The first two thermistor and thermocouple sensors convert the heat of the incident signal to a voltage proportional to power.
Microwave power meter.
Usually a microwave power meter will consist of a measuring head which contains the actual power sensing element connected via a cable to the meter proper which displays the power reading.
It measures rf power with the help of temperature compensated thermistor mount from 1 0 uw to 1 omw full scale with 1 accuracy from 10 mhz to 40 ghz depend upon type of thermistor mount.
Get latest price model at 211 b is an automatic self balancing power meter 0 18 ghz.
The head may be referred to as a power sensor or mount.
Power heads are the sensors that convert rf and microwave signals to analog voltages which are read and reported by the power meter.
Typical absorption rf microwave power meter that uses an external sensor when selecting an rf power meter or a microwave power meter it is important to select the correct type of power sensor.
