1 Features

Figure 1-1: Rosemount™ 550DW with Sensor Installed

Robust sensor adapter

• Sensor window compatible with standard dissolved oxygen sensors without reducing

measurement performance.

• Adapts sensors designed for stainless steel bioreactors into single-use bags.

• Membrane allows for up to 10 psi (68.9 kPa) pressure without a sensor supporting.

• Compatible with 4.7 in. (120 mm) sensor with a PG13.5 process connector.

• All wetted materials are USP Class VI, ADI-free, and chosen for minimal extractables.

Ease of installation

• Reuse dissolved oxygen sensor across multiple batches without autoclaving, as it does

not contact process solutions.

• Adapter arrives installed and gamma-irradiated with the single-use bioreactor bag.

3 Install

To install the dissolved oxygen sensor into the Rosemount™ 550DW adapter:

Prerequisites

Note

For automatic temperature compensation on the Rosemount 56 transmitter, please select
the "Single-use Biopharm" option on the transmitter during sensor startup. Otherwise,
refer to Manual temperature compensation for manual temperature compensation.

Procedure

1. Clip the small zip tie connecting the PG13.5 adapter to the body of the adapter.

2. Press the blue thumb press to the unlocked position.

3. Remove the PG13.5 connector from the body of the adapter.

4. Push calibrated sensor through the PG13.5 connector and screw the sensor to a

torque of 40 in./lb. (4.5 N*m). Follow the instructions in the sensor manual for
calibration and wiring procedures.

5. Slowly push the sensor and adapter into the body of the adapter.

The body of the adapter is designed to allow air to escape as the sensor is installed.

6. Lock the sensor into place by pressing the thumb press to the locked position.

5 Troubleshoot

5.1 Label information too small

The serial number, Cal pH, or slope are too small to read.

Recommended action

Scan the two-dimensional bar code on the sensor label to retrieve information.

5.2 Manual temperature compensation

The following procedure was completed on a Rosemount™ 1056 Transmitter with a
dissolved oxygen sensor in position 1. The purpose of this compensation is to ensure the
transmitter is using the correct temperature due to heat transfer across the adapter.

Procedure

1. From the main screen, press Menu.

2. Select "Program" on the screen and press Enter.

3. Select "Temperature" on the screen and press Enter.

4. Select "S1 Temp Comp".

5. Select "Manual".

6. Input the process temperature from the temperature control unit and press Enter.

Note

The displayed temperature on the transmitter will still be the live reading from the
dissolved oxygen, but the software will now use manual input temperature for DO
concentration compensation.
