Product Specifications

Technical details and manufacturing context for Analytical Sensor Array

Definition

The Analytical Sensor Array is a component used in Process Analytical Technology (PAT) modules within chemical manufacturing. It integrates multiple specialized sensors in a coordinated configuration to enable real-time, in-line measurement of various chemical, physical, and biological parameters during production. This supports quality-by-design principles and continuous process verification by providing comprehensive data for process control and optimization. The array typically includes sensors such as spectroscopic, electrochemical, optical, or thermal types, which simultaneously detect different analytes or parameters. Data from individual sensors is collected and processed through a central control system, allowing for multivariate analysis and holistic process monitoring. The system is designed to be configurable, with the number of sensors ranging from 4 to 8 channels, depending on the process requirements. Key specifications include a pH measurement range of 0–14 with an accuracy of ±0.02 pH at calibration point, and a temperature measurement range of -40 to 150 °C with an accuracy of ±0.5 °C over the full range. The response time for 90% of the final value is ≤5 seconds. The operating temperature for the electronics is -20 to 60 °C, while the operating pressure range is 1.0–1.6 MPa. The enclosure offers ingress protection rated IP65–IP67 (per IEC 60529). The supply voltage is 24 V DC ±10% with reverse polarity protection, and typical power consumption is ≤15 W. The output signal is 4–20 mA, with HART protocol available. Wetted parts are typically made of 316L stainless steel (per ASTM A240), with optional Hastelloy C-276. The weight ranges from 5 to 10 kg depending on configuration. Materials used in the sensor array include silicon, stainless steel (316L), optical glass, and polymer composites. These materials are selected for compatibility with chemical processes and durability. It is important to verify model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are reference ranges for directory purposes.

Working Principle

The sensor array operates by deploying multiple sensing elements—such as spectroscopic, electrochemical, optical, or thermal sensors—that simultaneously detect different analytes or parameters. Each sensor generates a signal proportional to the measured parameter. These signals are collected and processed by a central control system, which integrates the data to provide a comprehensive view of the process. The integrated data enables multivariate analysis, allowing operators to monitor process stability and detect deviations in real time. The array is designed for in-line operation, meaning it is directly installed in the process stream, providing continuous measurements without the need for sampling. The central control system can be configured to trigger alarms or adjust process parameters based on the sensor readings, supporting automated process control.
