NS/NT Electrode Level Detectors

Galvatek’s NS/NT electrode level detectors offer a reliable and precise solution for regulating and monitoring liquid levels in industrial tanks. Based on the principle of electrical conductivity, these passive sensors are ideal for demanding environments where process precision and safety are paramount. Given that these devices are entirely passive, the use of suitable electronic controllers (type ETS or ENR) is essential.

Data sheet – NS/NT level switches Accessories

Operating principle: Based on electrical conductivity (≥ 10 µS).
Number of electrodes: 2 to 5 electrodes to detect up to 4 levels.
Available materials:
- Stainless steel, titanium or PTFE Compound electrodes for optimum chemical resistance.
- Connection boxes in PP or PVDF (IP65).
Compatibility: For use with process electronics (ETS100, ETS200, ETS410 and ENR300)
Maximum temperature:
- Up to 100°C for PTFE Compound electrodes.
- Up to 90°C for titanium or stainless steel electrodes.

Increased accuracy: Reliable detection of high, low and intermediate thresholds.
Flexibility: electrodes can be cut to length on site (except for PTFE Compound electrodes).
Chemical resistance: Robust materials for corrosive environments.
Easy installation: various mounting options with compatible accessories.
Reliability: Robust design minimizes interference and risk of failure.

Chemical industry: level control in corrosive or aggressive solutions.
Water treatment: Tank monitoring to prevent overflowing or running dry.
Food industry: Precise detection in sensitive processes.
Metal vessels: Ground electrode can be connected directly to the vessel.

Protection standard: IP65 splash-proof enclosure (EN 60529).
Anti-fouling design: Minimum distances between electrodes to avoid deposits.
Process safety: prevention of overflows and protection of equipment (pumps, heaters).
