## [Monitoring and regulation](/en-US/applications/air-conditioning-and-ventilation/monitoring-and-regulation) ![ventillation system](/sites/default/files/entityone_paragraphs/images/Monitoring-and-regulation_0.png) In critical settings, ventilation systems need to be monitored around the clock to make sure indoor air is being managed as optimally as possible. Here, monitoring involves preventing and detecting breakdowns and malfunctions of the air conditioning system. Measuring instruments also enable real-time regulation of the entire air conditioning system in a building, room by room. This application requires multifunction transmitters, or transmitters specially designed to measure a specific parameter. The regulation process therefore forms part of the Building Management System. In addition, it relies on SCADA (Supervisory Control and Data Acquisition) systems – a computerised environment that also optimises the building’s energy use by analysing data collected by our measurement instruments. That’s why Sauermann’s transmitters are open by design, meaning they have standard outputs – both analogue and digital. And our transmitters offer the ultimate in flexibility when it comes to BMS topology, structure and configuration. ![CTA-outdoor](/sites/default/files/entityone_paragraphs/images/Si-C320_CTA_outdoor_4.jpg) The aim is to regulate air quality parameters non-stop and around the clock, to achieve flawless indoor air quality management and to support preventive maintenance of the ventilation system. The awareness about indoor air quality has become one of the pillars of the developments of the HVACR industry. The impact that the design, control and maintenance of VAC systems have on each individual's health and well-being is known. It does have a direct influence on the energy efficiency too. Creating the best indoor air conditions following specific guidelines is the main goal of regulations like the ANSI/ASHRAE Standard 62.1. With a given set of specific procedures and engineering methods, the ANSI/ASHRAE Standard 62.1 provides the tools to design and manage VAC systems in non-residential buildings, delivering the outmost air quality. The continuous analysis of the key air parameters through measuring is an essential part to succeed in such important challenge. Sauermann's instruments have been designed to help you reaching this goal. Multifunction transmitters ## Multifunction transmitters Sauermann’s multifunction transmitters are great to measure differential pressure and psychrometric parameters simultaneously in specific VAC applications. These premium instruments deliver unmatched reliability and are built to withstand the test of time. Measuring differential pressure is especially important in buildings, helping to monitor filters in aeraulic networks. Some of these filters are HEPA or ULPA models, which are designed to remove airborne micro- and nano-particles including bacteria and viruses. Filters' efficiency decreases quickly as they get clogged, meaning they need to be monitored constantly for replacement planning purposes. These multifunction measurement instruments can also accommodate one or more additional probes for monitoring extra parameters (atmospheric pressure, temperature/humidity, air velocity and air flow, and CO/CO2/VOC concentration).

The Si-C320 housing is waterproof, rugged and resistant to vaporised hydrogen peroxide (VHP). It also features a colour touch screen for comprehensive viewing and advanced control of measurement parameters. In addition, measurements can be recorded and downloaded via the Sauermann Control application/software.

They are essential to both occupant comfort and the preservation of products in store rooms. The regulation of these parameters is therefore vital not only for health and quality purposes, but also for financial reasons, since regulating temperature and humidity is essential to achieve the energy efficiency standards set by recent environmental regulations. Likewise, effective monitoring helps to identify weak points in a building’s insulation. Sauermann has been supplying temperature and humidity transmitters for 45 years. All our models undergo strict reliability checks for both parameters before leaving our factories, with the results certified by our ISO 17025:2017-accredited laboratories in France. Buildings of all types rely on our expertise for indoor air regulation: factories, warehouses, museums, schools, hospitals, offices and more.

These measurements are taken at air filters and ducts, where differential pressure measurements can be used to deduce the air flow rate. The filters inside air treatment units get clogged at different rates depending on their filtration efficiency. Constant monitoring is vital for antibacterial HEPA and ULPA filters in particular. Differential pressure values taken between both sides of a filter indicate the extent of clogging and help to determine when the filter needs to be replaced as part of preventive maintenance planning – the process by which maintenance work is scheduled at the most appropriate moment in order to reduce or eliminate downtime. Building on its long-standing expertise in pressure measurement instruments, Sauermann’s solutions – connected digital manometers and liquid column manometers – cover the complete range of applications. Our digital manometers are ideal for recording values remotely and over time. All models feature a visual and audible alarm, and some come with an integrated display. Meanwhile, our liquid column manometers set new standards for durability and work without power supply, which makes them exceptionally resilient.

And crucially, it gives an indication as to whether the air change rate is sufficient in parts of the building where this is necessary. Having a regular circulation of fresh air is essential to keep the climate constant, especially in rooms containing equipment that radiates heat such as machines, power supply units and microcomputers. In other instances, it helps to remove cold air or chemicals released by particular products. That’s why Sauermann has developed advanced instruments for monitoring and recording air velocity and flow rate values in ventilation system pipes, covering both inlets and outlets. Our solutions also include DEBIMO blades, a renowned technology for calculating air exchange volumes in ventilated premises in real time.

CO2 concentration can be measured quickly and in real time, but capturing reliable measurements requires high-end CO2 sensors. Sauermann’s technology is totally reliable: non-dispersive infrared (NDIR) sensors integrated into instruments that are calibrated by our in-house metrological service. CO2 measurement is no longer exclusive to the most critical buildings. In fact, it is highly recommended in all public premises, including schools and offices. Scientists currently agree that a CO2 concentration between 800 and 1,000 ppm indicates a sufficient air change rate to reduce the concentration of bacteria and viruses suspended in the air, thereby mitigating the potential spread of airborne pathogens.
