HVAC differential pressure transmitters are used to measure pressure differences in heating, ventilation, and air conditioning systems.
They help monitor airflow, filter condition, and duct pressure in HVAC applications.
These transmitters ensure efficient operation of air handling units and ventilation systems.
They are commonly installed in clean rooms, hospitals, laboratories, and commercial buildings.
The device converts pressure differences into electrical output signals for control systems.
HVAC differential pressure transmitters improve energy efficiency by maintaining proper airflow balance.
They are designed for low-pressure measurement with high accuracy and stability.
Compact and lightweight construction allows easy installation in confined spaces.
The transmitters support analog outputs such as 4–20 mA or 0–10 V DC.
Many models include digital displays for real-time pressure indication.
They are suitable for monitoring filter blockage and fan performance.
Durable housing materials provide long service life and environmental protection.
The transmitters are resistant to vibration, dust, and humidity in HVAC environments.
They can be integrated with building management systems (BMS) for automated control.
HVAC differential pressure transmitters play a vital role in maintaining indoor air quality and system performance.
HVAC differential pressure transmitters (DPTs) are precision instruments that measure the pressure difference between two points (e.g., across a filter or in a duct) and convert it into an electrical signal (4–20 mA, 0–10 V) for building automation systems. They are essential for monitoring airflow, filter status, and energy efficiency.
