RBF-570复合变送器
简介
RBF-570设计用于1×10-9 mbar…1000 mbar压力范围内气体的真空测量,该量规由两个独立的测量系统组成(Pirani和冷阴极系统(基于反向磁控管原理))。冷阴极测量电路由Pirani电路控制,在压力P<1×10-3mbar时激活。若冷阴极测量电路未被点燃,则输出皮拉尼的测量值作为测量信号。在整个测量范围内,测量信号作为压力的对数输出。
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.
