Optimise HVAC control with advanced pressure sensors

Pressure sensors are integral to efficient HVAC systems, providing accurate monitoring and control of air and fluid pressure. These sensors help maintain consistent flow, balance system performance, and prevent overpressure or vacuum conditions. Accurate pressure measurement is essential for optimising energy usage, ensuring occupant comfort, and protecting HVAC equipment. 

 

Key benefits of HVAC pressure sensors from Belimo

Incorporating high-precision pressure sensors into HVAC systems offers several critical benefits:

  • Flow optimisation

    Enables precise control of both airflow and fluid dynamics in ducted and piped systems. 

  • Energy efficiency

    Supports variable air and water flow control for reduced energy consumption and operational cost. 

  • System safety

    Detects abnormal pressure conditions, preventing equipment damage and operational failures. 

  • Compliance & monitoring

    Helps meet regulatory standards in healthcare and industrial HVAC systems. 

  • Integration ready

    Supports analogue (0-10V, 4-20mA) and digital (Modbus, BACnet) outputs for seamless building management system integration.

Applications of HVAC pressure sensors

Pressure sensors are crucial for HVAC system monitoring and control in diverse settings:

  • Commercial buildings

    Optimising airflow and pressurisation in offices, retail spaces, and educational facilities. 

  • Industrial HVAC systems

    Monitoring process environments with strict flow and pressure requirements. 

  • Cleanrooms & healthcare facilities

    Maintaining positive or negative differential pressure in critical zones.

  • Data centres

    Ensuring optimal pressure in cooling systems to protect sensitive IT equipment. 

Selecting the right pressure sensor for HVAC applications

When selecting a pressure sensor for HVAC systems, consider the following specifications:

  • Type of pressure

    Choose between absolute, differential, or overpressure sensing depending on the application.

  • Measurement range

    Ensure the sensor’s range aligns with system requirements for air or liquid pressure. 

  • Accuracy and stability

    High-resolution sensors provide stable, low drift performance over time.

  • Output signal compatibility

    Select appropriate output format (analogue or digital) for control system compatibility. 

  • Environmental durability

    Durable, sealed designs with IP-rated protection for demanding HVAC environments.
