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 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.

700E

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.

External Sensors

The DPI 705E supports two types of external sensor, both of which connect via a cable into the righthand side of the unit.

External sensor connector

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 “ from the external sensor. To show a reading from the internal pressure sensor the external sensor must be unplugged.

” (External Sensor) to show that the reading is

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.

iv | 137M7122 DPI 705E / DPI 705E IS User Manual–English

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.

4. The number of days remaining to the next calibration due date are then briefly displayed.

137M7122 DPI 705E / DPI 705E IS User Manual–English | 1

5. The sensor reading screen is then displayed as below. This is the default state or main screen of the instrument.

1.2 Pressure Measurement

The DPI 705E can be used to measure pressure from an external pressure source - it does not generate pressure itself.

To measure pressure:

1. Connect an external pressure source to be measured via the P1 pressure port at the top of the instrument.

2. The instrument will display the measured pressure using the internal sensor as shown below.

3. To measure pressure via an external sensor, connect an external sensor via the port on the right side of the instrument.

4. The instrument will then measure pressure using the external sensor as shown below.

Note: The sensor type (absolute or gauge) will be shown on the display as “ ” or “ ”. Differential sensors are indicated as gauge.

1.3 Temperature Measurement

The DPI 705E can be used to measure temperature using the RTD-INTERFACE. To measure temperature:

1. Connect the RTD-INTERFACE via the port on the right of the instrument, and connect an RTD-PROBE or PT100 to the RTD-INTERFACE.

2. The instrument will measure temperature in Degrees Celsius by default as shown below.

3. To change the temperature unit, press the key. The temperature reading is now shown in Degrees Fahrenheit.

4. To change the measurement unit, press the key again. The reading is now shown in Ohms.

1.4 ZERO

CAUTION Zero is a function that causes a non-reversible adjustment of the

zero reading and effectively adjusts the calibration of the sensor. Do not confuse zero with tare - please read both sections if uncertain.

A zero should be performed on a Gauge or Differential pressure instrument before measuring pressure. The zero function is not available on absolute pressure sensors (because absolute vacuum would have to be applied to them to make it valid) and is not available on RTD-Interface.

To perform a zero:

1. Open all pressure ports to atmospheric pressure.

2. Press the and keys together.

137M7122 DPI 705E / DPI 705E IS User Manual–English | 3

3. The display will briefly show “ ” (Zero) indicating that the zero function has been successful.
