Introduction
This user manual covers the DPI 705E / DPI 705E-IS measurement instrument and its associated
remote probes, PM 700E / PM 700E-IS for pressure measurement and RTD-INTERFACE /
RTD-INTERFACE-IS for temperature measurement.
Unless specifically stated in a section all references to DPI 705E cover both DPI 705E (non-
Intrinsically Safe) and DPI 705E-IS (Intrinsically Safe). This also applies to PM 700E, PM 700E-IS and
RTD-INTERFACE, RTD-INTERFACE-IS.
DPI 705E Series Digital Pressure Indicator
The Druck DPI 705E pressure indicator uses a silicon transducer to produce a pressure reading in
various pressure measurement units. These user instructions include the operations for all DPI 705E
Pressure Indicators, safety instructions and the requirements for intrinsically safe instruments.
The PM 700E provide a remote pressure sensor function for the DPI 705E to allow more convenient
connection when direct connection of the handheld instrument would be inconvenient. The PM 700E
is a “plug and play” device holding its own calibration data, so it can be used to have multiple
pressure range sensors available for immediate use with a single DPI 705E instrument.
The RTD-INTERFACE is a remote interface for use with the DPI 705E or the DPI 620G to allow
connection of a PT 100 RTD probe to the instrument for the purpose of measuring temperature.
For all accuracy specifications etc refer to the relevant product datasheet, available for download
from Druck.com/essential.

Commercial and Intrinsically Safe Product versions
The DPI 705E is available as either non-Intrinsically Safe (blue in color) or Intrinsically safe (yellow in
color) versions, with case coloring used as well as labeling to indicate the version.
The remote pressure sensor PM 700E and the remote RTD interface RTD-INTERFACE are available as
either non-Intrinsically Safe or Intrinsically safe versions. The outer metal body of the product is
marked with its part number and relevant approvals.
Safety
For all safety information on both commercial and Intrinsically Safe versions refer to the Quick Start
and Safety Manual provided with the unit and also available for download on Druck.com/essential.
Pressure Connectors and Adaptors
The DPI 705E and PM 700E are fitted with female G1/8 pressure connectors for the main pressure
port P1 for ranges 25 mbar - 200 bar(0.36 psi - 2900 psi). For pressures 350 bar-1400 bar(5000 psi -
20000 psi) Autoclave male pressure connectors are used. The main pressure port P1 is shown on the
left in the picture below.
For differential units/sensors fitted with a reference port a Legris adaptor is fitted giving a 4mm
tubing fitting. This is shown as the Ref port on the right in the image below.
Various adaptors are available (either as accessories or configured when ordering) for the G1/8
connection to convert to other standards. Please see datasheet for full details.

Batteries
For compatible battery types refer to Quick Start and Safety Manual provided with the unit and also
available for download on Druck.com/essential
The instrument requires 4 xAA/LR6 batteries, fitted as per below image. Use a small Posidrive
screwdriver to loosen the screws in the battery compartment cover and fit as per the battery
orientation shown on the back of the instrument as illustrated below:
1 DPI 705E or PM 700E G1/8 port
2 Bonded seal 110N3018
3 ISO 228/1 G1/8
4 NPT thread pressure connector IO-ADAPT-1/4NPT or IO-ADAPT-1/8NPT
5 NPT female to G1/8 male adapter part number IO-ADAPT-1/4NPT

External Sensors
The DPI 705E supports two types of external sensor, both of which connect via a cable into the right-
hand side of the unit.
The sensor must be connected via supplied connection cable (it will not engage correctly if directly
plugged in). The connectors push in (with pip features aligned) then the outer body rotates clockwise
to lock the connector in position. Multiple cables may be used in series (i.e. as extenders). Up to a
maximum of 10 in series if very long cabled connections are needed.
When an external sensor is connected it is automatically detected and has precedence over the
internal sensors. The display shows “ ” (External Sensor) to show that the reading is
from the external sensor. To show a reading from the internal pressure sensor the external sensor
must be unplugged.
The external sensor may be either:
• A pressure sensor PM 700E ranging from 25 mbar to 1,400 bar (0.36 psi to 20,000 psi)
full-scale.
• A temperature sensor adaptor RTD-INTERFACE which supports a 4-wire PT100 probe.
If a PM 700E pressure sensor is plugged in then the pressure Full-scale will be displayed (only at first
plug-in), followed by the calibration due date in days. Normal pressure measurement display will
then start.
If an RTD-INTERFACE temperature sensor is plugged in then temperature/resistance full-scale will
be displayed (only at first plug-in), followed by the calibration due date in days. Normal resistance or
temperature measurement display will then start.
RTD Wiring
The DPI 705E M12 connector is to be connected to an external RTD probe as shown below.

The RTD-INTERFACE is optionally supplied with a field-rewirable M12 connector for customers to
connect their own wire-ended RTD's into. This is accessory part number IO-RTD-M12CON. The pin
numbering is printed on the rear of the connector body and is reproduced below for clarity.
