D435 (25mm Braun) Dissolved Oxygen Sensor is designed specifically for use with B. Braun Biotech fermentation vessels which are longer and have a slightly different internal design. In order to seal properly, the o-ring on these sensors has been moved closer to the tip of the sensor. Also available as D430 with straight connector.

This Broadley-James D435 Dissolved Oxygen Sensor is designed for use with B. Braun fermentation vessels which are slightly longer than the standard length and have a different internal design. As such they need slightly different sensors, hence the D430 with straight connector and D435 with right-angled connector. In both of these sensors the o-ring has been moved closer to the tip in order to create a better seal.

The sensor fits directly into the vessel, eliminating the need for a housing, reducing contamination risks. Few accessories are required. The modular design allows quick replacement of any part, making it easy to maintain and repair the sensor. OxyProbe dissolved oxygen sensors carry a 1-year warranty.

This Broadley-James D445 dissolved oxygen sensor has a right angle connector. This low profile design provides:

  • Protection against cable fatigue
  • Improved grip for sensor extraction
  • Increased clearance between vessels
  • Reduced random sensor mobility on flat surfaces (won’t roll off the table)

Specification

  • 316L Stainless Steel
  • Serialized for traceability
  • RA32 finish with electropolish on wetted parts
  • External EPDM o-ring
  • Secured retainer ring

How to choose a sensor

  1. Confirm the vessel has a 25 mm B. Braun Biotech side port.
  2. Determine how far the sensor should extend into the vessel. For most process media, the minimum length is optimal. However, if the media is viscous and tends to coat the inner wall of the vessel, a longer length may provide better performance.
  3. Decide whether a right angle connector is preferred or a straight connector.
  4. Choose cable length and connector. All DO sensors require cable and connector assemblies.

It is important to maintain the sensors by inspecting and calibrating them regularly. The membrane cartridge should be checked and refilled prior to every use.

Compatible Cables

The D435 DO Sensor uses a D4 connector. This industry standard connector was the first, and is still, the best choice for DO sensors. We recommend the following cables for use with the D435 Dissolved Oxygen sensor:

Cable Type Sensor connector & Device Connector Device Terminal
D4 plug to Lemo 6
DO Cable D4 to Crimped Ferrules

The internal seals of an Oxyprobe are all mechanical seals using o-rings. There are no adhesives to leak or fail in process, making this a more rugged and reliable sensor. Replacing the cathode is also much easier and faster since there is no sealant to clean from the threads. No sealant also makes the job of replacing the cathode much faster and cleaner.
