation in hydrogen exceeding 5% by volume until stable and taken through the Field Calibration, if exposed to oxygen or operated without hydrogen for an extended period. If the unit continues to exhibit errors in excess of the published accuracy specification and drift rate, please contact TELEDYNE ANALYTICAL INSTRUMENTS for factory evaluation and repair.

MODEL 2230R, Process Hydrogen Analyzer 5.5 CALIBRATION Calibration Interval Calibration is used to correct any offset that exist between the sensor output and a known hydrogen concentration. Calibrations do not cause any wear on the sensor and can be accomplished as often as desired. It is recommended that Calibration be performed if a unit fails Verification. Calibration Procedure IMPORTANT NOTE: During the Calibration process any previously completed Field Calibrations are cancelled.
