Lightning Protection For Radar Level Gauges: A Key To Ensuring Stable Equipment Operation

As industrial automation continues to advance, the Smart Instruments industry is rapidly developing. However, many Smart Instruments and Meters contain numerous microelectronic components, often suffering from insufficient insulation strength. Therefore, during the rainy season, lightning protection for smart instruments becomes especially important to avoid significant losses. Below, we will explore some effective measures for Lightning Protection for Radar Level Gauges.

1.Importance of Grounding for Lightning Protection: The housing of the radar level gauge should be connected to devices such as control cabinets, dedicated control consoles, and power cabinets, ensuring that the housing is adjacent to ordinary flat steel materials. The power supply of the instrument (e.g., the negative terminal of the 24V supply) should be connected to the grounding of the instrument and the input/output grounding of the accumulator to form an equipotential reference. Additionally, the grounding of intrinsically safe circuits, safety barriers, suppressor barriers, and other safety devices should also be considered for equipotential bonding with the reference point of the instrument.

2. Power supply lightning protection measures: The power supply Lightning protection for radar level gauges of Smart Instruments and Meters cannot be ignored. Radar level meters should be equipped with surge protection devices to ensure that the instrument is not affected by surges exceeding the withstand voltage limit. Surge attenuate can effectively guide the induced lightning surge current to the ground during thunderstorms.

3.Trust Channel Surge Devices: For smart instruments equipped with trust channel surge protection, it is essential to ensure they possess accurate, stable, and flexible dynamic transmission capabilities. Additionally, during thunderstorms, these devices should effectively release over-voltage surges to the ground to ensure the safety of transmission.

4.Regular Inspection and Maintenance: Lightning protection for radar level gauges should involve regular checks and maintenance of the power grounding, bus-bars, grounding bodies, surge protectors, and power supply lightning protection devices of smart instruments. Necessary replacements should be made promptly to ensure that the equipment remains in good condition at all times.
