Precision Monitoring for Clean Room
Airflow and Safety
Clean rooms are highly controlled environments designed to minimize the presence of airborne particles, contaminants, and pollutants. They are essential for pharmaceuticals, biotechnology, electronics, and aerospace industries. These rooms maintain strict cleanliness standards to protect sensitive processes, products, and research from contamination.
Clean rooms are classified based on the number and size of particles allowed per cubic meter of air, with higher classifications indicating more stringent cleanliness requirements. As industries evolve, there is a growing demand for more advanced and efficient clean rooms supporting cutting-edge technologies such as nanotechnology and advanced semiconductor manufacturing.
With the rise of pharmaceutical and biotechnology research, clean rooms are becoming increasingly sophisticated to meet the strict regulations and quality control standards necessary to produce sterile products, particularly in vaccine production and drug development. However, maintaining clean rooms presents several challenges. Factors such as fluctuating air pressure, inefficient airflow, faulty filtration systems, or equipment malfunctions can compromise the cleanliness of the environment, potentially leading to contamination, product loss, or operational downtime.
Pressure sensors are critical to the success and reliability of clean rooms. They monitor differential pressure between rooms and controlled zones to ensure that airflow remains consistent and contaminants are kept out of sensitive areas. Maintaining positive pressure in clean rooms prevents the entry of particles. In contrast, negative pressure is used in containment areas to keep hazardous substances from escaping. Real-time pressure monitoring enables early detection of any imbalances, ensuring corrective action can be taken before contamination occurs. Additionally, pressure sensors help verify that HVAC systems and air filtration are functioning optimally, providing accurate data to maintain compliance with clean room standards.
Unique Capabilities for Clean Rooms
The NimbleSense architecture was designed to maximize performance while also being flexible enough to easily insert application-specific capabilities. The result is a pressure sensor architecture with a very clear signal and practically no noise, leading to incredible accuracy, TEB, and long-term stability. Specific to clean rooms, we have implemented these additional capabilities:
Multi-Range™ technology
A single sensor can accommodate up to eight different pressure ranges to effectively measure pressure across a wide variety of airflow locations and environments
Advanced digital filtering
Multi-order filter that leverages advanced filtering capabilities at the front end to eradicate critical noise caused by fans, blowers, or other sources before they can impact system performance
Integrated 50/60 Hz notch filter
Neutralizes any power grid spikes or noise coming from AC devices that could interfere with sensor accuracy or system performance
Position insensitivity
Maintains consistent and highly accurate handheld readings regardless of movement or the physical orientation of the measurement device; rated with a positional sensitivity to within 0.25 pascal
Integrated closed loop control
Eliminates the need to design an external closed loop control system, which simplifies product design and reduces loop delays by up to 100x
Superior’s NimbleSense architecture enables us to develop unique products optimized for different markets. For clean rooms, we have created the following products. Our architecture is very flexible, so we can also develop custom solutions for your application.
