Overview
The SentroPAT DA is a compact NIR analyzer for online monitoring of powder bin blending. It provides valuable process insights and can be used to determine blend end-point in real time, optimizing production efficiency. The system is compatible with many suppliers’ blenders and with most blender sizes.
The SentroPAT DA includes an internal battery, providing at least 6 hours of continuous operation on a blender, as well as internal wi-fi connections. This enables fully wireless connection on a blender. An internal gyroscope allows the system to only collect data when powder is likely to be in front of the process window the system mounts on to, which is typically added to a modified blender bin lid.
The SentroPAT DA includes a high-performance diode array spectrometer, covering the majority of the NIR spectral region. The system’s spectral resolution, long-term stability, and superior system-to-system comparability make it a reliable and robust NIR PAT solution for development and manufacturing. Data integrity is maintained through embedded buffering and seamless integration with plant IT systems, ensuring secure, real-time data transmission.

Frequent Asked Questions
Find answers to common questions about the SentroPAT DA and its applications in pharmaceutical manufacturing.
The SentroPAT DA stores the 600 most recently collected spectra in a buffer, which will be sent to the External PC once Wi-Fi communication is established. It is very rare that a single blend lasts 600 revolutions or more, so the liklihood of losing data during blending due to loss of Wi-Fi is very, very low.
No, the sources are intended to last the lifetime of the instrument. A second, redundant source has been added to the system and can be switched to via a software parameter change if an NIR source stops functioning, avoiding unnecessary service downtime.
It's hard to give a definite answer here without knowing specifics of the blender, it's associated enclosure, and how the SentroPAT DA will be mounted to the blender. Many customers have successfully integrated a SentroPAT DA on their small scale blenders, including V-blenders. If you have questions about your system, please reach out!
There are two ways to power the system. When connected to a power supply, the system automatically recharges its internal Li-Ion battery. Additionally, the battery can be easily swapped for a fully charged one. An external charger, which is included, allows charging additional batteries while the system remains in use. This is particularly useful for long operating periods without sufficient downtime for recharging.
In some cases, customers ensure continuous power supply by using slip rings on the blender.
