MEASALL USB RF Power Sensor KC9531 4GHz


SKU: 9531 Category:


KC9531 is a power sensor for industrial microwave application scenarios, used to monitor the power parameters of stable microwave sources. It can adapt to the harsh environment of industrial sites and can correctly measure all kinds of stable power sources.

Product application
Solid-state microwave source power monitoring
Power monitoring of magnetron microwave sources with stable DC power supply
Other occasions where continuous wave power monitoring is required

If you need to monitor unstable, non-continuous wave signal (such as ordinary magnetron microwave source), please use KC9532

1: Use appropriate couplers and attenuators. If the field electromagnetic environment is too harsh, you need to add proper magnetic ring to the power cable, CAN or USB cable.
2: Uncertainty increases when the range of 10~45℃ is exceeded.
3: When used in a vibration environment, the sensor should be fixed with mounting bolts on the sensor body and connected with flexible cables. When used in a vibration-free environment, it can be supported by the RF port only.
