Differential Pressure Transmitters – Precision Airflow and Pressure Control

A Differential Pressure Transmitter is a sensor designed to measure the difference in pressure between two points in a system. Unlike a standard pressure sensor, which measures absolute or gauge pressure, a differential pressure transmitter provides critical information about pressure changes across a filter, duct, valve, or other equipment.

By continuously monitoring pressure differences, these devices are essential for process optimization, energy efficiency, and system safety.

Why Are Differential Pressure Transmitters Needed?

• Filter Monitoring – Detecting blockages or contamination in air filters before performance is compromised

• Airflow Control – Ensuring proper ventilation rates in HVAC and industrial systems

• Fan and Blower Efficiency – Optimizing operation to reduce energy consumption

• Overheating Protection – Detecting airflow loss in cooling systems before critical equipment overheats

• Fire and Safety Systems – Controlling air and fire dampers in compliance with safety regulations

• Heat Exchanger Protection – Anti-freeze monitoring to avoid costly damage in cold conditions
