43347-L RTD Temperature Probe

THÔNG TIN SẢN PHẨM

Overview

The 43347-L, manufactured by R. M. Young, is a highly accurate RTD that often provides delta temperature measurements for air-quality applications. To greatly reduce radiation errors, house your 43347-L in a 43502 fan-aspirated radiation shield.

Benefits and Features

Uses 1000 Ω RTD for highly accurate air temperature measurements
Well-suited for air-quality applications
43502 fan-aspirated radiation shield reduces radiation errors for more accurate measurements
Ideal for delta temperature measurements used in calculating atmospheric stability class

Detailed Description

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.
