Precise phase separation in the decanter: STMd-T rod probe in full PTFE technology

Efficient phase separation under extreme conditions – the STMd-T rod probe

Typical use of the application for phase separation

Highest reliability in phase separation for demanding chemical processes. The rod probe type: STMd-T from Aquasant is the ideal solution for process engineers who require the highest precision and reliability in interface measurement in demanding chemical processes. Thanks to its full PTFE design, this probe is particularly suitable for use in environments with aggressive chemicals.

This advanced probe ensures continuous phase control in glass-lined or PTFE-lined decanters by precisely measuring the phase height using impedance measurement. Whether emulsions, phase inversions or other complex process conditions – the STMd-T ensures reliable and optimal phase separation.

High-quality materials for extreme conditions

Adaptability is the key to success in the chemical industry. That’s why the STMd-T offers a customized sensor design that is precisely tailored to your process requirements to ensure maximum results and process reliability. The combination of stainless steel, Teflon sheathing and the FFKM (Chemraz) double sealing system ensures that the probe performs reliably even under extreme chemical conditions.

Precision in the measurement and differentiation of liquid phases

With the ability to accurately measure impedance, conductivity and dielectric constant (DK) as a sum signal, the STMd-T rod probe allows you to clearly distinguish between different liquid interfaces – from insulating to highly conductive products. This provides you with valuable data that can significantly improve the efficiency and quality of your processes.
