NRF - Capacitance Level Transmitter

Brand: KOBOLD Instruments, Inc.

The KOBOLD NRF capacitance level transmitter is designed to measure water-based liquids or oils in metal tanks.

The probe measures level by measuring the change in capacitance as level changes in the tank.

The transmitter’s microprocessor-based electronics convert this minute capacitance change into a linear, highly accurate 4-20 mA, loop-powered signal.

The compact, microprocessor-based design makes installation and set up a simple task.

Advanced signal conditioning circuitry greatly minimizes the adverse effects of coating media.

The NRF Series capacitance level transmitter is available in rigid and flexible probe versions.

An NPT threaded fitting and Tri-Clamp® sanitary fittings are available as standard items.

The standard probes for conductive media are PFA-clad to stand up to aggressive media.

The NRF is truly designed with tough applications in mind.

Alternate versions of the NRF, such as high-sensitivity units for non-conductive fuels and oils, are also available.
