The SPT21WS1 is a fully sealed submersible level transmitter designed specifically for corrosive chemical applications and low‑range level measurement. It uses a chemically inert PTFE housing with a ceramic capacitive pressure sensor and a high‑precision signal conditioning circuit. The integrated construction, IP68 protection, and corrosion‑resistant materials allow long‑term immersion in aggressive liquids. Multiple output options—including 4–20 mA, voltage, and RS485—provide flexibility for industrial control systems.

The key features are:

• Designed for corrosive and chemically aggressive liquids
• PTFE housing with ceramic diaphragm for maximum chemical resistance
• Fully sealed IP68 construction for long‑term submersion
• High stability and reliability with ±0.5% FS accuracy
• Low measurement ranges available (0–1 to 0–5m H₂O)
• Multiple output options: 4–20 mA, 0–5 V, 0–10 V, RS485
• Operating temperature up to 80°C
• Overpressure protection: 2x full scale

Delivery time for non-stocked configurations is typically 4–6 weeks.
