Product description:
An overview,
YWG series, hall effect transmitter for hall effect exists generally in the transmitter temperature drift big shortcoming, compensation circuit is adopted to control, effectively reduce the temperature drift of measurement accuracy, ensure accurate measurement;Can measure arbitrary waveform of current and voltage, and according to user requirements to provide standard transmitter output parameters (such as: DC 0 ~ 5 v, 1 ~ 5 v, 0 to 20 ma, 4 ~ 20 ma, etc.), has the characteristics of high precision, easy installation, low cost.
YWG series hall effect transducer is widely applied in variable frequency speed regulating device, inverter device, UPS power supply, communication power supply, electric welding machine, electric locomotive, substation, numerical control machine tool, electrolytic plating, microcomputer monitoring of power grid and the need to isolate detection such as current voltage of the facility.
Second, the principle of
YWG - HTD - 5 - / / / / A current transducer is A kind of original and deputy while highly electrical isolation, dc, ac, pulse current can be measured signals such as linear proportion of convert direct current or dc voltage output of the instrument.It has good temperature characteristic, high linearity, stable performance, product can open up and down, convenient installation, etc.

1) work must be properly connected power supply, output, cannot be wrong answer;
2) for two potentiometer, please do not adjust, if needs calibration, with a small screwdriver slowly rotate to the required precision;
3) the original edge bus temperature should not exceed 60 ℃;
4) when the current bus bar to fill the original edge threading hole, get the best measurement accuracy;
5) using the environment should be no conductive dust and no corrosive action on metals, and damage the insulation gas exists, the height is less than 2500 meters above sea level;
6) test the dc current, current direction and products marked by the arrow direction on the shell, can obtain the positive output.
