Duct Mounted Air Flow Sensor

Tjernlund ps1503 duct airstat pressure switch.

Duct mounted air flow sensor.

4 2 out of 5 stars 251. An air switch senses positive negative or differential air pressure and actuates an internal switch. 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. 3 6 out of 5 stars 9.

Ebtron s thermal dispersion airflow measurement products provide accurate repeatable and reliable solutions for today s high performance buildings. Get it as soon as wed sep 30. 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. Temperature humidity dew point co voc s pressure and low temperature limit detection.

Ideally suited for new installations or retrofit applications requiring accurate flow measurement in pipes or small duct locations having limited straight duct runs. Air stream sampling is accomplished by sampling tubes that penetrate and traverse either the supply or return air ducts. Rely on grainger for a wide range of duct pressure switch options. All airflow sensors operate on heat transfer flow and differential pressure.

The nfpa recommended sensing technology for externally mounted duct smoke detector enclosure is photoelectric type smoke sensor. More buying choices 20 93 14 new offers tpi rh3a series rh adjustable air flow differential pressure switch control 0 05 12 wc compression connection. It will cause your sensaphone to activate an alarm when the airflow reaches a set threshold. 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.

A set of two offset mounted traverse probes each with multiple sensors formulated on a concentric area basis. Monitor air flow in duct work. This provides rapid response to the air or gas flow and amount and direction delivering a proportional output voltage. Duct mounted airflow measurement station is easy to install and utilizes an airflow averaging element.

Used with any sensaphone that will accept a 4 20ma input signal the device will provide real time data. Belimo offers a broad range of air duct sensors covering all standard measurement values. Volu probe fi ss fan inlet airflow traverse probes. Silicon chip design is created from thin film thermally isolated bridge structure containing both heater and temperature sensing elements.
