1. Introduction of ZDY-N DC High Current Sensor

ZDY-N DC high-current sensor is a new type of Hall-detecting current sensor. It has reliable operation, stable performance, accurate measurement, good linearity, fast response, low power consumption,

significant energy saving, and excellent performance-cost ratio. , is an ideal DC current measurement and control equipment.

The well-designed ZDY-N DC high-current sensor has a unique level of technology and craftsmanship.

• Adopt fully-encapsulated epoxy resin encapsulation to protect electronic devices that have undergone stringent screening and technical processing from environmental corrosion and ensure long-term reliable operation of the sensor;

• Adopting scientific automatic temperature compensation technology to make the sensor stable under different ambient temperatures with minimal temperature drift.

• Solve the problem of stray magnetic field interference from the principle and structure design to ensure the accuracy of on-site measurement.

ZDY-N DC high-current sensor has a small structure, no attachment box, opening method, installation, use, maintenance, calibration is very convenient.

ZDY-N DC high-current current sensor has two functions for measurement and control. It is applicable to the measurement and 

control of DC measurement and control systems in the fields of metallurgy, chemical industry, electroplating, pesticides, and electricity .

ZDY-N DC high-current current sensor and PF series secondary metering instrument are used together to form a full-featured DC high-power system integrated test and metering device, which can simultaneously complete the 

system current, voltage and power, and the current hours, voltage hours and Measurement of electrical energy.
