The units are also available with expanded indicating features and an optional oversized panel box allows for the installation of an engine oil temperature gauge, tachometer and
wattmeter.
A family of RF solid-state Class A power amplifiers is suitable for EMC testing, laboratory testing, antenna and component testing,
wattmeter calibration, medical/physics research, and more.
The power input (heat) is applied to the evaporator region of the heat pipe by using electric heater and measured using electric transducer (
wattmeter).
Next, we use the ZBEMCS and a standard
wattmeter to measure the energy consumption of two electric heaters.
In order to measure the static characteristics, the Yokogawa WT500
wattmeter, whose specifications are reported in [40], has been adopted.
The test procedures specify use of a
wattmeter or a watt-hour meter for standby power measurements.
The compressor power consumption is obtained using a digital
wattmeter, and its speed is measured with a calibrated signal from the inverter drive.
Consumed power during the cutting process was measured on deep holes boring machine MGA 250 x 1000 using a
wattmeter. The measured data were used to calculate the main cutting force and the total cutting torque.
The power meter is a terminating digital
wattmeter with an input impedance of 50 [omega] Power and frequency ranges of 2 to 500 mW and 10 to 2000 MHz make the model 7100 a perfect choice of numerous low power RF test and troubleshooting applications in product development, repair, field service and manufacturing.
At this point in time, the electric power consumed for the run of the entire RF/V system was also recorded by an integration
wattmeter. After RF/V drying, heart checks and V-cracks were visually evaluated on the end surfaces of disks.
Figure 7 schematically depicts this type of system, together with some of the other ideal sand system features mentioned previously, such as an automatic compactability control at the mixer, weigh hoppers, control of the mixing cycle and bond development using a
wattmeter (a scanner to detect unpoured molds at shakeout so that the bond and carbons additions can be adjusted), a lumpbreaker after the shakeout, followed by magnetic separators, a homogenizing drum and sand cooler.
