The PTS23 temperature sensor was specifically designed for temperature applications in residential and commercial spas, pools, and solar systems. The overmolded glass encapsulated NTC allows for protection against water ingress that cause traditional temperature sensors to fail. The low cost semi-automated united states manufacturing process allows for a cost effective solution.
