The AES-FPM Series is a compact, cost-effective particle sensing system designed for continuous monitoring in cleanrooms, controlled environments, laboratories, and contamination-sensitive manufacturing facilities. It provides real-time particle data and a four-level LED display for quickly assessing environmental cleanliness.
The AES-FPM Series is available in configurations that detect airborne particles larger than 0.3 μm or 0.5 μm. It can also detect particles larger than several micrometers as a reference measurement.
The AES-FPM-1 through AES-FPM-4 models detect particles larger than 0.3 μm and use a 60-second output averaging time. The AES-FPM-51 through AES-FPM-54 models detect particles larger than 0.5 μm and use a 300-second output averaging time. Their available outputs and communication options correspond across the paired models.
The AES-FPM monitors cleanliness levels from Class 1,000 to Class 100,000. Class 1,000 measurements are provided as reference information. Its four-level LED display allows operators to quickly identify changes in particle concentration.
The AES-FPM is intended for continuous particle monitoring, cleanliness trending, and detecting abnormal environmental conditions. It does not replace a compliant particle counter or the testing procedures required for formal cleanroom classification and certification.
Available configurations include alarm output, Ethernet, 1–5 V analog output, Wi-Fi, and RS-485. The specific connections depend on the selected monitor or sensor model, allowing the system to support standalone alerts, networked monitoring, and integration with compatible control or data-acquisition systems.
The AES-FPM-2, AES-FPM-52, AES-FPM-4, and AES-FPM-54 include Ethernet connectivity. The AES-FPM-4 and AES-FPM-54 also include Wi-Fi for additional network flexibility.
The AES-FPM-3 and AES-FPM-53 provide a 1–5 V analog output. These models can be integrated with compatible building management, SCADA, control, or data-acquisition systems that accept analog signals.
Yes. The AES-FPM-2, AES-FPM-52, AES-FPM-4, and AES-FPM-54 support optional temperature and relative humidity monitoring when connected to the CHU-L151-11A-AES sensor.
Yes. Multiple AES-FPM monitors can be installed at critical locations throughout a cleanroom, laboratory, production facility, or equipment area. Ethernet-enabled models are particularly well suited for integration into networked, multi-point monitoring systems.
The AES-FPM updates its displayed and transmitted data every second. The output averaging time is 60 seconds for 0.3 μm models and 300 seconds for 0.5 μm models.
Compatible models can display particle concentrations in particles per cubic meter (pcs/m³), particles per cubic foot (pcs/cf), or particles per liter (pcs/L). Reference measurements for particles larger than several micrometers are fixed at particles per minute (pcs/min).
The detachable sensor design allows a sensor to be replaced with a calibrated spare while the original sensor undergoes service or calibration. This helps reduce monitoring interruptions and maintain continuous environmental coverage.
The AES-FPS detects particles larger than 0.3 μm and uses a 60-second output averaging time. The AES-FPS-5 detects particles larger than 0.5 μm and uses a 300-second output averaging time. Both compact sensor units provide RS-485 communication.
Annual calibration of the particle sensor unit is recommended to support reliable measurements and consistent long-term performance.
The AES-FPM Series can be used in cleanrooms, pharmaceutical and biotechnology facilities, semiconductor and electronics manufacturing, food processing and packaging areas, precision-manufacturing operations, laboratories, data centers, server rooms, and other environments where airborne particles may affect products, processes, or sensitive equipment.
