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.

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-1002 average flow probe used for?

The Dwyer PAFS-1002 average flow probe measures differential pressure in HVAC systems, specifically for zone control and variable-air-volume terminal units. It detects total and static pressure through its H and L ports, making it suitable for air and compatible gas flow measurement in industrial piping.

What are the specifications of the Dwyer PAFS-1002?

The Dwyer PAFS-1002 has an ABS/polycarbonate body rated UL94-5V, with 4 detection points and a length of 8.02 cm. It uses a 6 mm ID, 10 mm OD tubing connection and an integral flange with gasket. Operating temperature is 4 to 49°C; storage is -40 to +60°C. Weight is 28 g.

Where to buy the Dwyer PAFS-1002 in Singapore?

3G Electric supplies the Dwyer PAFS-1002 average flow probe to Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact our team for a quote and lead time on this measurement device.

How to install the Dwyer PAFS-1002 average flow probe?

Install the Dwyer PAFS-1002 using its integral flange with foam gasket, securing it to the duct or pipe. Connect 6 mm ID tubing to the push-on ports: the H port for total pressure and L port for static pressure. Ensure the probe is positioned perpendicular to flow for accurate differential pressure readings.
