NMC

Product catalog summary

Overview: The document provides technical specifications and details for the KOBOLD capacitive level meters, specifically the NMC model, designed for measuring liquid levels in tanks. These devices are suitable for various applications, including water, liquid food, chemicals, oils, and pharmaceuticals.

Specifications:

Probe lengths range from 265 mm to 4000 mm, with a measuring error of less than 1.5% of the probe length.
Maximum pressure is 30 bar at 20°C and 10 bar at 90°C.
Medium temperature can reach up to 90°C, with a special model (NMC-H) allowing up to 125°C.
Materials include polycarbonate housing and stainless steel or PVDF for connections and probes.
Electrical output is 4-20 mA, 2-wire, with a supply voltage of 10-35 VDC (12-30 VDC for ATEX).
Protection rating is IP 65, and the device is ATEX certified for hazardous environments.

Design and Functionality:

The level meters use a capacitive measuring principle, where the probe and tank wall form a capacitor, with the liquid acting as the dielectric.
Changes in capacity due to liquid level variations are converted into a percentage display or a 4-20 mA signal.
Different probe configurations are available for standard applications, non-metallic tanks, aggressive media, and high-temperature environments.

Applications: The NMC model is versatile, suitable for measuring levels in water, liquid food, chemical and aggressive liquids, oil, and pharmaceutical liquids.

Installation and Maintenance:

The device features a plug-in evaluation module for easy maintenance and replacement.
Mechanical connections include G 1 male and G 2 male threads, with adapters available for specific installation requirements.

Ordering Information: The document provides a detailed guide on ordering, specifying probe length, mechanical connection, ATEX compliance, and supply voltage options.
