Sentera – your partner in HVAC control solutions

Potentiometers with minimum and maximum limit, working from low to high speed or vice versa, with 0-10 volts, 0-20 mA or PWM output, infinitely adjustable or with adjustable steps (…) were already part of our assortment. Today we have expanded our potentiometer family with the SDP-M010 series that are equipped with Modbus RTU. As a result, not only are the settings available via the Modbus registers, but from SenteraWeb or your Building Management System you can also read the position of the potentiometer and even overwrite the output.

For the open house at one of our customers, we built a VAV demo unit in which various Sentera product groups are incorporated to work together as one solution. To explain the complete operation of this installation step by step, we have made a detailed video which you can watch on our Youtube channel. Check out the full article for more information.

Sentera has a wide range of products and solutions to control fans and monitor indoor air quality. Our product range has a modular structure, which offers enormous advantages. Sentera products are easy to install and they can work stand-alone. If the need changes, additional components can be added afterwards. The connected devices exchange information and work seamlessly together.

With the ErP-directives becoming more and more important, there will be a shift from AC-motors towards EC-motors which are much more energy efficient. We are therefore constantly developing new products and revising existing products to be able to control these EC-motors as accurately as possible.

The use of an efficient ventilation system in livestock farming not only improves animal welfare, but also improves returns. After all, such a ventilation system takes care of the removal of ammonia, maintains the relative humidity and regulates the temperature. Sentera offers numerous solutions in the form of sensors and fan speed controllers with an IP54 or IP65 classification. Our equipment can be used under the most demanding conditions and enables an efficient and demand-driven ventilation system.

The purpose of ventilation is to supply fresh outside air and extract stale air and pollutants from inside. The supply of fresh air can be seen as the first step towards good indoor air quality. However, a ventilation system is not a guarantee for good indoor air quality. In this article, we discuss some important points to consider.

We should save our planet for future generations. In the Building Industry we should construct our houses and offices as much energy efficient as possible to reduce CO2 emission.

The Sentera ACT-H-125 is a round motorized control damper for air ducts with a diameter of 125 mm and is equipped with an RJ45 socket and a classic terminal block. The damper blade position can be controlled by analog signal or Modbus RTU communication. The ACT-H-125 can be combined with many Sentera sensors. This ensures optimal demand based control of the ventilation system.

Internet of Things - or IoT - refers to the billions of physical devices around the world that are now connected to the internet, all collecting and sharing data. The IoT is a giant network of connected things and people – all of which collect and share data about the way they are used and about the environment around them. The Internet of Things is making the fabric of the world around us more smarter and more responsive, merging the digital and physical universes.

The Sentera DPS differential pressure sensor guarantees the display of the actual and real air flow rate in function of the occupancy rate of a room or building

Given the current circumstances (Corona virus, polluted air, ...), monitoring indoor air quality is strongly encouraged. CO2 meters are particularly suitable for controlling a ventilation system because they indicate whether there is sufficient fresh air in the room. Suddenly you can buy CO2 meters on every street corner. They are available in different price categories, sizes, types, etc. How do you select the right CO2 sensor for your project?

CO2 and VOCs are generally known as 2 factors that contaminate the air that we breathe. Now studies find that yet another substance, hazardous to our health, moves about airborne: toxic ‘forever chemicals’ or PFAS.

Sufficient fresh air supply is not only important for the feeling of well-being and for optimal functioning - it is also essential for your health. In closed indoor spaces, sufficient ventilation is necessary to minimise the risk of spreading the Coronavirus. Providing ventilation in existing buildings is, however, not always easy. Therefore exhaust ventilation can be a good solution in many cases.

HVAC sensors monitor indoor air quality. Based on specific measurements supply and exhaust fan speed is regulated to guarantee sufficient fresh air supply and to optimise the energy efficiency of the ventilation system.

Why is air quality in hospitals so important? A hospital is a place where both weak and healthy people come into close contact with each other. In Corona times, that is a frightening scenario that requires many precautions to make this possible in safe conditions. Monitoring indoor air quality is one of these precautions.

Sentera CO2 meters help to reduce the spread of the COVID-19 virus in this school in Sint-Niklaas, Belgium. Continuously measuring CO2 concentrations in classrooms provides certainty about indoor air quality. Good indoor air quality is essential to prevent the spread of the COVID-19 virus.
