2. Key Features

• 2 Channels Particle Size Monitoring: Simultaneously detects the mass concentration of particulate matter for PM10 and TSP with a rapid sampling time of 10 seconds.
• Precise Calibration: Manufacturer calibration benchmarking using the beta ray method reduces the need for secondary calibration.
• Efficient Sampling with Vacuum Pump: Equipped with a brushless vacuum pump ensuring a stable flow rate of 1.1 L/min for accurate measurements.
• Strong Anti-interference: Features an all-metal precision optomechanical structure design for enhanced anti-interference capabilities.
• Long Hours of Operation: Designed for durability, supporting over 10,000 hours of operation, especially in intermittent mode, due to industrial-grade core components like lasers and air pumps.

4. Setup and Installation

Proper installation is crucial for the accurate operation of the PMS 8+ sensor. Follow these guidelines:

1. Mounting: Securely mount the sensor in a stable location, away from direct sunlight, strong vibrations, and extreme temperature fluctuations. Ensure adequate airflow around the device.
2. Power Connection: Connect the sensor to a 12-24 VDC power supply using the designated terminals. Observe correct polarity to prevent damage.
3. Communication Interface: Connect the RS485 interface to your monitoring system. Refer to your system's documentation for specific wiring instructions.
4. Inlet and Outlet Terminals: Ensure the inlet and outlet terminals are clear and unobstructed. The pump-suction mechanism requires a clear path for air sampling.

5. Operation

The PMS 8+ operates automatically once powered and configured. Here are key operational aspects:

1. Power On: Once connected to the power supply, the sensor will initiate its startup sequence. Allow approximately 10 seconds for the sensor to stabilize before reliable readings are available.
2. Sampling Modes: The sensor supports both Continuous Mode and Intermittent Mode. The default setting is Continuous Mode. You can configure the sampling mode and sampling time (10 seconds to 24 hours) via the RS485 communication interface, depending on your monitoring system's capabilities.
3. Data Output: Particle concentration data for PM10 and TSP is transmitted via the RS485 interface. Consult the communication protocol documentation for details on data interpretation and integration with your system.
4. Environmental Conditions: Operate the sensor within the specified working temperature range of 0~50 ℃ to ensure optimal performance and longevity.

6. Maintenance

Regular maintenance ensures the accuracy and extends the lifespan of your PMS 8+ sensor.

• Cleaning: Periodically inspect the air inlet and outlet for any dust accumulation or obstructions. Gently clean with a soft, dry cloth. Do not use liquids or abrasive materials.
• Environmental Control: Maintain a clean environment around the sensor to minimize the ingress of large particles or debris that could affect the pump or laser.
• Calibration: The sensor is factory-calibrated. If you suspect a significant deviation in readings, contact Temtop support for guidance on re-calibration procedures.
• Storage: When not in use for extended periods, store the sensor in a dry environment within the specified storage temperature range of -10~60 ℃.
