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.

Pour les modéles de PAFS-1002 @ PAFS-1005, jusqu’d quatte points de détection et des
longueurs de 8.02 4 25.26 cm sont disponibles pour adapter le diamtre de Ia boite de 10.16

Product Description

Frequently Asked Questions

What is the Dwyer PAFS-1003 average flow probe used for?

The Dwyer PAFS-1003 average flow probe is used for measuring differential pressure in HVAC zone control, variable-air-volume terminal units, and ventilation duct systems. It detects total pressure on the H port and static pressure on the L port, providing dynamic pressure readings for process monitoring and flow verification.

What are the specifications of the Dwyer PAFS-1003?

The Dwyer PAFS-1003 has four detection points, a length of 13.73 cm, and is made of ABS/polycarbonate rated UL94-5V. It accommodates 6 mm ID, 10 mm OD tubing, operates from 4 to 49 °C, and stores from -40 to +60 °C. Weight is 28 g. Service is for air and compatible gases.

Where to buy the Dwyer PAFS-1003 in Singapore?

3G Electric supplies the Dwyer PAFS-1003 average flow probe to Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time. As a sourcing partner, we provide technical support for HVAC and process applications.

How to install the Dwyer PAFS-1003 average flow probe?

Install the Dwyer PAFS-1003 by mounting it with the integral flange and foam gasket. Connect 6 mm ID, 10 mm OD tubing to the push-on connections. Ensure the H port faces total pressure and the L port faces static pressure. Follow Dwyer's guidelines for duct insertion and sealing to avoid leaks.
