Since over 200 years ago, Bourton Tube is used as the pressure sensor, it links gear that amplifies the rotation of an indicator forms the pressure gauge. Due to the nature of innate structure, it is vulnerable and has limited pressure range. After the researches and improvements for so many years, (e. g., Oil-Filled type, Interface Diaphragm type, etc. ) the performances are getting much better. However, still, the products can&＃39;t fulfill the requirements on very low pressure, very high pressure, vibration resistance, shock resistance, suddenly pulse, and self-sealing, etc.To solve the mentioned disadvantages, this Innovative Series use an elastic diaphragm as the sensor, use a spiral rotating indicator to form the Pressure Gauges that has stable, excellent vibration resistance and high accuracy characteristics.The supplementary invention of Pressure Transformation makes high pressure gauge for best vibration proof, high accuracy and self-sealing to high pressure, it&＃39;s excellent use for hydraulic devices application.This Pressure Transformation invention can be combined with various pressure transducers (e. g., Bourton Tube, Electronic Digital type, etc. ) to establish pressure gauges with wide pressure ranges (micro, low, middle, high, or excellent high pressure).After many year research and development, the Innovative Series should be able to replace the main stream of pressure gauges that use traditional Bourton Tubes.Welcome the cooperation from any company who is interested in the opportunities of promoting Innovative Series products to the global market.
