DR3423 HVAC Static Pressure Sensor
DR3423 HVAC static pressure sensor
The DR3423 is a HVAC static pressure sensor with output for building ventilation applications. By Integrating into a building HVAC management system to monitor and control the distribution of warm or cool air through ventilation ducts. With the high accurty sensor, even range low to ± 50Pa, it provides stable measuring result. LCD display is opptional for reading differential pressure on site. In additional, uer can set the pressure range through the built-in dial switch.

FAQ
Why do HAVC need a static pressure sensor?
With the growing requirements of building maintenance, HVAC systems are no longer able to meet demand operating alone. Whether it is a commercial, retail or industrial building, pressure sensors play a significant role in monitoring the building for occupants’ safety and comfort. When integrated with pressure technology, HVAC systems can operate at optimum levels as well as improve building maintenance.
Which applications of static pressure sensors?
Fandesensor static pressure sensors are suitable for applications in HVAC and building automation, clean rooms, hospitals, laboratories, isolation chambers or in the pharmaceutical industry. The highly accurate devices can be employed for all non-flammable and non-aggressive gases. The piezo-resistive pressure sensing element stands out by excellent long-term stability, measures even minimal pressure differences and excludes the risk of cross-contamination.
What is Differential Pressure?
The term “differential pressure” refers to the pressure between two places. Different industries use differential pressure sensors to measure this unique type of pressure. As a application, static pressure sensors are designed to monitor pressure in industrial settings. When measuring and maintaining proper negative or positive pressure, it allows the ventilation system or process airflow system to operate more efficiently and effectively.
