Good for air-quality applications
Überblick
Der 43347 ist ein hochpräzieser RTD, der oft zur Messung von Temperaturgradienten oder in Luftqualitätsmessungen verwendet wird. Zur Vermeidung von Fehlern durch Sonneneinstrahlung wird er oft in den 43502 ventilierten Strahlungsschutz eingebaut.

Technische Beschreibung
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.

Additional Compatibility Information
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.
