本文提出的真空指示器线路,在抽气系统中当达到需要的真空时,能确保检查和控制同时发信号的真空装置。Φ-210型数字测量仪表稍加改装就可使用。采用ПMT-4M 型压力热电偶式变换器作为压力的一次变换器。真空指示器由变换器热电偶信号放大器、带有执行继电器的比较电路和
The vacuum indicator line presented in this paper ensures that the simultaneous vacuuming of the signal is inspected and controlled when the required vacuum is achieved in the extraction system. Φ-210 type digital measuring instrument can be used after a little modification. Using ПMT-4M pressure thermocouple converter as a pressure converter. Vacuum indicator by the converter thermocouple signal amplifier, with the implementation of the relay comparison circuit and
