## [Industrial filtration](/en-INT/solutions/filtration-industrial) ![Filtration industrial](/sites/default/files/entityone_paragraphs/images/SOLUTION_Intro_468x468_Draft.png) ## Air handling unit filter monitoring Ensuring good air quality in an industrial environment is essential to protect both employees and production. With this in mind, our instruments monitor air handling units (AHUs) and their filters. For preventive maintenance, continuous monitoring of the differential pressure (ΔP) across each filter in an AHU prevents problems associated with clogging. This not only protects the health of employees and the quality of the products manufactured, but can also have a significant impact on controlling energy costs. ## Parameters to be monitored - **Differential Pressure** Continuous Monitoring ## Continuous Monitoring Our differential pressure sensors monitor filter clogging and fouling to avoid production downtime due to maintenance. Our mechanical pressure switches can also generate the necessary alarms. Particularly reliable and equipped with a self-calibration system, our top-of-the-range electronic transmitters are recommended for more effective monitoring: transmission of measurements to a control system, display of values, visual and audible alarms, etc. [All our transmitters](https://sauermanngroup.com/en-INT/measuring-instruments/transmitters) [ read more about CP 210-R ](/en-INT/measuring-instruments/transmitters/pressure-transmitters/cp-210-r) [![cp210](/sites/default/files/styles/medium/public/images/CP210R-1.jpg?itok=lC4jADxJ)](/en-INT/measuring-instruments/transmitters/pressure-transmitters/cp-210-r) #### CP 210-R Differential pressure and temperature sensor The CP 210-R measures the differential pressure of air (and neutral gases), and is ideal for use in industrial and pharmaceutical applications.

Technicians need to be able to reach pressostats and pressure transmitters without difficulty, thanks to lightweight, practical and accurate equipment. Our portable manometers cover all the needs of technicians for spot measurements. Some simple, robust models can check the condition of filters. Other versatile and upgradeable models also measure speed and flow with modular probes.
