The DPG1000L/DPG1100L series is a 2-wire pressure transmitter with a digital display. It is powered by the 4-20 mA current
loop and produces an analog output signal. The output is filtered
to improve noise immunity. It may also be connected to a low
voltage DC supply for use as a pressure indicator.
Ranges up to 1999 have a 3.5 digit display and true analog
output. Ranges 2000 and above are microprocessor based
and use a 4 digit display with an alphanumeric lower display.
The output is a 12,000 count analog 4-20 mA signal updated
approx. 16 times per second.
Models are designed for continuous operation. Warm-up time is
negligible. The display will show the system pressure/vacuum
and the loop current will be proportional to the system pressure/
vacuum; 4 mA = Zero or low end, 20 mA = Span, full-scale or
high end.
The TEST button, when depressed, switches the display and
output loop to a preset level determined by the setting of a Test
potentiometer. This is useful for testing the 4-20 mA output
signal without having to alter system pressure.

Installation Precautions
4 Read these instructions before using the gauge. Configuration
may be easier before installation. Contact the factory for
assistance.
4 These products do not contain user-serviceable parts.
Contact us for repairs, service, or refurbishment.
4 Gauges must be operated within specified ambient
temperature ranges.
4 Outdoor or wash down applications require a NEMA 4X
gauge or installation in a NEMA 4X housing.
4 Use a pressure or vacuum range appropriate for the
application.
4 Use fittings appropriate for the pressure range of the gauge.
All Models—Electrical Connections
Connect the 2-wire cable to an 8-32 VDC power source. The
gauge will not operate with incorrect polarity. See the wiring
examples below for connecting to a 4-20 mA current loop.

4 Due to the hardness of 316 stainless steel, it is recommended
that a thread sealant be used to ensure leak-free operation.
4 For contaminated media use an appropriate screen or filter
to keep debris out of gauge port.
4 Remove system pressures before removing or installing
gauge.
4 Install or remove gauge using a wrench on the hex fitting
only. Do not attempt to turn gauge by forcing the housing.
4 Good design practice dictates that positive displacement
liquid pumps include protection devices to prevent sensor
damage from pressure spikes, acceleration head, and
vacuum extremes.
Select a loop power supply voltage and total loop resistance
so that when the loop current is 20 mA, the gauge will have at
least 8 VDC at its terminals. For correct operation, the gauge
terminal voltage must not fall below 8 VDC. Too large a loop
resistance will cause the gauge output to “limit” or saturate
before reaching its full 20 mA output.
The minimum loop supply voltage may be calculated from the
formula:
Vmin = 8V + (20mA x Total loop resistance)
Avoid permanent sensor damage! Do not apply vacuum to
non-vacuum gauges or hydraulic vacuum to any gauges.
Avoid permanent sensor damage! NEVER insert objects into
gauge port or blow out with compressed air.
Gauges are not for oxygen service. Accidental rupture of
sensor diaphragm may cause silicone oil inside sensor to
react with oxygen.
NEVER connect the gauge wires directly to 115 VAC or
permanent damage will result.
WARNING: This product can expose you to chemicals including
lead, nickel and chromium, which are known to the State of
California to cause cancer or birth defects or other reproductive
harm. For more information go to www.P65Warnings.ca.gov
If the terminal voltage of the gauge falls below about 7.8 VDC,
erratic operation may occur. This is an indication that the
loop supply/resistance may not allow adequate headroom for
reliable operation. This should never occur in normal use. If it
does, examine the loop supply/resistance.
If the 4-20 mA analog output is not required, the transmitter
can be simply connected to any 8-32 VDC power supply.

Operation
Models are designed for continuous operation. Warm-up time
is negligible.
When power is first applied, the gauge will power up and be
ready for use. The display will show the system pressure or
vacuum, and the loop current will be proportional to the system
pressure/vacuum.
Do not apply vacuum unless model range is designated as
vacuum, bipolar, or absolute reference. See specifications for
sensors that can be used for vacuum service. Vacuum will
damage 3 psig, 5 psig, 30 psig, 60, psig, 300 psig, and 500
psig sensors.

Calibration Preparation
Gauges are calibrated at the factory using equipment traceable
to NIST. There is no need to calibrate the gauge before putting
it into service.
Calibration should only be performed by qualified individuals
using appropriate calibration standards and procedures. Gauges
can be returned to factory for certified calibration and repairs.
NIST traceability is available.
Calibration intervals depend on your quality control program
requirements and as-found data. Many customers calibrate
their equipment annually.
The calibration equipment should be at least four times more
accurate than the gauge being calibrated. The calibration
system must be able to generate and measure pressure and/or
vacuum over the full range of the gauge.
A vacuum pump able to produce a vacuum of 100 microns (0.1
torr or 100 millitorr) or lower is required for vacuum and absolute
gauges.
Warning: application of vacuum to non-vacuum models may
result in irreparable damage to the sensor.
Use a stable DC power supply and an accurate mA meter for
calibration of loop powered transmitters.
Allow the gauge to equalize to normal room temperature (about
20 minutes minimum) before calibration.
20 mA = Full-scale pressure of the sensor used
Note that absolute gauges read atmospheric pressure with the
gauge port open to atmosphere. Atmospheric pressure and
thus the gauge reading, will vary continuously. For example a
15 psia sensor may read 14 psia depending on local barometric
pressure and the effects of altitude.
Calibration
1. See rear label of gauge for pressure range.
2. Remove the covers on the Zero and Span controls on the
front of the gauge.
3. Loop-powered gauges must be connected to 8-32 VDC
during the calibration procedure. The supply voltage has
negligible effects on the gauge calibration as long as it is
within the stated voltage ranges.
4. Internal Zero and Span potentiometers adjust the
agreement between the display and the analog output.
These normally do not need to be adjusted. If the output
does need adjustment, remove the rear cover to access the
potentiometers. See image below.
5. Zero for gauge reference pressure or vacuum gauges:
With the gauge port open to atmosphere, adjust the Zero
potentiometer for a display indication of zero. Output should
be 4.0 milliamps.
Zero for absolute reference gauges: Apply full vacuum to the
gauge. Adjust the Zero potentiometer for a display indication
of zero. Output should be 4.0 milliamps.
6. Span for gauge reference pressure gauges and absolute
reference gauges: Apply full-scale pressure and adjust the
Span potentiometer for a display indication equal to fullscale pressure. Output should be 20.0 milliamps.
Span for gauge reference vacuum gauges: Apply full vacuum
to the gauge. Adjust the Span potentiometer for a display
indication equal to full-scale vacuum. Output should be 20.0
milliamps.
7. Verify pressure indications at 0%, 25%, 50%, 75%, and
100% of full scale and repeat calibration as needed to
achieve best accuracy over desired operating range.
8. Replace the potentiometer covers, rear cover and screws,
taking care not to pinch the wires between the case and the
rear cover.

Power Up & Operation
Models are designed for continuous operation. Warm-up time
is negligible.
When power is first applied, the gauge proceeds through a
startup sequence as follows.
1. All active display segments are turned on for approximately
1 second.
2. The full scale pressure is indicated for approximately 1
second, while the engineering units are displayed for 1/2
second on the character segments and then FS (Full Scale)
is displayed for 1/2 second on the character segments.
3. All active display segments are again turned on for
approximately 1 second.
After initialization, the display and the loop current will
correspond to the applied pressure. The output is linearly
proportional to the pressure.
4 mA = Zero or gauge port open to atmosphere
20 mA = Full-scale pressure or vacuum, depending on range
Low Loop Voltage or Out-of-Range Indications
At power-up, if the available voltage is not sufficient, only
the low power segment will be displayed indicating that loop
resistance is too high or the loop power supply voltage is too
low.
After successful power-up, if the loop voltage falls below
the minimum required for reliable operation, the display will
continue to indicate pressure with the low power segment
blinking at a slow rate.
Pressure out-of-range indication
112.5% out-of-range display: 1 – – – or 1 –.–.–.– depending
on model.
Test Function
When the front-panel TEST button is held depressed, the display
and loop current are switched, independent of the system
pressure, to a test level determined by the test setting.
This test mode will allow setup and testing of the current loop
by switching to this test level whenever desired without having
to alter the system pressure.
1. To set the test output level, press and hold the front-panel
TEST button.
2. Press the s or t buttons to adjust the test output to the
desired pressure setting.
3. Release the TEST button. The setting is stored in non-volatile
memory.
When the TEST button is held depressed, the display and loop
current are switched, independent of the actual pressure,
to a level determined by the test setting. When the button is
released, normal operation is resumed.
Calibration Preparation
Gauges are calibrated at the factory using equipment traceable
to NIST. There is no need to calibrate the gauge before putting
it into service.
Calibration intervals depend on your quality control program
requirements and as-found data. Many customers calibrate
their equipment annually.
Calibration should only be performed by qualified individuals
using appropriate calibration standards and procedures. Gauges
may be returned to Omega for NIST traceabile calibration.
The calibration equipment should be at least four times more
accurate than the gauge being calibrated. The calibration
system must be able to generate and measure pressure/
vacuum over the full range of the gauge.
A vacuum pump able to produce a vacuum of 100 microns
(0.1 torr or 100 millitorr) or lower is required for vacuum and
absolute gauges. Warning: application of vacuum to nonvacuum models will result in damage to the sensor.
Connect to a stable 8-32 VDC power supply during the
calibration procedure. The supply voltage has negligible effects
on the gauge calibration as long as it is within the stated voltage
ranges. Over voltage may result in damage.
Use an accurate mA meter for calibration of the 4-20 mA output.
Allow approximately 20 minutes for the gauge to equalize to
normal room temperature before calibration.
