Good for air-quality applications
Resumen
The 43347-L, manufactured by R. M. Young, is a highly accurate RTD that often provides delta temperature measurements for air quality applications. Typically, it is housed in the 43502 fan-aspirated radiation shield, which greatly reduces radiation errors.

Descripción detallada
To determine delta temperature, a 43347 probe mounted in a 43502 shield is attached to the mast of a UT20 or UT30 tower, while another 43347 probe mounted in a 43502 shield is attached to the tower at a 2-m height. The temperature difference of the two measurement heights is calculated and used to determine atmospheric stability as required by the EPA.
The 43347 may also be housed in a 41003-5 Naturally Aspirated Shield if fan-driven aspiration is not required. Additional hardware is required (see Ordering Info and Compatibility).
The standard 43347 probe has an RTD uncertainty of ±0.3°C. If increased accuracy is required, a three point calibration can be ordered that allows the RTD to have an uncertainty of only ±0.1°C.

Mounting
The 43347 is typically housed in a 43502 Aspirated Radiation Shield to provide delta-temperature measurements for air quality applications. Delta temperature measurements use two 43502s attached at different heights.
The 41003-5 naturally aspirated radiation shield can serve as an alternative to the 43502 if a fan-driven aspiration shield is not required. The 27251 split nut plug must be used.
Both the 43502 and 41003-5 can be attached to either a mast or crossarm.
Data Logger Considerations
The 43347 comes in two versions—the "IX" version and the "VX" version. The "IX" version connects to a current excitation channel; only the CR3000 and CR5000 are compatible with the -IX.
The "VX" version connects directly to voltage excitation channels. All compatible data loggers can use the VX version.
