Wireless Differential Air Pressure Sensor

Under pressure to perform?

Within 15 minutes, Monnit’s ALTA® Differential Air Pressure Sensor installs to remotely monitor filters, systems, and components. Be sure equipment is at peak—whether ventilating temporary medical crisis tents or an R&D cleanroom.

How an Air Pressure Sensor Works

This battery-powered pressure sensor measures the air pressure difference (with a range of -500 Pa to 500 Pa) between its dual ports. If, based on your parameters, the sensor measures a pressure differential between its ports, you’re alerted via text, email, or call. A difference likely points to a dirty filter or a machine/system that needs immediate service.

Differential Air Pressure Monitoring in Action

Remotely monitoring air pressure helps facility managers keep air filters clean, HVAC systems performing optimally, and extends system longevity.

But monitoring differential air pressure is about more than HVAC filter status.

Hospitals, pharma firms, and manufacturing facilities count on high-performance HVAC to manipulate air, contain infectious particles, and assist with proper filtration. This function is vital for the freestanding patient isolation structures that enable infectious patient treatment and maintain pharmaceutical purity.

Choose from the enterprise-ready AA model or an industrial-grade air pressure sensor below to keep the pressure on.
