Baghouses and dust collectors are the workhorses of industrial air pollution control — and also some of the most maintenance-intensive equipment on a plant floor. A single torn filter bag, a plugged compartment, or a slow leak can go undetected for weeks under a traditional manual inspection schedule, quietly degrading filtration performance and pushing a facility closer to a compliance violation. Auburn's baghouse and dust collector monitoring instruments are designed to close that visibility gap, giving maintenance and operations teams continuous, real-time insight into exactly how each compartment of a baghouse is performing.
The Core Challenge: You Can't Fix What You Can't See
Baghouses typically consist of dozens or even hundreds of individual filter bags organized into multiple compartments. A leak in a single bag might represent a tiny fraction of total airflow, but left unaddressed it can escalate — abrading neighboring bags, increasing particulate loading on downstream equipment, and eventually contributing to a stack emission excursion. Traditional inspection relies on scheduled manual checks, opportunistic bag testing, or reacting only once a problem becomes visible or triggers an alarm elsewhere in the process.
The alternative is continuous, per-compartment particulate and differential pressure monitoring — instrumentation that tells you not just that something is wrong, but where and roughly how severe, well before it becomes a plant-wide issue. This shift from reactive to proactive maintenance is where Auburn's baghouse monitoring line delivers its clearest value.
Real-World Results: From 200 Hours to 14
Auburn documents a project in which baghouse-focused monitoring reduced the associated maintenance workload from around 200 hours down to just 14 hours for a cement industry application. That is not a marginal improvement — it represents a fundamental change in how maintenance teams allocate their time, moving from broad, labor-intensive manual inspection routines toward targeted interventions driven by actual sensor data. For plants running lean maintenance teams, this kind of efficiency gain can be the difference between keeping pace with preventive maintenance and constantly playing catch-up.
The Product Line: DynaCHARGE™-Powered Particulate Monitors
Auburn's baghouse portfolio centers on a family of particulate monitors, all built on DynaCHARGE™ triboelectric sensing technology, scaled to match different budget levels, feature requirements, and compliance obligations.
PM 100 PRO
At the top of the range, the PM 100 PRO is built for critical process control alongside EPA and MACT compliance requirements. It's engineered to consistently outperform comparable charge-based and optical instruments, and pairs an advanced processor and display with Auburn's MICS™ platform for a more complete monitoring solution — not just a single sensor reading, but a fuller data and diagnostics package suited to facilities where compliance stakes are high and downtime is expensive.
PM 100
The PM 100 delivers reliable particulate monitoring along with leak and flow detection, offering a solid set of core features, functions, and I/O connectivity through the MICS™ platform. It's a strong middle-tier option for facilities that need dependable continuous monitoring and basic diagnostics without necessarily requiring every advanced feature of the PRO model.
PM 1 PRO
Described as the benchmark for reliability in a standard particulate monitor and leak/flow detector, the PM 1 PRO is notable for being among the first loop-powered particulate monitors to offer EPA-certifiable self-tests. Loop power simplifies installation in facilities where running separate power to every monitoring point is impractical, while the built-in self-test capability supports ongoing compliance documentation without extra manual verification steps.
PM 1
At the entry point of the range, the PM 1 is positioned as strong value in a basic particulate monitor and leak/flow detector. Auburn positions its engineering and build quality as exceeding comparably priced alternatives, and its lower cost makes continuous monitoring economically viable even for smaller, "nuisance dust" collectors that might otherwise go unmonitored due to budget constraints — extending the visibility benefits of continuous monitoring beyond just the largest, highest-risk baghouses in a facility.
DP 20T / SP 20T — Differential and Static Pressure Sensors
Particulate monitoring is only part of the picture. Differential pressure across filter media is one of the most direct indicators of filter condition and airflow health in a baghouse or wet scrubber system. The DP 20T uses a durable ceramic diaphragm mounted on the dirty side of the process — for example, below the tube sheet in a baghouse — with a reference port routed to the clean side, providing a continuous differential pressure reading that reflects real filter loading conditions. The SP 20T variant is designed for measuring static pressure or vacuum rather than a differential reading, suited to applications where absolute pressure conditions matter more than the pressure drop across a specific filter stage.
Because ceramic diaphragm sensors are inherently resistant to clogging compared to some alternative pressure-sensing technologies, they hold up better in the same dirty, high-particulate environments where baghouse monitoring is needed most — reducing the false readings and maintenance interruptions that can come from sensor fouling.
Building a Complete Baghouse Monitoring Strategy
The most effective baghouse monitoring setups don't rely on a single sensor type. A combination of particulate monitoring (to detect leaks and bag failures) and differential/static pressure monitoring (to track overall filter loading and airflow health) gives maintenance teams a much richer diagnostic picture than either technology alone:
- Particulate monitors (PM 1, PM 1 PRO, PM 100, PM 100 PRO) catch leaks, tears, and breakthrough events at the compartment or unit level.
- Pressure sensors (DP 20T / SP 20T) track the gradual loading of filter media over time, helping teams plan bag replacement and cleaning cycles proactively rather than reactively.
- The MICS™ platform ties this data together, giving operators a centralized view across multiple monitoring points rather than a collection of disconnected readings.
Matching the Monitor to the Application
When specifying baghouse and dust collector monitoring instrumentation, a few practical questions help narrow the choice:
- How critical is this collector to compliance? High-stakes EPA/MACT applications typically justify the PM 100 PRO's advanced self-verification features.
- What's the budget and scale? For smaller or lower-risk dust collectors, the PM 1 or PM 1 PRO often deliver the necessary reliability at a more accessible price point.
- Is loop power a constraint? Facilities with limited power infrastructure at monitoring points benefit from the PM 1 PRO's loop-powered design.
- Do you need pressure data alongside particulate data? Pairing a DP 20T or SP 20T with a particulate monitor gives a fuller picture of filter and system health.
Conclusion
Baghouse and dust collector monitoring is where continuous instrumentation delivers some of the clearest, most measurable returns — not just in avoided compliance risk, but in dramatically reduced manual inspection time and more targeted maintenance. Whether the priority is top-tier compliance assurance with the PM 100 PRO, budget-conscious coverage of smaller collectors with the PM 1, or comprehensive filter health tracking with the DP 20T / SP 20T, Auburn's baghouse product line is built to turn a traditionally reactive maintenance task into a proactive, data-driven process.
