Mechanical and Plant engineering

Analyzers for process monitoring

The LiquiSonic® analyzers are used in a variety of applications in the plant and mechanical engineering:

  • concentration measurement of coolants and lubricants, cutting oils and antifreezes
  • emulsion monitoring of drilling, cutting and lubricating oils
  • bath monitoring concerning industrial parts cleaning and surface treatment, 
    e.g. degreasing cascades, preservation processes or quenching
  • determination of density and fuel additives

Unbeatable utilization rates

LiquiSonic® sensors are robust, work maintenance-free and measure inline with high accuracy. In numerous industrial surface treatment and cleaning processes, the sensors are used to monitor continuously and in real time.

Advantages of online bath monitoring

for example:

  • the bath process documentation as an indirect proof of compliance with the relevant quality parameters "bath concentration" and "bath temperature",
  • the perfect bath care by optimum re-dosing of the cleaning agent, solvent or other process liquid in order to compensate losses of process liquid and water resulting from evaporation and discharge,
  • the efficient control of bath changes by online monitoring of the bath contamination degree.

The use of cleaning and treatment baths is common in various industries and processes. For example, single or multi-chamber systems or conveyor systems are used to remove film or particulate impurities  or to apply anti-corrosion liquids.
All technologies are realized within single or cascaded baths. The following process picture demonstrates the application of LiquiSonic® at relevant measuring points of a degreasing cascade.

Well connected

Our sensors may be equipped with all common process adapters and fittings and can be used under the most complex application conditions. By changing immersion lengths or process adapters, our sensors fit into tanks and vessels of almost every design as well as directly in any size tube. Because the measuring technology is not dependent on color, turbidity or other optical attributes, the user will have no limitations, even under the most challenging application conditions.

Products and process may change 

LiquiSonic® systems can easily be adapted to accommodate various modified process conditions. 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 when process conditions change. This concept ensures the return on investment, and decrease the response time on changing boundary conditions. For new applications, a completely new calculation model can be created by using process reference values.

Individual interfaces

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