真空计是测量真空度的仪器,目前市场上大多数热偶规真空计都是一个热偶规对应一个真空计,虽然有数值显示,但只有开关量的输出,没有实时数据的输出,不方便二次开发和利用。多通道热偶规真空计可以同时对8路热偶规的信号做出处理,并且通过RS232将数据输出,可以更加直观的观察到真空度的变化。同时具有过载保护功能,当被测压力超出热偶规的量程时会自动切断恒流源对热偶规管进行保护。在使用的过程中不仅节省了空间,降低了测试成本,而且减少了复杂的布线。
Vacuum gauge is a measure of the degree of vacuum instruments, the current market most of the thermocouple gauge vacuum gauge is a thermometer corresponding to a vacuum gauge, although the numerical display, but only the switch output, there is no real-time data output, inconvenient Secondary development and utilization. The multi-channel thermocouple gauge can simultaneously process the signals of the 8-way thermocouple and output the data through the RS232, so that the change of the degree of vacuum can be observed more intuitively. At the same time with overload protection, when the measured pressure exceeds the thermocouple gauge range will automatically cut off the constant current source on the thermocouple regulatory protection. In the process of using not only save space, reduce test costs, but also reduce the complexity of wiring.
