Regarding the STT-26 submersible temperature transmitter, it is designed to meet your technical requirements for installation in a pond. While it does not come with a specific bracket or anchor, it can be laid directly on the base of the pond using its own weight or suspended by its cable. If there is turbulence present, some users opt to deploy a perforated stilling tube to ensure stability.
Additionally, we offer a variation of the STT-26 that features a temperature probe tip and a parallel 1/4″ thread on the front. This version can be threaded into an underwater pipe for your specific application. Please let us know if you require further assistance or have any additional questions.
