Multi-application Guided Wave Radar Level Transmitters

INSTROTECH offers Kobold’s NGR, a robust, maintenance-free level sensor that uses TDR technology (time domain reflectometry) for the precise level measurement and monitoring of oil- and water- based liquids, grinding and hydraulic oils as well as mixtures with cleaning, degreasing and care products.  The NGR can also work in deposit-forming and foaming liquids.

The NGR’s guided radar uses time-off-light technology to measure electromagnetic pulses. The time difference between the sent pulse and the reflected pulse is used to calculate the level, both as a continuous value (analogue output) and a free position switching point (switching output).

The flexible probe can be changed or cut, allowing the sensor to be integrated quickly into any application. The NGR sensor’s intuitive setup uses four buttons and a display to ensure quick and easy adaptation to the application.

The NGR operates on a modular sensor concept, adaptable for every application and suitable for almost every liquid.  The measuring principle is independent of the medium’s density, temperature, pressure, humidity and conductivity.
