3.Application

Current Sensor Test
Metrology Performance	Basic accuracy error
	Zero point output error
	Full range output error
	Linearity error
	Return difference
	repeatability error
Influence Quantity Performance	Power consumption measurement
	Zero drift
	Thermal zero drift (needs to be equipped with a temperature control box)
	Thermal sensitivity drift (needs to be equipped with a temperature control box)
	Overload capacity
	Power supply voltage impact test
	Load change rate (needs to be equipped with a load box)
Other Performance	Measurement bandwidth (requires high-frequency constant current source)
	Response time (requires pulse current source)

 

☆ Metrology Performance Test

1. The direct measurement method (standard source method) is used to test the DC current sensor.
2. The standard measuring tool has two sets of built-in power supply and output measuring instruments, supporting simultaneous detection of two current sensors.
3. The current loop realizes automatic crimping through pneumatic means, improving testing efficiency.
4. Special test software: Users can customize the test plan, including zero point error, full-scale output error, linearity, hysteresis (hysteresis), repeatability error, accuracy, etc., to realize automatic testing of the measurement performance of the current sensor.

☆ Power Supply Impact Test And Power Consumption Measurement

1. Built-in DC ±(5.0 V ~ 50.0 V) adjustable power supply can test the power supply impact of the sensor under test.
2. A standard ammeter is connected in series to the power supply module loop to measure the no-load or full-load power consumption of the sensor under test.

 

☆ Sensor Bandwidth Test (Optional)

1. Optional high-frequency constant current source of 1 mA ~ 10 A, DC ~ 1 MHz and high-frequency voltmeter can be used to measure the frequency response bandwidth of the sensor.
2. Note: The high-frequency voltmeter can choose a six-and-a-half-digit digital multimeter with a measuring frequency of 300 kHz or an eight-and-a-half-digit digital multimeter with a measuring frequency of 1 MHz.
3. If the sensor being tested is a current output type, a high-frequency coaxial shunt needs to be connected for I/V conversion.
4. Note: The sensor bandwidth test defaults to a single sensor unit. If multiple sensors are measured at the same time, it needs to be customized.

☆ Sensor Response Time Test (Optional)

1. Optional equipment such as a pulse current source with a peak value of 500 A and a di/dt of 50 A/μs, a standard pulse shunt, and an oscilloscope can be used to measure the sensor response time by comparing the rise time of the standard signal and the sensor output signal.
2. If the sensor being tested is a current output type, a high-frequency coaxial shunt needs to be connected for I/V conversion.
3. Note: The sensor response time test defaults to a single epitope. If multiple sensors are measured at the same time, it needs to be customized.

 

4. Features

☆ Current Module Combined Output

1. The current source adopts a modular design, and multiple modules can be connected in parallel to achieve large current output, up to 20 kA.

☆Current Supports Program-Controlled Commutation

1. The device has a programmable switching output function in the positive and negative directions of current, which is convenient for detecting the negative polarity characteristics of the current sensor.

 

☆ Direct Display Of Sensor Measurement Errors

1. Advantages of the solution: The mobile measurement and control console interface of the device can display the primary current output value, secondary signal measurement value, and directly display the basic error of the sensor being tested and other measurement results to improve testing efficiency.
