NGR Guided Radar Level Transmitter

Brand: KOBOLD Instruments, Inc.

The NGR is a level sensor that uses TDR technology (time domain reflectometry) and thus can be used in oil and water based liquids without calibration. The NGR's guided radar uses time-offlight 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 (Analog output) and a freely positional switching point (switching output). Due to its flexible probe that can be changed or cut, it is possible to integrate the sensor quickly into any application.

The NGR can work in deposit-forming and foaming liquids. The sensor's intuitive setup uses four buttons and a display to ensure quick and easy adaptation to the application.
