About this category
HVAC Transmitters Overview
HVAC transmitters convert physical measurements into signals the BMS can use. This page brings together transmitters for every common measurement in building automation.
By measurement
- Differential pressure: air DP transmitters for filters, fans and clean rooms, and water DP for pumps and heat exchangers.
- Airflow: DPT-Flow airflow transmitters, air velocity transmitters and airflow probes.
- Temperature: LL series and room transmitters.
- Humidity: room, duct and outdoor humidity.
- CO2 and air quality: CO2 sensors and VOC sensors.
Controllers built in
The Produal DPT-Ctrl keeps fans, VAV systems and dampers at constant pressure or flow, and the RTX-CO2 room transmitter has a built-in P/PI controller.
FAQ
Common questions
Which output should I choose for my BMS?
0 to 10 V is common in building automation; 4 to 20 mA suits long cables. Many Produal models also offer Modbus RTU.
Can one transmitter measure several values?
Yes. For example, the DPT-Dual-MOD has two pressure sensors, and RTX room transmitters combine temperature, CO2, humidity and VOC.
Are the transmitters field-configurable?
Most Produal transmitters have field-selectable ranges and outputs, set by jumpers, menu or app.
