DRUCK DPI 705E Digital Pressure Indicator
Product Overview
Introduction
The Druck DPI 705E / DPI 705E-IS pressure indicator uses a silicon transducer to produce a pressure reading in pressure units. These user instructions include the operations for all DPI 705E / DPI 705E-IS Pressure Indicators, safety instructions, and the requirements for intrinsically safe instruments. The DPI 705E / DPI 705E-IS is equipped with ISO 228 G1/8 female pressure connectors up to 350 bar (5000 psi, 35 MPa). Above 350 bar (5000 psi, 35 MPa), autoclave male pressure connectors are supplied. For NPT pressure connectors, use Druck adaptor IO-ADAPT-9/16AUTOC. For the full specification and user manual, refer to the Druck website:
WARNING: Do not use the non-intrinsically safe DPI 705E in locations where explosive gas, vapor or dust are present. There is a risk of an explosion. Some liquid and gas mixtures are dangerous. This includes mixtures that occur because of contamination. Make sure that the DPI 705E / DPI 705E-IS is safe to use with the necessary media. It is dangerous to ignore the specified limits (refer to data sheet) for the DPI 705E / DPI 705E-IS or to use the DPI 705E / DPI 705E-IS when it is not in its normal condition. Use the applicable protection and obey all safety precautions. To prevent a dangerous release of pressure, isolate and bleed the system before disconnecting a pressure connection. A dangerous release of pressure can cause injury. Do not apply pressure greater than the maximum safe working pressure. Do not apply pressure greater than 1.1 bar (15.95 psi, 110 kPa) absolute to the REF pressure port of differential pressure indicators. To prevent an explosion or fire, use only the Druck specified battery. Remove batteries from the pressure indicator immediately when discharged and before storage.
Safety
The DPI 705E / DPI 705E-IS has been designed to be safe when operated using
the procedures detailed in this manual. Do not use this equipment for any
other purpose than that stated, the protection provided by the equipment may
be impaired. The product contains a Lithium coin cell for data backup. This
cell is not user replaceable. Before installing and using the DPI 705E / DPI
705E-IS, read and understand all the related data. This includes all local
safety procedures and installation standards, and this document.

Installation
WARNING: Do not use tools on the pressure indicator that might cause
incendive sparks – this can cause an explosion. Only fluids that are
compatible with Stainless Steel and Hastelloy shall be used with the pressure
sensors. This is to ensure the integrity of the pressure sensor and avoid
fluid leakage.
CAUTION: Do not use the body of the DPI 705E / DPI 705E-IS to tighten the
pressure connection, this can cause damage. Use the flat faces on the pressure
connector to hold the body and tighten the pressure union. Do not exceed the
maximum working pressure of the instrument.
The pressure port on the DPI 705E / DPI 705E-IS and the metal body of the
remote sensor PM 700E / PM 700E-IS are connected directly to the circuit earth
of the DPI 705E / DPI 705E-IS. The DPI 705E / DPI 705E-IS is battery-powered
only and not intended to be connected to any external electrical connection.
These instructions detail the requirements for using the DPI 705E-IS Intrinsically Safe Pressure Indicator in a hazardous area. Read the whole publication before starting.
- Installation should be carried out by qualified plant installation technicians in compliance with all local safety procedures and installation standards. For example IEC/EN 60079-14, US National Electrical Code NFPA 70 or Canadian Electrical Code (CEC).
- Provide additional protection for indicators that may be damaged in service.
The DPI 705E / 705E-IS is fitted with a G1/8 connector. Refer to Figure A2 and
key below for connector detail and the correct fitting method:
Note: Maximum torque which should be applied is up to ISO 228/1, G1/8: 25
Nm (221 in lb).
- DPI 705E / DPI 705E-IS pressure connector.
- Bonded Seal, e.g. Dowty 400-003-4490-41 or equivalent.
- ISO 228/1 G1/8 pressure connector.
- NPT pressure connector.
- NPT female to G1/8 male adapter IO-ADAPT-1/4NPT or IO-ADAPT-1/8NPT.
The pressure range is marked on the product label; refer to item 1 Figure A1.
Batteries
CAUTION: Do not mix cell types. Do not mix old and new cells. Remove cells from the unit when placed in storage for an extended period of time. If a cell has leaked return the unit to an approved Druck Service Centre.
For DPI 705E-IS use only 4 x AA LR6 primary cells from the following list:
- GP 15A Alkaline
- Energizer Ultimate Lithium
Replacing the Batteries
This symbol indicates that the batteries are low, replacing the observing polarity shown on the case.
The non intrinsically safe (Blue, DPI 705E) unit can operate from alkaline, Ni-Cd, Ni-MH or lithium batteries. In US and Canada:
- Ni-Cd and Ni-MH batteries must comply with UL 2054, IEC 62133, IEC 61951-1 or IEC 61951-2 and shall be acceptable when connected in series.
- Lithium batteries must comply with UL 1642 and IEC 62133-2 and shall be acceptable when connected in series.
- When replacing a battery, all 4 batteries should be replaced with fresh/new batteries at the same time.
The intrinsically safe (Yellow, DPI 705E-IS) unit shall only use the batteries
specified in section “Batteries” on page 2. The instrument requires 4 x AA/LR6
batteries. Fit as shown in Figure A3. Use a small positive screwdriver to
loosen the captive screws in the battery compartment cover. The battery
orientation is shown on the back of the instrument as shown in Figure A3.
Accessory Socket
WARNING: No connection is permitted to devices with independent power
sources.
The equipment has a single electrical port for connecting a remote sensor PM 700E / PM 700E-IS. Refer to item 1 in Figure A4. For the accessory socket entity parameters refer to Table A5.
Specific Conditions of Use
- Use only Energizer Ultimate Lithium Cell Type L91 (AA type batteries) or GP 15A Alkaline AA with the equipment.
- There shall be no mixing of battery types inserted into the equipment. All batteries inserted must be of the same electrochemical system, cell design, rated capacity and made by the same manufacturer.
- Only fresh batteries are to be used with the equipment.
- Do not recharge the batteries.
- Ensure the correct polarity of the batteries when inserted into the equipment.
- Batteries are only to be installed/replaced by authorized personnel referring to the user manual.
- Hazardous Area (yellow) products may be used with flammable liquids. Standard commercial (blue) product is not to be used with flammable liquids.
- This assessment covers the basic safety of the equipment only (hazardous and non-hazardous locations). It does not cover reliable function, performance or other properties of the equipment not related to safety.
- In order to maintain pressure integrity of the sensors (subsequently avoiding leakage) the installation and/or end-application of this equipment must only allow use of pressure medium fluids that are compatible with the sensor materials which are Stainless Steel and Hastelloy.

Quick Start
Time Out
If a key is not pressed within 10 minutes, the instrument times out and
switches off.
Leak Test
To perform a leak test, press the Leak key three times. The timer symbol
shows on the display with a leak test duration of 60 seconds. Press the
Tare key to increase the duration to 120 or 300 seconds. To start the leak
test, press the key again. The instrument counts down to zero, then displays
the leak rate. Press the key at any time during the leak test to quit and
return to normal measurement.
Zero
A zero should be performed on gauge and differential instruments before
measuring pressure. To perform a zero, open all pressure ports to atmospheric
pressure. Press the Tare keys together. The display briefly shows and the
instrument calculates a new zero.
