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 measuring instrument for vacuum degree , on the market at present most of the thermocouple vacuum gauge is a thermocouple gauge corresponds to a vacuum gauge. Although there are numerical display, but only the switch quantity output, without output of real-time data, not making convenience for secondary development and utilization. Multi-chan-nel thermocouple vacuum gauge can simultaneously process 8-way thermocouple gauge signals , and output data through the RS232, which can more intuitively observe the change of vacuum degree. At the same time it have overload protection function, when the measured pressure beyond the range of thermocouple gauge , the constant current source is automatically cut off to pro-tect the thermocouple gauge. In the process of using it not only saves space, reduces the test cost, but also reduces the compli-cated wiring.
