High-accuracy temperature transmitters

This is a temperature transmitter with a measurement accuracy that is unique in today’s market. Its accuracy is ±0.3 across a wide temperature range. This cutting-edge technology enables compliance with European certifications such as LEED (ANSI/ASHRAE Standard 62.1-2022), BREEAM, RESET grade B and WELL (WELL v2™).

The RTX transmitter can be upgraded into a four-in-one probe with CO₂, relative humidity and VOC measurement. A PIR sensor can also be added. It operates with Modbus RTU and BACnet SMTP communication, both with BTL certification.

The device includes two digital inputs that allow connecting external transmitters and sensors to the RTX-D to expand its monitoring and control capabilities. The four 0–10 multifunctional analogue outputs are freely configurable. It also features a relay output.

The integrated P/PI controller can manage, for example, heating, cooling, ventilation or VAV applications. The control output can be regulated based on a measured value or on selected set values.

The RTX features a high-precision measurement technology patented by Produal, which evaluates installation quality with an indicator from 1 (best) to 4 (worst) to indicate measurement reliability.

“The latest generation of Produal room transmitters is equipped with new sensors that allow the device to react to changes in the surrounding air. It can even detect unusual airflow that cools the device, enabling compensation of the readings and delivering higher accuracy. Minimising measurement errors directly translates into energy savings by avoiding unnecessary heating or cooling.” — Anti Salli, Product Manager.

The RTX-D room transmitters with touch screen make indoor air quality monitoring intuitive, accurate and efficient, helping you create healthy and comfortable indoor environments while complying with the strictest regulations.

The transmitter’s 2.8" touch screen displays real-time measurement values at a glance. The user interface, configurable with up to six different screens, allows each view to be tailored to the user’s needs.

You can configure the interface to display measurement information, adjust setpoints and increase ventilation. It is also possible to customise the interface colours and the screensaver functionality.

With the MyProdual mobile app, it is possible to quickly configure and commission transmitters, as well as update the firmware. The app also provides a complete overview of the lifecycle and maintenance data of each device. It can be downloaded for free on Android via Google Play and on iOS via the App Store. To perform this configuration, an updated MyTool Connect Bluetooth dongle is required to connect to the transmitters.

“When installing or adjusting an RTX device, it connects to the cloud via a Bluetooth dongle. If the dongle is removed, the transmitter operates independently. Remote use and configuration are ensured through our network, and information security requirements are covered by the hardware of all our devices.” — Anti Salli, Product Manager.

In many installations, such as hospitals or laboratories, precision is non-negotiable. Reliable data is essential to control the indoor climate, which is vital for working under optimal conditions. This new range of room transmitters meets the strictest requirements of hospitals and research centers.

This level of accuracy allows for better building management and an efficient solution through automation of installations, optimising the building ecosystem and minimising costs and environmental impact. For example, it has been shown that a one-degree variation in ambient temperature can affect heating costs by up to 5%.

Another important aspect is comfort and health in buildings with high public occupancy, such as schools, libraries, offices or shops. In these indoor spaces, many harmful particles (VOCs) and carbon dioxide can accumulate, causing health issues and jeopardising people’s well-being. The new RTX-CO₂ room transmitter measures CO₂ with high accuracy and outperforms other CO₂ transmitters on the market in temperature precision.
