Technical Details RoHS certificate: Accuracy of sensor element1): Repeatability: Resolution: Response time: Dielectric constant: Conductivity: Max. level change: Inactive area at probe end1): 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 (analogue output) and a freely positionable...
