Produal RTX: High-accuracy room temperature transmitter with integrated PI control
The Produal RTX series is designed for environments where measurement accuracy and control stability are critical. With a base accuracy of ±0.3 °C and extensive configuration options, this transmitter is ideally suited for projects that must comply with strict standards such as LEED, BREEAM, and WELL (v2).
The RTX is more than a passive sensor; it is an active component within your building management system (BMS). Thanks to its modular design, you can select exactly the functionality your project requires, ranging from analog outputs to advanced bus communication. An extended RTX version with display is also available.
Technical highlights and functionalities:
- Superior measurement accuracy: The RTX offers a standard accuracy of ±0.3 °C, making it suitable for RESET Grade B and other certifications where high reliability of sensor data is required.
- Integrated P/PI controller: The transmitter features an onboard controller for direct control of thermal actuators, cooling valves, or VAV units. The output can be controlled based on the internal measurement or via a maximum selection of multiple sensor values.
- Multifunctional input: The RTX includes an input for connecting external passive sensors or transmitters. This allows the RTX to function as a decentralized I/O hub within the room.
- Flexible communication: Depending on the version, the RTX can be integrated via:
- Analog: 0…10 V or 4…20 mA outputs
- Modbus RTU: Full readout and configuration via RS-485
- BACnet MS/TP: Seamless integration into open automation protocols
- Optional PIR sensor: For occupancy-based control (e.g. switching between Comfort and Eco mode), the RTX can be equipped with a passive infrared sensor.
