BELIMO LMV-D3-MOD

In contemporary HVAC installations, achieving accurate, efficient volumetric‑flow and damper position control is paramount—especially in variable‑air‑volume (VAV) systems serving offices, hotels, hospitals or cruise ships. The Belimo LMV‑D3‑MOD responds to this demand by combining three key components: a high‑precision dynamic differential‑pressure sensor (for airflow/pressure measurement), a modulating actuator (for damper positioning) and full communication capabilities in a single compact unit. This unified design simplifies installation, reduces wiring and improves both reliability and maintainability. For example, rather than installing separate pressure sensors, controllers and actuators, one LMV‑D3‑MOD module handles sensing, control and communication. With its bus interfaces—BACnet MS/TP, Modbus RTU or MP‑Bus—it integrates cleanly into a building‑automation system for real‑time monitoring, diagnostics and control. The modulating actuator supports 0/2…10 V analogue control or bus control, enabling hybrid operation. Its differential‑pressure measurement range (0…500 Pa) is suitable for typical VAV applications, and the IP54/NEMA2 enclosure ensures dependable field performance. Compared to alternatives that require multiple devices, the LMV‑D3‑MOD’s integrated approach reduces system complexity, shrink‑footprint, and total cost of ownership. HVAC contractors and system integrators gain faster commissioning, fewer components to spec and maintain, and superior performance for modern, networked air‑handling applications. belimo.com+1
