Market launch of PhaseGuard ST 40 and TurbiGuard AD 40

Sigrist is pleased to present the new PhaseGuard ST 40 and TurbiGuard AD 40. These new devices will replace the previous models and offer numerous improvements and innovative functions.


Available models:

  • TurbiGuard AD 40 S1XX-0000.000: For medium and high turbidity.
  • PhaseGuard ST 40:
    • S2XX-0000.000: For medium and high turbidity
    • H2XX-8000.000: For very high turbidity levels


Areas of application
PhaseGuard ST 40:
  • Phase separation yeast/beer
  • Separator control for yeast separation
  • Dosing of kieselguhr

TurbiGuard AD 40:

  • Turbidity measurement on the lauter tun and whirlpool
  • At the separator
  • Before the kieselguhr filter or PVPP filter
  • Yeast dosage and yeast propagation


Important innovations and advantages of the new devices
Integrated display: Like all our new generation devices, the new models have an integrated colour display that directly visualises the turbidity value (TurbiGuard AD 40) or the device status (PhaseGuard ST 40).

Advanced user interface and simple parameterisation: In addition to displaying values, the main installation and maintenance operations can now also be carried out directly on the photometer. Advanced operation is simple using a smartphone or tablet via a point-to-point connection to PhaseGuard ST 40 or TurbiGuard AD 40.

New measuring head: Both devices are based on the established absorption measuring principle. The measuring head is based on the proven design, but has been redesigned and further improved in important details.

Process connection: The connection is still made via a VARINLINE connection. The new photometers are slightly smaller than their predecessors, which makes them easier to replace in the field.

Greater choice of communication options for process control: As before, analogue current interfaces (0/4...20 mA) are available, supplemented by all the new interfaces of the EdGe platform. (Modbus RTU, Modbus TCP, Profibus DP, Profinet IO, PoE).

With these new devices, we are continuing the success story of the PhaseGuard and TurbiGuard and continue to offer our customers reliable and innovative solutions.

We are convinced that these new devices will offer significant added value for applications. If you have any questions or require further information, please do not hesitate to contact us.
