Datasheet Content

Sonde de débit moyen

Idéal pour la mesure de débit de ventilation

La Série PAFS-1000 Sonde de Debit Moyen est indiquée pour détecter une pression
différentielle dans la section d’entiée d’unités terminales a volume d’cit variable et d’unités
terminales de ventilation. Les appareils peuvent également étre utilisés pour détecter la
pression différentielle en d‘autres endroits des systémes de conduite principaux et secondaires.
Le port “H” détecte la pression totale tandis que le port “L” détecte la pression statique. La
différence entre ces signaux correspond au différentiel, ou pression dynamique.

Product Description

The Dwyer PAFS-1005 is an average flow probe designed for HVAC zone control applications. It features four detection points across a 25.26 cm length and accommodates 6 mm ID tubing. Built from ABS/polycarbonate UL94-5V material, it operates reliably between 4–49°C and fits standard ductwork measurement installations.

Frequently Asked Questions

What is the Dwyer PAFS-1005 average flow probe used for?

The Dwyer PAFS-1005 is used for HVAC zone control applications to measure differential pressure in variable-air-volume terminal units and ductwork. It detects total pressure at the H port and static pressure at the L port, with four detection points across a 25.26 cm probe length for accurate airflow measurement.

What are the specifications of the Dwyer PAFS-1005?

The Dwyer PAFS-1005 has a probe length of 25.26 cm with four detection points. It is made of ABS/polycarbonate UL94-5V material, operates at 4 to 49 °C, and accommodates 6 mm ID tubing. It weighs 28 g and is designed for air and compatible gas service in HVAC systems.
