Duct mounted air flow sensor.

Ideally suited for new installations or retrofit applications requiring accurate flow measurement in pipes or small duct locations having limited straight duct runs. Used with any sensaphone that will accept a 4 20ma input signal the device will provide real time data. Ebtron s thermal dispersion airflow measurement products provide accurate repeatable and reliable solutions for today s high performance buildings. Monitor air flow in duct work.

The historically reliable rheotherm flow meter for duct flow measurement is available with a revolutionary sensor head which eliminates off axis error common to other sensors. It will cause your sensaphone to activate an alarm when the airflow reaches a set threshold. Silicon chip design is created from thin film thermally isolated bridge structure containing both heater and temperature sensing elements. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans.

All airflow sensors operate on heat transfer flow and differential pressure. The system measures true mass flow rate in turbulent ducts and pipes using our standard gas flow probe design with the rheovec sensor head added. An air switch senses positive negative or differential air pressure and actuates an internal switch. Volu probe fi ss fan inlet airflow traverse probes.

Free shipping by amazon. This air flow transmitter registers the airflow speed according to a thermal principle based on the fact that the cooling action of air increases with airspeed. Belimo offers a broad range of air duct sensors covering all standard measurement values. Tjernlund ps1503 duct airstat pressure switch.

Get it as soon as wed sep 30. 3 6 out of 5 stars 9. Air stream sampling is accomplished by sampling tubes that penetrate and traverse either the supply or return air ducts. A set of two offset mounted traverse probes each with multiple sensors formulated on a concentric area basis.

Series pafs 1000 ideal for sensing fan flow rates averaging flow sensor is ideal for sensing differential pressure in the inlet section of variable air volume terminal units and fan terminal units. Duct mounted airflow measurement station is easy to install and utilizes an airflow averaging element. The nfpa recommended sensing technology for externally mounted duct smoke detector enclosure is photoelectric type smoke sensor. This provides rapid response to the air or gas flow and amount and direction delivering a proportional output voltage.
