Metrology Performance Test

TI5000 DC Current Sensor Testing Device tunkia

The direct measurement method (standard source method) is used to test the DC current sensor.

The standard measuring tool has two sets of built-in power supply and output measuring instruments, supporting simultaneous detection of two current sensors.

The current loop realizes automatic crimping through pneumatic means, improving testing efficiency.

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

TI5000 DC Current Sensor Testing Device tunkia

Built-in DC ±(5.0 V ~ 50.0 V) adjustable power supply can test the power supply impact of the sensor under test.

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)

TI5000 DC Current Sensor Testing Device tunkia

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.

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.

If the sensor being tested is a current output type, a high-frequency coaxial shunt needs to be connected for I/V conversion.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)

TI5000 DC Current Sensor Testing Device tunkia

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.

If the sensor being tested is a current output type, a high-frequency coaxial shunt needs to be connected for I/V conversion.

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

TI5000 DC Current Sensor Testing Device tunkia

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

TI5000 DC Current Sensor Testing Device tunkia

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.


High Stability Of Current Source

TI5000 DC Current Sensor Testing Device tunkia

Typical values of short-term stability: 0.003% (class 0.01), 0.005% (class 0.02), 0.01% (class 0.05).

It can effectively ensure good repeatability and consistency in batch testing of industrial products.


Low Ripple Content

TI5000 DC Current Sensor Testing Device tunkia

The ripple content of the current source is less than 0.5%, which can effectively reduce noise interference and ensure the accuracy of test results;

At the same time, it can avoid surge voltage or current caused by strong ripples to ensure safe operation of the equipment.


Direct Display Of Sensor Measurement Errors

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.


Special Test Software (Optional)

TI5000 DC Current Sensor Testing Device tunkia

DC current sensors have many detection items, including zero output error, basic error, linearity error, hysteresis, repeatability error, etc.

Users can choose special testing software and refer to relevant procedures and specifications for sensor testing. Users can customize testing plans (including testing items and testing points, etc.), store, read, edit and manage the tested sensor product library. After automatic testing is completed, users can Test report export.

Software functions can be customized according to customer needs and subsequent software upgrades can be supported.
