Fits washdown and corrosive temperature alarm/control where you need an Ashcroft GT (G-Series) temperature switch—ranges from about −40 °F to 750 °F, ±1% of span repeatability, and a 316L stainless NEMA 4X / IP66 enclosure with direct or remote thermal systems.
Key advantages
- Ranges — About −40 °F to 750 °F
- Repeatability — ±1% of span
- Enclosure — 316L SS NEMA 4X / IP66
- Setpoint — Single or dual; fixed or adjustable deadband
- Mount — Direct stem or remote capillary 5–25 ft
Typical applications
- Process temperature trips.
- Washdown equipment interlocks.
- Boiler / burner high-temp alarms.
Selection guide
- GTS / GTA / GTD function
- Direct vs remote
- Stem / capillary length
Common mistakes
- Aluminum LT ordered for stainless requirement.
- Capillary too short for remote mount.
- Wrong switch element electrical rating.
