Throughout the entire HVAC field, there are a variety of applications that use differential pressure transducers. With rugged stainless-steel housing, an isolated electrode, and a stainless-steel diaphragm, Setra’s sensors can be used in several of these applications.
Filter Status
Filter status has never been more important than it is today. With increased MERV ratings to combat the pandemic, filters are more costly and changing the efficiency profile of systems around the world. Continuously monitoring the pressure drop across a filter alerts a building automation system (BAS) that a filter needs attention.Differential pressure transducersare a cost-effective and accurate way to measure and maintain a system. The typical range for these sensors is 1” WC.
Air Flow
Increasing air flow and air changes are also increasingly crucial in today’s world. With recommendations to increase fresh air change rates to reduce risks of COVID-19, accurate air flow measurement is key to maintaining a safe environment while still operating efficiently. Since the flow rate has an exponential component, a highly accuratedifferential pressure transducer是测量系统或空气流量站内流量的一种经济有效的方法。这些传感器的典型范围是5“WC。
Room Static
保持适当的压差对于管理空间的性能至关重要。无论是实验室，甚至是建筑物的大堂区域，保持压差在指定的压力范围内对安全很重要。Transducersare a key component to the air handlers, economizers, and overall building automation system, as they help to measure pressure and give feedback for proper building control. The typical range for these sensors is ≤0.25” WC for uni or bi-directional flow.
Stairwell Pressurization
For a smoke free stairwell in the case of a fire emergency, proper differential pressure is critical. When a fire is detected, the building’s HVAC system plays a key role in ensuring building occupants can exit the building safely.Differential pressure transducers在反馈回路中至关重要，即使在灭火系统活跃时，也能保持楼梯井内的正压力。这些传感器的典型量程为单流量或双向流量≤0.25 " WC。
