1 Product Data Sheet Absolute and Gage Pressure Transmitter ATRADITION OF EXCELLENCE IN THE PULP AND PAPER INDUSTRY Mounts flush to process media -inch flush mount compatible with a PMC process connection, or /2-inch threaded mounting connection Absolute or gage pressure ranges from 0 to psi Optional scaleable LCD meter Communicates via the HART protocol 20: turndown on smart option External zero and span adjustments 0.20% reference accuracy, including linearity, hysteresis, and repeatability Over 35 years of experience and the finest network of service and support in the industry Stable, reliable, and easy to maintain NEW OFFERING! PROVEN ROSEMOUNT RELIABILITY AND STABILITY The Rosemount Pressure Transmitter provides stable, reliable service for applications that require flush mounting to the process media. The was designed by Rosemount Inc., the most trusted name in process control, for the pulp and paper industry and similar applications where process clogging is aconcern. ONE-INCH FLUSH MOUNT PROCESS CONNECTION Rosemount Inc. now offers aone-inch flush mount option on the Smarttransmitter. This new option is compatible with a PMC process connection, and requires no retrofitting for existing one-inch fittings. Simply remove the old transmitter and replace it with the new one. When you replace your old transmitter with the new,high performance one-inch flush mount transmitter, not only do youget superior Rosemountperformance, youget it with practically no installation costs. 22 Pressure-22

2 Absolute and Gage Pressure Transmitter Introducing the One-Inch Flush Mount Fitting Now you can have superior Rosemount technology without having to retrofit a new transmitter. The new smart transmitter with the one-inch flush mount process connection can be installed in any existing one-inch flush mount fitting without the cost of replumbing. The one-inch process connection is also available with a weld-on nipple assembly option for new installations. If your old system has the standard one-inch flush mount design, there has never been a better time to upgrade to Rosemount technology. The with the one-inch flush mount process connection comes equipped with these standard features: Easy Installation for existing one-inch mounts 3-hole rotational mounting flexibility HART communication compatibility 0 50 psi with 20: rangeability Local zero/span or remote calibration capability Viton O-ring for use with a wide variety of process fluids Optional LCD meter for local display of process pressure SUPERIOR FUNCTIONALITY The design incorporates a process connection that positions the isolating diaphragm of the transmitter flush with the vessel wall. This design eliminates clogging problems associated with traditional transmitters used in highly viscous processes that tend to crystallize, polymerize, or precipitate, such as those in the pulp and paper industry. Its small size and rugged, in-line construction make it ideal for paper mill applications on stock lines, refiners, screens, cleaners, vacuum boxes, and vented tanks. SUPERIOR ROSEMOUNT DESIGN Two-compartment housing provides a junction box for easy access to test terminals and RFI protection, and a separate airtight electronics housing which allows easy replacement of the circuit board. Optional LCD meter. Provides readout directly from the transmitter (See Figure 2). The Rosemount has these technologically advanced features: HART protocol compatibility. The Model 2090P has full smart communication capabilities via the HART Communicator. Microprocessor-based circuitry ensures excellent performance by optimizing sensor linearity and reducing the external influences of temperature. Each transmitter is factory characterized to deliver exceptional performance. Unique silicon-based resistance sensing element is a Rosemount-patented thin-film, polysilicon sensor that guarantees excellent performance and stability in harsh environments (see Figure ).

3 Rosemount Inc. Zero Elevation and Suppression Zero can be suppressed between atmosphere (2090PG), or 0 psia (2090PA) and upper range limit, provided the calibrated span is equal to or greater than the minimum span, and the upper range value does not exceed the upper range limit. The Model 2090PG, in either the analog or smart versions, does not do vacuum calibrations. FIGURE 2. One-Inch Flush Mount Option with Optional LCD Meter AB Overpressure Limits Range : 20 psig.

Maximum loop resistance is determined by the power supply voltage as described by the following equation: Max. Loop Resistance = 43.5 (Power Supply Voltage 0.5) Load (ohms) Operating Region Power Supply Output S (dc Volts) () For hazardous location approvals, power supply must not exceed 36 V. Humidity Limits 0 00% relative humidity. Volumetric Displacement Less than cm 3. Turn-on Time 2.0 seconds, no warm-up required. Failure Alarm If self-diagnostics detect a sensor or microprocessor failure, the analog signal is driven either high or low to alert the user. High or low failure mode is user-selectable with a jumper on the transmitter. The values to which the transmitter drives its output in failure mode depend on whether it is factory-configured to standard or NAMUR-compliant operation. The values for each are as follows: Standard Operation linear output:3.9 I 20.8 fail high:i 2.75 ma low:i 3.75 ma NAMUR-Compliant Operation linear output:3.8 I fail high:i 22.5 ma. low:i 3.6 ma. Transmitter Security Activating the transmitter security function prevents changes to the transmitter configuration, including local zero and span adjustments. Security is activated by an internal switch. 223 Pressure-223
