Other Performance

Response time (optional pulse voltage source required)

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

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

• Special test software: Users can customize the test plan. The test items include: zero point error, full range output error, linearity, hysteresis (hysteresis), repeatability error, accuracy, etc., to realize automatic testing of the measurement performance of the voltage sensor.

• Built-in DC ± (5.0 V ~ 50.0 V) adjustable power supply, which 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.

• Can be used with optional high-frequency voltage source of 10 mV ~ 11 V, 10 Hz ~ 1 MHz and high-frequency voltmeter to measure the bandwidth of the sensor.

• Note:The high-frequency voltmeter can measure a 6.5 digit multimeter with a frequency of 300 kHz or 8.5 digit multimeter with a frequency of 1MHz.

• If the voltage sensor 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 tested at the same time, it needs to be customized.

• A pulse voltage source with a peak value of 200V~2kV and a rise time ≤ 10μs, a broadband voltage divider, an oscilloscope and other equipment are optionally available. By comparing the rise time of the standard signal and the sensor output signal, the sensor response time can be measured.

• If the sensor under test 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.

• Advantages of the solution: The interface of the device can display the primary current output value, secondary signal measurement value, and directly display the basic error of the sensor under test and other measurement results to improve testing efficiency.

• Program advantages: There are many testing items for DC voltage sensors, including zero point output error, basic error, linearity error, hysteresis, repeatability error, etc. If the traditional manual testing method is used, the testing efficiency is low and prone to errors.

• Users can choose our special test software. Referring to the relevant procedures and specifications of sensor testing, users can customize the testing plan (including testing items and testing points, etc.), store, read, edit and manage the tested sensor products. After the library and automatic testing is completed, the test report can be exported.

• Software functions can be customized according to customer needs, and subsequent software upgrades that add new procedure testing requirements are supported.
