RBF-570復合變送器
簡介
RBF-570設計用于1×10-9 mbar…1000 mbar壓力范圍內氣體的真空測量,該量規由兩個獨立的測量系統組成(Pirani和冷陰極系統(基于反向磁控管原理))。冷陰極測量電路由Pirani電路控制,在壓力P<1×10-3mbar時激活。若冷陰極測量電路未被點燃,則輸出皮拉尼的測量值作為測量信號。在整個測量范圍內,測量信號作為壓力的對數輸出。
The RBF-570 is designed for vacuum measurement of gases in the pressure range 1 x 10-9 mbar...1000 mbar and consists of two independent measuring systems (Pirani and cold cathode system (based on the reverse magnetron principle)).The cold cathode measurement circuit is controlled by the Pirani circuit and is activated at pressures P < 1 x 10-3 mbar. If the cold cathode measurement circuit is not fired, the measured value of the Pirani is output as a measurement signal. The measurement signal is output as the logarithm of the pressure over the entire measurement range.
