What is a Dwyer Sensor? Applications in HVAC & BMS Systems

In modern control systems such as HVAC and BMS, sensors play a vital role in monitoring and optimizing operations.

What is a Dwyer Sensor?

Dwyer sensors are measurement devices manufactured by Dwyer Instruments (USA), designed to monitor physical quantities such as pressure, airflow, temperature, humidity, CO₂, VOCs, and more. These sensors are widely used across industries, especially in HVAC (Heating, Ventilation, and Air Conditioning) and BMS (Building Management Systems).

Key Features of Dwyer Sensors

• High accuracy and reliability
• Fast response to environmental changes
• Compact design, easy to install and maintain
• Multiple output options: analog, Modbus, BACnet, etc.
• Long lifespan, stable performance in harsh conditions

Applications of Dwyer Sensors in HVAC Systems

In HVAC systems, Dwyer sensors play a crucial role in:

1. Air Pressure Monitoring (Differential Pressure)

• Measure pressure differences between zones to adjust airflow
• Detect clogged air filters, ensuring efficient air circulation

2. Temperature & Humidity Control

Provide precise readings for optimal climate control

Ideal for cleanrooms, cold storage, laboratories, and other sensitive environments

3. Airflow Monitoring

• Ensure appropriate air volume in each area
• Save energy while maintaining performance

Applications of Dwyer Sensors in BMS Systems

BMS systems manage and control building equipment centrally. Dwyer sensors act as the “eyes” of the system, enabling accurate and safe operation.

1. Centralized Monitoring Integration

• Support Modbus and BACnet for seamless connection to BMS
• Deliver real-time data for analysis, alerts, and automatic adjustments

2. Indoor Air Quality (IAQ) Monitoring

• CO₂ and VOC sensors detect indoor pollution levels
• Enable BMS to automatically control fans and air filtration systems
