Power Draw Meter

Introduction

The power draw meter is a new generation of intelligent multi-channel electricity testing product. It is a multi-functional power meter with wide frequency and high accuracy, which can realize DC and 0.5Hz-100kHz broadband testing. In addition to the basic electrical parameter measurement function, it also has the functions of automatic measuring range, harmonic analysis, transformation ratio, averaging, filtering, large value locking, electrical energy integration, etc. The standard test software can display, store and call the measured data and waveform.

Unit of Measure

Power is defined as the work done in unit time. The basic unit is watt (W), and 1W is equal to the work done by 1J in 1 second. Common power units include megawatt (1MW=10 ^ 6W), kilowatt (1KW=10 ^ 3W), milliwatt (1mW=10-3W) and microwatt (1 μ W=10-6W), pitot tile (1Pw=10-12W).

Another commonly used power unit is expressed in decibels milliwatts (dBm). It takes 1 milliwatt as the reference level P0=1mW, and the actual power value P (mW) is compared with P0 to take the logarithm. This is the absolute unit of power.

Decibel Watt (dBW) can also be used as the power unit. At this time, P0=1W, that is, 1 dBW=30 dBm.

Composition

The power draw meter consists of a power sensor and a power indicator. Power sensor, also known as power meter probe, converts high-frequency electrical signals into electrical signals that can be directly detected through energy. The power indicator includes signal amplification, conversion and display. The display directly displays the power value. The praxis power meter and the power indicator are connected by cables. In order to meet the needs of different frequencies, power levels and transmission line structures, a power meter should be equipped with several power meter probes with different functions.

Classification

1. It can be divided into thermistor type, thermocouple type, detector diode, dry load type, fluid load, mechanical force effect metal sheet type, Hall effect semi conductor type and electron beam type

2. It can be divided into high wattmeter (10W), medium digital watt meter (10W~100mW), small powermeter and ultra small power meter (1 μ W)

3. It can be divided into terminal type and through type according to measuring circuit

4. Divided into continuous wave power meter and pulse peak power meter according to measured power

5. Divided into coaxial power meter and waveguide power meter according to transmission line

Effect

1. It is used to measure the absolute optical power or the relative loss of optical power passing through a section of optical fiber. In the optical fiber system, measuring the optical power is the most basic, much like the multimeter in electronics. In optical fiber measurement, optical power meter is commonly used for heavy load.

2. By measuring the absolute power of the transmitter or optical network, an optical power meter can evaluate the performance of optical devices. The combination of optical power meter and stable light source can measure the connection loss, check the continuity and help evaluate the transmission quality of optical fiber link.

Application

The power draw meter is widely used in the energy consumption test of household appliances, lighting appliances/LED lamps, motors and motors, chargers and switching power supply, etc. It is very suitable for scientific research universities, testing and calibration, enterprise research and development, quality inspection and other high demand occasions.
