Rosemount Stainless Steel Multifunction Watertight Temperature Switch
This multifunction temperature switch is housed in a rugged 316L stainless steel enclosure, designed specifically for harsh environments where water and corrosion resistance are mandatory. Its straightforward design allows for quick field wiring and installation, while the internal mechanism provides highly repeatable performance for years of service.
With a wide temperature range of -40°F to 750°F, this switch is an excellent choice for critical temperature control, emergency shutdowns, or alarm systems.
