Detailed Product Description

1-inch flush mount compatible with a PMC®
process connection, or 11/2-inch threaded
mounting connection
Absolute or gage pressure ranges
from 01.5 to 0300 psi
20:1 turndown
Communicates via the HART® protocol
0.20% reference accuracy, including linearity,
hysteresis, and repeatability;
1-in. flush mount compatible with PMC process
connection, or 1 1/2-in. threaded mounting
connection
The 2090P has process connections that position the
isolation diaphragm flush with vessel or pipe walls,
eliminating clogging problems associated with highly
viscous processes that tend to crystallize,
polymerize, or precipitate, such as those in the pulp
and paper industry.
Absolute or gauge pressure ranges from 0-1.5 to
0-300 psi and 20:1 turndown
Higher turndown allows for lower inventories by
allowing you to measure pressures from 1.5 psi to
300 psi with only three transmitter ranges.
Communicates via the HART® protocol
The 2090P utilizes the advantages of HART
communication, enabling quick and easy reranging,
calibration and troubleshooting.
0.20% Reference Accuracy, including linearity,
hysteresis, and repeatability
The single-filled sensor system of the 2090P leads to
outstanding accuracy due to full sensor
compensation.

Load Limitations
Reverse polarity protection is standard. Maximum loop resistance
is determined by the power supply voltage as described by the
following equation:
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. No vacuum
calibrations are allowed on the 2090P.
Overpressure Limits
Range 1: 120 psig
Range 2: 300 psig
Range 3: 1,600 psig
Temperature Limits
Process: 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 the
ambient limits by a 1.5:1 ratio.
Humidity Limits
0100% relative humidity
Volumetric Displacement
Less than 0.00042 cm3
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≥ 21.75 mA
Low: I ≤ 3.75 mA
NAMUR-Compliant Operation
Linear Output: 3.8 ≤ I ≤ 20.5
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 jumper.
