Conductive level switch NS/NT

for waterfor liquidsfor corrosive liquids

Product overview: Galvatek’s NS/NT electrode level detectors provide a precise, passive solution for monitoring and controlling liquid levels in industrial tanks. They detect level by electrical conductivity and require compatible process electronics (ETS100, ETS200, ETS410 or ENR300) for operation.

Key benefits:

• Reliable level detection of high, low and intermediate thresholds.
• On-site adaptability: electrodes can be cut to length except for PTFE Compound variants.
• Chemical resistance: choice of stainless steel, titanium or PTFE Compound for aggressive media.
• Multiple mounting options and compatible accessories for straightforward installation.
• Design reducing interference and minimizing operational failures.

Main applications:

• Chemical industry: level control in corrosive or aggressive solutions.
• Water treatment: tank monitoring to prevent overflow or dry running.
• Food industry: precise level detection in sensitive processes.
• Metal tanks: ground electrode can be connected directly to the vessel.

Safety and compliance:

• Protection rating: IP65 splash-proof enclosure (EN 60529).
• Anti-fouling design: minimum spacing between electrodes to limit deposits.
• Process safety: prevents overflows and protects equipment such as pumps and heaters.

Options and accessories:

• Assembly Key SB for BC head (universal key).
• SL Mounting Key for LC head (for opening LC terminal box and cable gland).
• LC Terminal Box (PP red head or PVDF white head).
• BC Terminal Box (PP red head or PVDF white head).
• HM Mounting Sleeve for BC head (EPDM, bore diameter 70–76 mm, for high-temperature liquids).
• ML Mounting Sleeve for LC head (EPDM, bore diameter 63 mm, for confined spaces).
• EM Mounting Sleeve for BC head (EPDM, bore diameter 87–90 mm, reduced footprint installation).
• HL Support for LC head (fixed by screws on tank rim, for LC head).
• HB Support for BC head (fixed by screws on tank rim, for immersion tube length ≤ 800 mm).

Technical specifications:

• Operating principle: Based on electrical conductivity (≥ 10 µS).
