The "MGG type" is a magnet-type gearless pressure gauge that is resistant to vibrations and pulsations, allowing for long-term use in harsh environments. The pressure gauges, with an annual production of over 10 million units, display pressure values using gears (amplification mechanisms) rather than Bourdon tubes. During pressure measurement of equipment that generates vibrations, such as pumps, the gears experience significant wear due to vibrations and pulsations, with most failures caused by gear wear. Our product moves the pointer through non-contact magnetic force instead of gears, making it highly resistant to vibrations and pulsations, and exceptionally durable. 【Features】 ■ Resistant to vibrations and pulsations, enabling long-term use in harsh environments ■ Enhanced vibration resistance ■ Maintenance is possible ■ Pricing based on conventional products *For more details, please refer to the PDF materials or feel free to contact us.
