The TA Series is a flexible TA sensor which averages the temperature read across the entire length of the copper tubing, making it ideal for duct temperature measurements. TA Series sensors average the measured temperature across the duct in 6?â?Æ?é?ó?â?ó?ó?é¼?í?é?¼?â?ó?ó?é¼???é?ó, 12?â?Æ?é?ó?â?ó?ó?é¼?í?é?¼?â?ó?ó?é¼???é?ó, or 24?â?Æ?é?ó?â?ó?ó?é¼?í?é?¼?â?ó?ó?é¼???é?ó (1.8 m, 3.6 m, or 7.3 m) lengths. This allows you to cover all your averaging applications with one line.
