Product Description: Rosemount Pressure Transmitter 2090


Accurate, stable, and reliable pressure measurements for the Pulp and Paper Industry 1-inch flush mount compatible with a PMC®process connection, or 11/2-inch threadedmounting connectionAbsolute or gage pressure rangesfrom 01.5 to 0300 psi20:1 turndownCommunicates via the HART® protocol0.20% reference accuracy, including linearity,hysteresis, and repeatability;1-in. flush mount compatible with PMC processconnection, or 1 1/2-in. threaded mountingconnectionThe 2090P has process connections that position theisolation diaphragm flush with vessel or pipe walls,eliminating clogging problems associated with highlyviscous processes that tend to crystallize,polymerize, or precipitate, such as those in the pulpand paper industry.Absolute or gauge pressure ranges from 0-1.5 to0-300 psi and 20:1 turndownHigher turndown allows for lower inventories byallowing you to measure pressures from 1.5 psi to300 psi with only three transmitter ranges.Communicates via the HART® protocolThe 2090P utilizes the advantages of HARTcommunication, enabling quick and easy reranging,calibration and troubleshooting.0.20% Reference Accuracy, including linearity,hysteresis, and repeatabilityThe single-filled sensor system of the 2090P leads tooutstanding accuracy due to full sensorcompensation.Functional SpecificationsServiceLiquid, gas, vapor, and high-viscosity applicationsRangesOutput420 mA dc/Digital HART ProtocolRangedown20:1Load LimitationsReverse polarity protection is standard. Maximum loop resistanceis determined by the power supply voltage as described by thefollowing equation:Zero Elevation and SuppressionZero can be suppressed between atmosphere (2090PG), or 0 psia(2090PA) and upper range limit, provided the calibrated span isequal to or greater than the minimum span, and the upper rangevalue does not exceed the upper range limit. No vacuumcalibrations are allowed on the 2090P.Overpressure LimitsRange 1: 120 psigRange 2: 300 psigRange 3: 1,600 psigTemperature LimitsProcess: Codes A & C: 40 to 250 °F (40 to 121 °C)Codes D & G: 4 to 250 °F (20 °C to 121 °C)Ambient: All Codes: 4 to 185 °F (20 to 85 °C)Storage: All Codes: 50 to 185 °F (46 to 85 °C)Process temperatures above 185 °F (85 °C) require derating theambient limits by a 1.5:1 ratio.Humidity Limits0100% relative humidityVolumetric DisplacementLess than 0.00042 cm3Turn-on Time2.0 seconds, no warm-up requiredFailure AlarmIf self-diagnostics detect a sensor or microprocessor failure, theanalog signal is driven either high or low to alert the user. High orlow failure mode is user-selectable with a jumper on thetransmitter. The values to which the transmitter drives its output infailure mode depend on whether it is factory-configured tostandard or NAMUR-compliant operation. The values for each areas follows:Standard OperationLinear Output: 3.9 ≤ I ≤ 20.8Fail High: I≥ 21.75 mALow: I ≤ 3.75 mANAMUR-Compliant OperationLinear Output: 3.8 ≤ I ≤ 20.5Fail High: I ≥ 22.5 mALow: I ≤ 3.6 mATransmitter SecurityActivating the transmitter security function prevents changes to thetransmitter configuration, including local zero and spanadjustments. Security is activated by an internal jumper.Performance Specifications(Zero-based spans, reference conditions, and 316 SST isolatingdiaphragm.)Reference Accuracy±0.20% of calibrated span.
