The water circuit of a coffee machine has limited space and experiences significant temperature fluctuations, so probe installation is not simply a matter of "installing wherever there is a hole." This article explains the selection and installation boundaries for TFE-1-A1, TFE-304-M6 and F9027 from seven practical checkpoints: space, temperature, cleaning, sealing, wiring harness, flow regime and maintenance access.
