Dwyer Air Flow Paddle Switch

Rotating paddle level switches are sensors with an electrical contact output at a specific powder or bulk level.

Dwyer air flow paddle switch.

Time tested in thousands of pipeline installations and processing plants around the world this series is weatherproof designed to meet nema 4 and explosion proof listing included in specifications. The series v4 flotect flow switches are rugged and reliable ideal for automatically protecting equipment and pipeline systems against damage from reduction or loss of flow. Dwyer aafs air flow paddle switch is suitable for use in ducts 8 or over using full stainless steel vane provided. The model aafs adjustable air flow switch is capable of detecting a wide range of air velocities with minimal user calibration.

The models within this category have either top or side mounting. Applications include low air flow condition duct alarm fan monitoring damper feedback air handlers and air flow proving in hvac systems. Applications include natural manufactured or lp gas. Applications include mining silos hoppers food beverage and grain silos.

Air flow proving in hvac systems. The model aafs adjustable air flow switch is capable of detecting a wide range of air velocities with minimal user calibration. This vane is trimmable for smaller ducts. This category contains sensors with an electrical contact output at a specific air flow rate.

The adjustable screw changes the set point at continued. Applications include proof of boiler flow air conditioning controlling of dampers according to flow and protecting pumps motors and other equipment against low or no flow. External adjustment visible dial hermetically sealed snap or mercury switch gas pressure differential pressure switch is used with air and other compatible gases. Dwyer aafs air flow switch is an field adjustable paddle vane switch capable of detecting a wide range of velocities.

Paddle flow switches or vane sensors with an electrical contact output are at a specific flow rate. Ranges from 200 to 1800 fpm stainless steel vane abs housing the model aafs 1 adjustable air flow switch is capable of detecting a wide range of air velocities with minimal user calibration. Quality features include a stainless steel vane galvanized steel base and abs enclosure. Quality features include a stainless steel vane galvanized steel base and abs enclosure.
