The Sonbest SLST1-3 user manual provides specifications, wiring, and usage instructions for the shielded stainless steel package temperature sensor.
The SLST1-3 is a shielded stainless‑steel packaged temperature sensor that incorporates a DS18B20 digital sensor. Its thin 0.15 mm stainless‑steel wall and metal‑pad design give high sensitivity, low thermal lag, and strong anti‑interference performance, while the IP65 rating ensures protection against water and dust.
The sensor uses a 1‑Wire single‑bus interface for easy wiring and supports cable lengths over 100 m. It is suited for harsh environments such as cold storage, pharmaceutical GMP monitoring, telecom rooms, brewing, building automation, and other temperature‑critical applications. The manual details pin definitions, communication protocol, dimensions, and ordering information. This manual is written in Chinese.
