The OMEGA® DP41 Series of digital
panel meter/controllers has set the
world standard for accuracy and
quality in industrial instrumentation.
These meters can measure a broad
spectrum of DC voltage and current
ranges as well as inputs from
9 thermocouple types and from
most RTDs, pressure transducers,
load cells, strain gages, and
potentiometers. Models include the
DP41-W, a legal-for-trade, NTEPcertified strain meter with enhanced
features, and the DP41-U, which
covers all the input types.
The DP41 displays feature 14-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 14-segment
LED characters on
the DP41, which,
in turn, simplifies
operating and
programming.

Standard features include 6-digit
display; 5 front-panel pushbutton
keys; 4 open-collector outputs; and
alarm/control, BCD, and analog
outputs. Configurable analog output
ranges are 0 to 20 mA, 4 to 20 mA,
0 to 5 Vdc, and 0 to 10 Vdc.
On-board excitation allows these
meters to power virtually any sensor
or transmitter, and 4 setpoints give
the user numerous control/alarm
possibilities. Setpoint configurations
include active above or below;
latching or non-latching; and high
deviation, low deviation, or band
deviation.
With the RS232/485 serial
communications option, the user
can set the display parameters
and read the current, max, and
min values remotely. The DP40-R
board option provides dual 7 A
mechanical relays, activated by the
selected setpoint.
Red LED display standard. Also
available with green LED at no charge.

The DP41 thermocouple meter offers very high accuracy ensured by an
advanced (patent applied for) thermocouple linearizing s
ystem. Accuracy
for most thermocouple types is 0.2°C (3.6ºF). The meter is front-panel
programmable for any of 9 thermocouple types. The DP41 RTD input meter
is programmable for any 6 to 6000 Ω DIN or NIST platinum RTD. It provides
a precision ultra-low constant current excitation to minimize self-heating
errors and maximize stability.
