TurbiGuard AD 40

Technical Description – TurbiGuard AD 40

In-line Turbidity Monitor for Medium to High Turbidity 

The TurbiGuard AD 40 is used to measure medium to high turbidity. A single device covers the corresponding applications. The TurbiGuard AD 40 is calibrated with Formazin over the entire linearised measuring range. Simple configuration and communication via one of the available interfaces, from 4…20 mA current interfaces to bus systems, guarantee simple application and system integration. The TurbiGuard AD 40 comes in a new, fresh design with an integrated colour touchscreen display. This makes the TurbiGuard AD 40 easy to identify in the system. The status is displayed directly in the device at the measuring point. The security of the data on the new interfaces is guaranteed.

A Closer Look

A universally applicable device with a large measuring range, simple installation in a standard housing without tools, integrated measured value display and
maximum flexibility in configuration and communication -this is what modern process measuring devices look like today.

Precision Turbidity Measurement
Enables real-time monitoring of turbidity in a wide range of processes. Measures turbidity and detects any deviations early, helping to avoid off-spec batches.

The TurbiGuard AD 40 helps to ensure the quality of the end product.

 

Typical Applications Include:

• Turbidity measurement or monitoring in beverages such as beer, fruit juices
• Control of centrifuges, separators, whirlpools
• Filter performance and filter breakthrough monitoring
• Determination of the solids concentration
• Yeast propagation and dosing
