  • supply reliable and real-time data about solvent concentrations,
  • measure precisely the content in nutrient solutions, emulsions and suspensions,
  • monitor online the concentration of active ingredients, vitamins and proteins,
  • are used as detectors or to monitor eluate concentrations in HPLC processes,
  • detect phase interfaces by product identification in vessels and pipes,
  • control crystallization processes for the reproducible generation of crystal sizes and the purification of substances.

Unbeatable utilization rates

in the pharmaceutical industry set high demands on housing, electronics and sensor technology. Our application specialists fit our systems to your requirements because all components can be engineered for the existing process conditions.

LiquiSonic® sensors provide a stable and reliable measurement. Autoclavable or CIP/SIP, our sensors are specially engineered for use in laboratory- pilot- or production –scale reactors and conform to all FDA, 3A standards or EHEDG recommendations.

, real-time measurement eliminates the need for sampling, eliminating volume loss and dilution errors in addition to reducing the risk of contamination. LiquiSonic® allows you to automate manual operations and achieve a new level of productivity and process control.

fundamentals for this quality are the high-grade materials used such as stainless steel with electro polish finish. The sensor design consists of one homogenous body and requires no gaskets.

Well connected

sensors may be equipped with all common process adapters and fittings like Tri-clamp, Ingold or Varivent, and can be used under the most complex application conditions.

By changing immersion lengths or the process adapters, our sensors fit into tanks and vessels of almost every design as well as directly in any tube size.

A suitable entry point into the process also results from incorporation of the LiquiSonic® sensor into the bottom outlet valve of the company SchuF. So measuring directly in the vessel without additional process connection is possible. Offered under the brand MultiProbe™ the combination of sensor and valve is an ideal solution for process analytical applications in the pharmaceutical and fine chemical industry.

Because the LiquiSonic® measuring technology is not dependent on color, turbidity or other optical attributes, the user will have no limitations, even under the most difficult application conditions.

Products and process may change

Every LiquiSonic® system can easily be adapted as various process conditions are modified. The Controller software manages up to 256 various product characteristics. Depending on the user access rights, these characteristics may be activated after the sensor replacement or after a changing of the process conditions.

concept ensures the return on your investment, and decrease your response time on changing boundary conditions. For new applications, you can create a new calculation model using process reference values together with our highly sophisticated SonicWork software.

Individual interfaces

SensoTech is able to offer all current and emerging standards of signal processing. For continuous concentration and density measurement, 4 … 20mA in 2-wire loop powered or 4-wire technology, Profibus PA or Foundation Fieldbus are available. For alarm level detection and switching a non-contact output or a relay can be configured. SensoTech analyzers can always match your installation needs.
