Air Flow Transducer
ESF-35-2:
ESF is an airflow transducer with a broad application area. It can be used
for control, surveillance, and regulation of the flow rate in fresh-air
and ventilation systems, etc.
Features:
- Converts airspeed into a 4 – 20mA or a 0 – 10 VDC signal
- Linear output signal
- Fully electronic registration of airflow
- AC or DC voltage supply
- Compensates for changes of air temperature
- Telescopic sensor facilitates installation
- Temperature output signal 0 – 10 VDC
- Fuse Protected
- Made with corrosion resistant material
Applications:
The ESF-35-2 airflow transducer can be used in a wide range of applications such as:
- Measurements of airflow speed via PLC/outstation/EMS
- Regulation of airflow speed
- Monitoring of airflow speed
Installation:
The airflow transducer ESF-35-2 is installed in such a way that the current
of air passes through the gap of the sensor head. Conductors to and
from the transducer should be kept isolated from high-power conductors
where powerful transient voltage spikes may appear.
Functions:
The ESF-35-2 transducer registers the airflow speed according to a thermal
principle based on the fact that the cooling action of air increases
with airspeed. The action is measured and converted to a 4 – 20mA or a 0
– 10 V signal corresponding to airflow speeds from 0 – 8 m/s (0 – 1575
ft/min) or 0 – 16 m/s (0 – 3150 ft/min).
