The DPI 150 precision pressure indicator is a single
range instrument designed to provide high accuracy
and excellent long term measurement stability at an
economical price. The instrument uses the latest
techniques in pressure measurement and
manufacturing technology to combine reliability,
ruggedness and accuracy with minimal cost.

Features High Performance, Low Cost

DPI 150 is a Druck product.
Druck has joined other
GE high-technology sensing
businesses under a new
name—GE Sensing.

Versatility

The DPI 150 offers powerful versatility in a small
package and provides a range of dedicated pressure
functions.

The instrument has been designed to function as a
local indicator, while the digital communications
provide connectivity to larger systems required to log
or monitor pressure precisely.

Pressure Indication

The primary function of the instrument is accurate
pressure measurement. The pressure value can be
displayed in one of 24 internationally recognized
standard pressure units:

Pa, hPa, kPa, MPa, mbar, bar, kg/cm2, kg/m2, mmHg,
cmHg, mHg, mmH2O, cmH2O, mH2O, torr, atm, psi, lb/ft2,
inHg, inH2O 39°F and 68°F (4°C and 20°C),
ftH2O 39°F and 68°F (4°C and 20°C), inH2O 60°F (15°C).

Two user-configurable pressure scales are included
and may be programmed as a ratio to Pascals.

Measurement precision is maintained by regular
zeroing of the sensor, which is simply achieved via a
front panel key press.

The process functions for tare, hold (front panel key),
% FS, maximum/minimum capture and filter are also
available in this mode.

Pressure Leak Testing

A dedicated leak test mode allows the user to set a test
time up to 999 seconds. The instrument will calculate
the leak rate over this period in current pressure units
and display the results.

Airspeed

This mode converts the differential pressure from the
input into Knots, mph or km/hr.

The process functions for tare, hold (front panel key)
and filter are also available in this mode.

Airspeed Leak Testing

Similar to the pressure leak test, but will calculate the
leak rate in selected airspeed units and display the
results.

Instrument Status

The calibration and maintenance history of the DPI 150,
along with its configuration, are stored within the
instrument and can be viewed via status screens in the
instrument set-up menu.

Analog Output (Optional)

This option can be programmed via the set-up menu
screen to output a signal proportional to the instrument
range selected. This allows the instrument to interface
with PC or PLC I/O cards, remote displays, chart
recorders or other data logging equipment.

Barometric Reference (Optional)

The DPI 150 is a gauge pressure indicator; in order to
measure absolute pressures an optional barometric
reference is required. The indicator will add an
atmospheric reading from the reference port (located
on the back panel) to the gauge pressure at the
positive input to provide an accurate absolute pressure
reading on the display.

External IDOS Sensor

The DPI 150 rear panel has a female five-pin socket for
attaching the new IDOS external universal pressure
module (UPM or UPMP).

The DPI 150 can be ordered without an internal
pressure range if only external measurement is
required. In this case no range should be specified for
the DPI 150 and the appropriate IDOS UPM (standard
version) or IDOS UPMP (high precision version) sensors
should be ordered. See the separate IDOS datasheet for
information.

A single DPI 150 can display one pressure reading at a
time, but can switch between internal and external
sensors. Absolute ranges are created by adding the
barometer and gauge readings.

The IDOS sensors are supplied with their own
calibration data, making the external IDOS fully
interchangeable between IDOS compatible products
such as the DPI 150 and the DPI 800 portable
calibrator.
