• Measure process concentration in etching, coating, treatment and cleaning bathes
• Monitor the quality in photoresists
• Control the concentration blending of covering emulsions and suspensions

LiquiSonic products have proven very effective throughout the entire process in the semiconductor industry. Inline, real time monitoring provides the means to achieve maximum yield of consistent quality bathes, and to avoid product loss. The inline validation features of our systems ensure a high degree of process safety and traceability. The PFA design of our sensors minimize ion contaminations.

Unbeatable Utilization Rates
Where accuracy is critical, or where high pressure, high temperatures or sensitive processing environments make sampling impractical or impossible, SensoTech analyzers are ideal for monitoring inline processes.
LiquiSonic sensors are engineered for tough industrial processes including Class I Division 1 Hazardous Area installations.

A rugged housing is crucial for protection and high mechanical stability. Depending on the sensor type, our housings are able to withstand temperatures up to 200 °C or 392 °F, rated pressures up to 500 bar or 7,250 psi and are resistant to lye, acids and solvents.

The fundamentals for this quality are the high-grade materials used such as stainless steel, PTFE and PFA, alloy steels or tantalum. The sensor design consists of one homogenous body and requires no gaskets.

Well connected
Our sensors may be equipped with all common process adapters and fittings and 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 direct in every tube size.

Because the measuring technology works independent from colour, 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 be easily 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 when the sensor is replaced or after the process conditions change.

This concept ensures the return of your investment, and decreases 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, 4-20 mA in 2-wire loop power (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.
