RA-1250 Thermal Dispersion Fan Inlet Sensors Airflow Measuring System
Averages velocity and temperature from fan inlet sensors in a duct or plenum
Taking fan airflow measurement to the next level, our RA-1250 features low profile air flow sensors, a transmitter with a digital display, very high accuracy, and shielded CAT5e communication cables to reduce time spent on installation and commissioning. Aerodynamic fan inlet sensors improve fan speed while reducing power consumption, and traceable calibration allows for accurate, repeatable measurement from zero to maximum airflow using our advanced thermal dispersion measurement technology.
Features and Benefits
Resources
- Aerodynamically Shaped, Surface Mount Fan Inlet Sensors – Provide nominal fan performance degradation, improves fan speed, and reduces power consumption in comparison with other fan inlet devices.
- Multiple-Pivot Hinge Design – Allows fan inlet sensor to conform to the shape of the inlet bell.
National Institute of Standards and Technology (NIST) Traceable Calibration at Each Sensing Point – Provides documented calibration values - LCD Screen on DMPR-RA003 Electronic Controller – Provides visual readout of flow, temperature, and diagnostics
- CAT5e Cable with RJ-45 Connectors – Reduces installation and commissioning time; Allows for field repair
- NIST Traceable Calibration – Allows accurate, repeatable measurement from zero to maximum airflow using Johnson Controls® thermal dispersion measurement technology
