Applications
- Cleanrooms: In cleanrooms and other controlled environments, maintaining a specific pressure differential is critical to prevent contamination. Low range DP sensors are used to monitor the pressure difference between different zones, ensuring proper airflow and preventing the ingress of particles.
- HVAC Systems: These sensors are used to optimize HVAC system performance by monitoring pressure differences across filters, ducts, and air handlers. This data helps to identify clogged filters, leaks, and imbalances, improving energy efficiency and indoor air quality.
- Filter Monitoring: Low range DP sensors are commonly used to monitor the pressure drop across filters in various applications, including industrial processes, medical facilities, and air purification systems. By measuring the pressure difference, the sensors can indicate when a filter is becoming clogged and needs to be replaced.
- Leak Detection: These sensors can be used to detect leaks in sealed systems, such as pipelines, tanks, and enclosures. By monitoring pressure differences, they can identify even small leaks, preventing costly damage and ensuring safety.
- Flow Measurement: Low range DP sensors can be used to infer flow rates by measuring the pressure drop across a flow element, such as an orifice plate or Venturi meter. This is particularly useful in applications where low flow rates need to be accurately measured.
