Rose mount Pressure Transmitter 4500 Series

Detailed Product Description

Hygienic design conforms to 3-A and EHEDG
standards
The hygienic design of the Rosemount 4500 feature
15 μ-inch Ra mechanically polished and 10 μ-inch
Ra electropolished wetted surfaces and an all
stainless steel design that is free of voids and
crevices to ensure easy cleaning and wipedowns.
The 4500 is also 3-A authorized, EHEDG approved
and designed according to strict ASME BPE
guidelines.
Demonstrated best-in-class performance
during SIP/CIP for process temperatures
up to 400ºF (204ºC)
The 4500 was designed and thoroughly tested to
ensure that not only does the 4500 minimize
temperature induced errors from SIP/CIP processes,
but that it also recovers rapidly. This can reduce your
downtime between cleaning cycles, enabling faster
turnarounds and increased plant availability.
Proven, trusted Rosemount technology improves
process reliability and robustness
The Rosemount 4500 uses the same proven sensor
and electronics technology found in other industry
leading Rosemount products ensuring that the
transmitter is robust and reliable, improving your
process reliability and increasing plant availability.
Unparalleled stability reduces calibration
frequency
Competitor devices can drift out of specification in
just a few months and require re-calibration,
consuming your time and money and risking
regulatory non-compliance. The 4500 provides a
better stability so that you can confidently extend
calibration frequencies to reduce maintenance costs.
4-20mA/HART output and AMS Suite
compatibility ensures easier configurations,
calibrations and operation
Using AMS Suite software can lower maintenance
costs, improve device performance and enable
easier configuration and setup. Combining AMS
Suite with the 4500 can also provide you with
advanced functionality such as predictive diagnostics
and audit trail information to make FDA compliance
simpler and paper free.
PERFORMANCE SPECIFICATIONS
For zero-based spans, reference conditions, Neobee M-20 oil fill,
SST materials, 11/2 in. tri-clamp process connections, digital trim
values set to equal range points.
Conformance to specification (±3 Sigma)
Technology leadership, advanced manufacturing techniques and
statistical process control ensure specification conformance to at
least ±3 sigma.
Reference Accuracy
Includes the effects of terminal based linearity, hysteresis, and
repeatability.
±0.15% of calibrated span (CS) from 1:1 to 15:1 rangedown
±0.01 % of calibrated span from 15:1 to 50:1 rangedown

Service
Liquid, gas, vapor, and steam applications
420 mA (output code A)
Zero and Span Adjustment
Zero and span values can be set anywhere within the range.
Span must be greater than or equal to the minimum span.
Output
Digital process variable superimposed on 420 mA signal,
available to any host that conforms to the HART protocol.
Power Supply
External power supply required. Standard transmitter
(420 mA) operates on 11.25 to 42.4 V dc with no load.
Load Limitations
Maximum loop resistance is determined by the voltage level of
the external power supply.
Burst Pressure Limits
Range 1: 300 psi (20.68 bar)
Range 2: 450 psi (31.02 bar)
Temperature Limits
Ambient
32 to 140 °F (0 to 60 °C)
Storage
22 to 185 °F (30 to 85 °C)
Process Temperature Limits
32 to 400°F (0 to 204°C)
Horizontal Mount
For process temperatures above 293°F (145°C), derate
ambient temperature by 7°F (4°C) for every 18°F (10°C)
increase in process temperature.
Top Mount
For process temperatures above 266°F (130°C), derate
ambient temperature by 9°F (5°C) for every 18°F (10°C)
increase in process temperature.
Turn-On Time
Performance within specifications less than 2.0 seconds after
power is applied to the transmitter
Damping
Analog output response to a step input change is user-selectable
from 0 to 60 seconds for one time constant. This software damping
is in addition to sensor module response time.
Failure Mode Alarm
HART 4-20mA (output code A)
If self-diagnostics detect a gross transmitter failure, the analog
signal will be driven offscale to alert the user. Rosemount
standard and custom alarm levels are available.
High or low alarm signal is software-selectable.
