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-1011 average flow rate probe used for?

The Dwyer PAFS-1011 is used for measuring average flow rate in HVAC systems, particularly for zone control and variable-air-volume terminal units. It detects differential pressure across duct sections, with the H port sensing total pressure and the L port sensing static pressure, making it suitable for industrial process monitoring and control.

What are the specifications of the Dwyer PAFS-1011?

The Dwyer PAFS-1011 has 10 detection points, accommodates 6 mm ID tubing (10 mm OD), and is made of ABS/polycarbonate (UL94-5V). It operates at 4 to 49°C and stores at -40 to +60°C. The probe length is 60.72 cm, and it weighs 28 g. It is designed for air and compatible gas service.

Where to buy the Dwyer PAFS-1011 in Singapore?

You can source the Dwyer PAFS-1011 in Singapore through 3G Electric, an industrial equipment distributor established in 1990. We handle logistics, customs clearance, and delivery to your facility, providing technical support for your HVAC and process control applications.

How to install the Dwyer PAFS-1011 average flow rate probe?

Install the Dwyer PAFS-1011 by mounting it with the integral flange and foam gasket to ensure a seal. Connect 6 mm ID tubing to the push-on connections, ensuring the H port faces total pressure and the L port faces static pressure. Follow standard HVAC duct installation practices for accurate differential pressure measurement.
