What Is Active Filter Monitoring?

Active filter monitoring measures the differential pressure upstream and downstream of the filter. A differential pressure transmitter reliably detects how much the air flow is obstructed by the filter. If the pressure loss increases, this signals increasing filter contamination - the optimum time to change the filter can be determined objectively.

Why Filter Monitoring Is More Important Today Than Ever

Clean air and smooth processes are essential in modern ventilation systems and machines. Filters play a central role in this. But when is the right time to change the filter? Active filter monitoring using differential pressure measurement provides precise, continuous and automated information about the degree of contamination - protecting not only systems, but also people and processes.

Which Transmitters Are Used?

Which transmitters are used?

The following properties of a differential pressure transmitter are crucial for reliable active filter monitoring:

Measuring range in the Pascal range (e.g. 0-250 Pa or 0-1000 Pa)
Long-term stability with constant air flow
Compact design for easy integration
Robustness against temperature and humidity fluctuations
Signal variants: analog or digital via Modbus RS485t

Conclusion: Why Switch to Active Filter Monitoring?

A system for active filter monitoring is a small investment with a big impact: it increases operational reliability, reduces energy costs and helps to comply with hygiene and environmental standards. With differential pressure transmitters, you can identify the actual maintenance requirement - precisely, digitally and reliably.
