Model VA1000 MOPAN industrial pressure gauges are used throughout the process and industrial markets. The gauges use diaphragms as pressure sensors that have excellent resistance to pressure pulsation, vibration, and shock to prevent needle pointer fluctuation or even gauge damaged. No need to fill oil in the gauge. No need to fill oil in the gauge and the performance of the gauge is as good as the oil filled one.
◇ Resistance to Pulsation
◇ Resistance to Vibration ◇ Medical Equipments
◇ Suction Machines
The diaphragm pressure gauges have been widely used in the harsh environments. The architecture of the diaphragm pressure gauge is much simple, compared other sensor types such as Bourdon tube and bellow pressure sensor, and simple means reliable. That’s why the diaphragm pressure gauge have many features that you concern but Bourdon tube and bellow sensor cannot meet. The diaphragm pressure gauge has great resistance to pressure pulsation and vibration. Users don’t break the gauges as measuring unstable pressure source which pulsation might occur, besides, the fluctuation of the dial pointer caused by unstable pressure source or mechanical vibration will not happen. The 2017 patented design, diaphragm + piston sensor, use a piston to transmit pressure which can protect the diaphragm from 200% exceeded pressure.
The key components of the diaphragm gauge are an elastic diaphragm and a screw. As the measuring pressure deform the elastic diaphragm, the screw transforms deformation into the spiral movement of the dial pointer. Sound simple, but making a diaphragm with good mechanical properties is difficult! That’s why other pressure gauge companies still produce Bourdon tube gauges for you.
The pressure sensing mechanism of a Bourdon tube is complex and not straightforward. The connection from the tube to the dial pointer is made by many small components like gears. That makes pressure gauges as weak as mechanical clocks. Your Bourdon tube pressure gauges supplier might tell you that pressure gauges are precision instruments so that you have to protect them carefully. If you use your Bourdon tube pressure gauges to measure an unstable pressure source and break your gauges, the supplier might tell you that you are using the gauges in an improper way. However, that was preventable by choosing MOPAN’s diaphragm pressure gauges.
The tire gauges use a diaphragm as a sensor that has been recognized by many world-class companies have become the Harley-Davidson official authorized accessories and are used by many vehicle companies, such as BMW.
*This feature guarantee the gauge can bear 200% of the full-scale pressure without any damage and only support for the 2017 new patented 'diaphragm + piston' sensor type pressure gauge.
MOPAN Co., Ltd., founded in 2014, focuses on designing and manufacturing of diaphragm pressure gauges. Chia-Hsin Lee, the inventor of the world first elastic diaphragm pressure sensor in the 70s, leads MOPAN’s development team with his 30 years of experiences. The new generation patented robust diaphragm sensors with isolated technologies that are capable of measuring ultra-high and ultra-low pressure precisely with extremely durable structure. We keep investing more resources on product improvement and quality control. Our goal is providing the top quality and services for our customers in different industries.
MOPAN’s next generation pressure gauges use a completely different design from the traditional Bourdon tube. It benefits in durability in all kinds of harsh environments, reliability for long-term usage, and precision in all ranges of pressure. The patented new design gauges feature Resistance to Pulsation, Anti-explosion, and Auto-sealing for better safety and reliability. MOPAN is always the leading company that provides the most advanced products and superior quality for customers.
