New warren g-v ls-5055 ls series airflow sensor
LS Airflow Sensors are cooling effect monitors that provide a positive indication of the presence of airflow. Independent of the air temperature, these units are used to operate an alarm or shutdown device when airflow drops below a preset level.
* Small size meets MIL Shock/Vibration/Ambient requirements
* Operates down to -55 C if continually energized
* High reliability/enhance4d MTBF rate
* Self-contained Sensor/Switch, no additional circuitry required
* Built-in time delay ignores transient airflow losses
* Computer/peripheral systems
* MIL communications systems
LS Airflow Sensors utilize a differential expansion principle in which the air entering the inlet circulates and cools an electrically heated internal element. Varied voltage source designs available. When the airflow drops below the nominal setting, the temperature of the heated element rises quickly, causing the operation of a contact (either N.O. or N.C.). This inherent thermal delay avoids contact operation on brief interruptions of airflow. On restoration of airflow, the sensor will automatically reset after a brief cooling period.
5 V., 12 V., 28 V., or 115 VAC/DC

1 to 20 seconds (depending on setting and air velocity prior to stoppage)
