Piezoresistive level transmitter CS-WPT400

liquid4-20 mAriver

The CS-WPT400 is a submersible level and temperature transmitter designed for continuous measurement from shallow water to deep wells. It provides a standard 4–20 mA output, selectable accuracy (0.5% F.S.L standard, 1.0% option), and IP68 ingress protection. Standard cable material is PE; PUR and FEP are available as options.

Key features

• Silicon-oil filled pressure sensing element suitable for liquid level measurement
• Platinum temperature sensor for accurate temperature monitoring
• Measuring ranges: continuous options from 0–3.5 m H2O to 0–350 m H2O; temperature range −40 °C to 60 °C
• Accuracy: typically 0.5% F.S.L (1.0% F.S.L option)
• Standard output: 4–20 mA
• Electrical connection: cable outlet
• Process connection: submersible design
• Cable: PE standard; PUR or FEP optional
• Ingress protection: IP68 (suitable for immersion to specified depths)

Applications

• Level and temperature monitoring in rivers, lakes and coastal zones
