43347-L RTD Temperature Probe

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 43502 attaches to the legs of a UT20 or UT30 tower via a CM202, CM203, CM204, or CM206 crossarm. Two CM210s can be used to attach the crossarm to two tower legs.) 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.
