Guided Wave Radar Level Transmitter: Made in the USA

The KOBOLD NGR guided wave radar level transmitter exemplifies American manufacturing excellence with its robust construction and innovative design. Built to exacting standards in US facilities, the NGR combines precision engineering with practical features like field-adjustable probe lengths and an intuitive user interface. This domestic manufacturing approach ensures superior quality control and provides customers with responsive technical support and quick delivery times for their level measurement needs.

Easy Integration into Existing or New PLC Systems

The NGR guided wave radar level transmitter features a versatile output system that combines both 4-20mA analog and transistor switching signals, allowing for straightforward integration with PLC systems. The analog output, compliant with NAMUR NE 43 standards, connects directly to PLC analog input cards, while the switching output provides additional control options through digital inputs. The integral display enables easy setup and verification of PLC communications, eliminating the need for additional configuration tools or software.

Choosing Between the NGM and the NGR Guided Wave Radar Level Transmitters
