VEGA的優(yōu)點主要表現(xiàn)為：
采用非接觸式測量，不受介質特性影響（高溫、高壓、真空、粉塵、蒸汽及測量腐蝕性*或混合度高的介質）；可測量液體或固體介質，且混合或更換介質對于測量結果都沒有影響，也不需要重新調試儀表；由于采用非接觸式測量，VEGASON的維護保養(yǎng)非常簡單。 多年來，德國VEGA為冶金、礦產、建材、石化、能源、電力、化工、水處理、食品、醫(yī)藥、造紙、造船、機械制造等領域提供了優(yōu)質的產品和服務。

measuring cell
Area of application
The VEGABAR 66 is a suspension pressure transmitter for level measure-ment in wells, basins and open vessels. Its great flexibility through differ-ent cable and tube versions allows VEGABAR 66 to be used in many
different applications.
Advantages
• High plant availability through maximum overload and vacuum resist-ance of the ceramic measuring cell
• Self-cleaning effect thanks to front-flush design
• Low costs for maintenance thanks to wear-free ceramic measuring cell
Function
The heart of the pressure transmitter is the pressure measuring cell that
transforms pressure into an electrical signal. This pressure-dependent
signal is converted into a standard output signal by the integrated
electronics.
The sensor element is the CERTEC
measuring cell with excellent long-term stability and high overload resistance. The CERTEC
®
measuring
is also equipped with a temperature sensor. The temperature value can
be displayed via the indicating and adjustment module or processed via
the signal output.
