The unique, cutting-edge Vaisala sensor technologies are manifested throughout our versatile range of products. The accuracy and long-term stability of Vaisala sensors are absolutely the best of class within the industry.
Learn about the uses of outdoor humidity sensors in HVAC applications. Evaporative cooling and economizers are widely used and indeed required by some standards. However not all humidity sensor are suitable for this type of measurement.
The goal of energy efficiency and the need for good indoor air quality intersect with the application of demand-controlled ventilation systems. What are the future requirements for Demand Controlled Ventilation and Indoor Air Quality?
Listen to our on-demand webinar on the requirements for the CO2 sensors in different standards and certification schemes like ASHRAE 90.1 and LEED.
Industries depend on sensor measurements to help meet goals of efficiency and automation, and the responsibility to maintain those measurements has a direct effect on those outcomes. As with all precision instrumentation, environmental and process measurement sensors are not maintenance-free, and require service to ensure that they provide reliable and accurate data.
In this webinar, Michael Gantert from Munters and Anu Kätkä from Vaisala will discuss the importance of measurement accuracy to maximize energy efficiency of data centers.
Discover the advantages of the CARBOCAP technology over other infrared CO2 measurement technologies. Learn how CARBOCAP actually works and how this technology could help you.
Many people working in the HVAC field know about relative humidity (RH) as a parameter used in HVAC controls. Relative humidity, however, is not always the best option as a control parameter. At times there are other choices that will make the conditions more stable or the system commissioning easier.
Accurate measurement of relative humidity and temperature is critical to the optimization of HVAC performance. If the readings of outdoor and/or indoor humidity sensors are off, both energy efficiency and human comfort may be compromised.
Heating, ventilation, and air conditioning (HVAC) is typically not considered a challenging application area when it comes to CO₂ sensors. While it’s true that ambient conditions are mostly benign, sensors still need to be reliable, easy to maintain, and offer long-term measurement stability.
This is the second in a series of three blog posts looking at common pitfalls when installing HVAC sensors, focusing on physical measurement errors that are caused by incorrect installation. This post focuses on common installation errors for HVAC duct sensors.
There are some helpful rules of thumb to help us understand how RH works at a basic level, though it’s important to remember that unless you’re in a closed system such as an environmental test chamber, other factors can affect results.
All gases in the environment will interact with a humidity sensor and potentially cause drift. Water needs to get in and out of the sensor, which means that other gases can too. In general, any strong smell is a warning sign that something is evaporating.
