Air Filter Monitoring
Replace filters when they need it.
Not before. Not after.
Pressure-based monitoring tells you precisely when
a filter has reached the end of its useful life, saving energy,
cutting waste, and keeping airflow where it needs to be.
Air filters trap dust, dirt, and contaminants, and as they do, airflow decreases, and system strain increases. Left unmonitored, a clogged filter forces fans and motors to work harder, driving up energy consumption and accelerating wear. In HVAC systems, it means degraded indoor air quality. In industrial and automotive applications, it means reduced performance, higher fuel costs, and unplanned repairs.
The traditional response of scheduled replacements or visual inspection solves the wrong problem. Schedules ignore the actual filter condition, leading to premature replacements that waste money or missed changes that cause damage. By the time a performance decline is noticeable, the system has already paid a price.
Differential pressure sensors give you a direct, real-time measure of filter condition. As a filter loads with contaminants, the pressure drop across it rises, and that rise tells you exactly when replacement is needed, not sooner and not later. For accurate, repeatable readings across the very low pressure ranges that filter monitoring demands, the sensor you choose matters.
Superior’s Unique Capabilities for Air Filter Monitoring
The NimbleSense architecture was designed to maximize performance while remaining flexible enough to easily incorporate 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 HVAC systems, 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 air flow environments; change pressures ‘on the fly’
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
