Room humidity transmitters, also known as room humidity transducers or room humidity sensors, play a key role in monitoring and controlling humidity in indoor applications. Our room humidity transmitters provide precise measurements and standardized output signals, optionally with additional temperature measurement.
We have compiled this guide for you to explain what to consider when selecting, purchasing, installing, and operating your room humidity transmitter.
What is a room humidity transmitter?
A room humidity transmitter measures indoor humidity and converts it into a standardized electrical signal (e.g., 0-10 V or 4-20 mA). This data is sent to control systems or display units to monitor humidity levels precisely. It can also optionally measure temperature and is particularly suitable for offices, residential buildings, and industrial environments. You can find an overview of our humidity transmitters here.
For which applications do I need a room humidity transmitter?
Room humidity transmitters are used in various indoor applications, such as offices, residential buildings, and industrial environments. They help monitor the indoor climate to ensure optimal conditions for comfort, energy efficiency, and product quality in industrial processes. In laboratories, they support a controlled environment for sensitive testing.
Benefits of room humidity transmitters compared to other transmitters
Room humidity transmitters are specifically optimized for precise indoor monitoring. They offer high measurement accuracy and are ideal for controlling indoor climate and humidity. Compared to outdoor transmitters, they are designed for less extreme conditions but still provide reliable measurements and long durability. The various designs, such as the design version, also integrate well visually into high-end indoor spaces.

Advantages of the different designs
Room humidity transmitters come in three designs, each offering different advantages. The classic version with the Baldur 1 housing is a proven and cost-effective solution ideal for standard applications. The Baldur1 housing with display version allows on-site reading of measurements, which is particularly useful in environments where quick monitoring is necessary. The design housing (Frija1) stands out with its modern, rounded design, making it suitable for applications where aesthetics play a crucial role.
What factors affect the lifespan and performance of a room humidity transmitter?
Factors such as dust, dirt, and high humidity can affect the lifespan and performance of a room humidity transmitter. Regular maintenance, cleaning, and possibly calibration can help ensure optimal performance and longevity.
Where can I find all the technical data for the room humidity transmitters?
All technical data, such as data sheets, user manuals, and declaration of conformity, can be found on the respective product pages or here. These documents can be downloaded directly.

How is a room humidity transmitter installed?
For precise measurement of room temperature and humidity, it is essential to consider both the temperature dynamics and humidity dynamics within the room. Air circulation should occur exclusively through the openings in the housing cover. Therefore, the transmitter should be installed away from objects or obstacles that could block airflow. Also, avoid uncontrolled air currents (drafts) by not installing the device near doors or windows. The transmitter should not be mounted on a colder exterior wall to prevent inaccurate readings. The device should only be used in pollutant-free, non-condensing air (< 95% RH).
