OMEGA goes
BEYOND with the all new DP41-B. The OMEGA set the
world standard for accuracy, performance and quality in digital
panel meters. The all new DP41-B raises the bar even higher
with accuracy of up to ±0.005%
of reading, and up to 166 readings per second.
The versatile OMEGA DP41-B handles a broad spectrum of
dc voltage and current ranges, nine thermocouple types, multiple
RTD's, and signals from strain gauge transducers such as load
cells and pressure transducers, as well as potentiometric inputs.
It also features ten point linearization of input signals, progammable
by the user for custom applications.
Built-in excitation to power virtually any sensor or transmitter,
and four isolated open collector outputs for control or alarms
are standard. The big, bright, 6 digit patented LED display can
be programmed to change color between Red, Amber, and Green at
any set point. The digits are 58% bigger than the typical display.
Output options include: Isolated programmable analog voltage or
current and four relays.
With the Serial Communications option, the user can select from
a push-button menu between RS-232, RS-485, and either a straightforward
ASCII protocol or MODBUS. With OMEGA’S award-winning Ethernet/Internet
option, the new DP41-B connects directly to an Ethernet
network and transmits data in standard TCP/IP protocol. It is
possible to monitor and control a process through a web browser
from anywhere on the Internet.
Embedded
Internet and Serial Communications
Featuring optional "Embedded Internet" (specify EI option) the
DP41-B
connects directly to an Ethernet network and transmit data in
standard TCP/IP packets, or even serve Web pages over a LAN or
the Internet. The DP41-B is also available with serial communications.
With the C24 option, the user can select from the push-button
menu between RS-232, RS-422, and RS-485, with straightforward
ASCII commands or MODBUS.
Programmable
Color Display
The
OMEGA DP41-B has totally programmable color displays.
The display can be programmed to change color at any set point
or alarm point.
U.S. Patent #6,243,021 |
Change Color at any Setpoint
|
For example, the instrument can be programmed to display the
process value in GREEN
during warm-up, switching to AMBER
to signal the normal operating range, and in RED
to signal an alarm condition. The changes in color are quickly
seen from a distance, and machine operators can intuitively
react to changing conditions. The colors can be programmed to
change back when the value drops back below the alarm point
or to "latch" on until being reset by the operator.
The instrument can also be programmed to display only one unchanging
color: GREEN, AMBER,
or RED. This is a useful
way to let an operator identify, at a glance, process values
in three separate locations, or to display three different measurements
such as Temperature, Pressure, and Flow. DP41-B
LED displays are considerably bigger, brighter and therefore
more visible than displays for conventional instruments with
the same DIN size.
QUALITY
and TECHNOLOGY
Designed and manufactured in the USA, the innovative OMEGA®
DP41-B meters feature an extended five (5) YEAR warranty
at no extra charge. The DP41-B
packs a wealth of power and features using COB (chip-on-board)
and SMT (surface mount technology) assembly techniques and automation.
Every DP41-B
instrument is thoroughly calibrated and tested at several stages
throughout production. The DP41-B
offers the highest accuracy for industrial instrumentation at
0.005% of reading. The analog-to-digital conversion utilizes
patented algorithms and smart filtering.
Universal
Inputs
The innovative DP41-B
offers the broadest selection of signal inputs available on
one industrial instrument. The choices are easily selected from
the menu with four front panel pushbuttons, or by serial or
ethernet communications.
9
Thermocouple Types
The DP41-B
handles NINE (9) thermocouple types: K, J, T, E, R, S, B, N,
and J DIN. The patented thermocouple linearization algorithms
employed in the DP41-B
produce the highest standard of accuracy.
Most
Accurate RTD Measurements
The DP41-B
works with the widest selection of RTD's and produces the most
accurate RTD measurements. Handles 100 ohm Pt both 0.00385 and
0.00392 curves. Any 6 to 6000 ohm NIST or DIN Pt and any linear
RTD (10 ohm Cu, etc.). A choice of 2-, 3- and 4-wire RTD connections
ensures the absolute highest degree of accuracy.
Process Voltage and Current
The OMEGA®
DP41-B
measures process voltage: 0-100 mV, 0-1 V, 0-10 V, 0-100 V (unipolar),
±50
mV, ±500
mV, ±5
V, ±50
V (bipolar) ranges, and process current: 0-20 mA
or 4-20 mA.
Strain
Gauge
The DP41-B measure inputs from Load Cells, Pressure Transducers,
and most any strain gauge sensor. Input can be linearized over
10 pts on ranges.
0-100 mV, 0-1 V, 0-10 V, 0-100 V (unipolar), ±50
mV, ±500
mV, ±5
V, ±50
V (bipolar), in
addition to 0-20mA. Excitation for transducers of 10 Volt and
24 Volt is standard.
Analog
Output
The optional analog output can be programmed within a
range of 0-10 Vdc or 0-20 mA. It is selectable as a calibrated
retransmission of the process value.
Built-in
Excitation Standard
The DP41-B
comes standard with built-in excitation. You can capture
and display both peak and valley levels of your input
signals, an important feature for such applications as
destructive and pressure testing. Five different kinds
of excitation are available for sensors such as transmitters
(24 Vdc @ 25 mA), strain gages (1.5 to 10 Vdc @ up to
60 mA max.), slide-wire potentiometers (1.25 Vdc @ 30
mA). |
 |
| The
DP41-B features plug/removable connectors and a sturdy
panel mounting sleeve with adjustable thumb
nuts
for easy secure installation |
|
The
DP41-B
displays feature unique 9-segment LED characters, which greatly
improves alphanumeric representations. The 7-segment LED characters
found on most instruments are adequate for presenting numbers,
but not letters. Words are easier to read with the unique 9-segment
LED characters on the DP41-B,
which makes operating and programming simpler and easier.
