NGM - Guided Wave Radar Level Transmitter

Product Description

The KOBOLD NGM Series guided wave radar level transmitter uses time domain reflectometry (TDR) technology, also known as “guided microwave” or “guided wave radar". This means that low-energy and high-frequency electromagnetic impulses, generated by the sensor’s circuitry, are propagated along the probe, which is immersed in the liquid or solid to be measured. When these impulses hit the surface of the media, part of the impulse energy is reflected back up the probe to the circuitry, which then calculates level from the time difference between the impulses sent and the impulses reflected. The KOBOLD NGM Series guided wave radar level transmitter’s sensor can transmit the media level as a 4-20 mA analog output, or it can convert the values into a freely programmable switching output signal.
