Measurement Display for Industrial Dielectric Strength Testers

Product Specifications

Technical details and manufacturing context for Measurement Display

Definition

The Measurement Display is a critical component of an Industrial Dielectric Strength Tester that provides real-time visualization of electrical insulation test parameters. It shows key measurements including breakdown voltage, leakage current, test duration, and pass/fail status during dielectric strength testing of electrical equipment and components. The display is designed for industrial environments, featuring a backlit LCD with a resolution of 128x64 pixels for clear readability in low light. It covers a measurement range of 0–10 kV, with an accuracy of ±0.5% full scale, ensuring reliable results. The response time is ≤100 ms for real-time monitoring. The operating temperature range is -10 to 50 °C, and storage temperature is -20 to 70 °C, with a non-condensing humidity range of 20–80% RH. The unit is dust and splash resistant with an IP54 rating per IEC 60529. It operates on a 24 V DC supply (±10%) and consumes ≤5 W. The display size is 4.3 inches diagonal, and the weight is 0.5 kg. The display is housed in a plastic enclosure with a glass or acrylic protective cover, and it includes a PCB with microcontrollers for data processing. This component is intended for integration into dielectric strength testers; it is not a standalone measuring instrument. The listed parameters are directory reference ranges and must be confirmed for the specific model and application. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement or use.

Working Principle

The Measurement Display receives electrical signals from the tester's measurement circuits. These signals are processed by internal electronics, including microcontrollers on a PCB, which convert the analog or digital data into readable numerical values and graphical representations. The processed information is then displayed on a digital screen, typically using LCD or LED technology with appropriate drivers and controllers. The display updates in real time, allowing operators to monitor breakdown voltage, leakage current, and test duration. The working principle ensures accurate representation of the measured parameters, with a response time of ≤100 ms to reflect changes promptly.

Frequently Asked Questions

What is the measurement range of the display?

The display covers a measurement range of 0–10 kV, which is typical for dielectric strength testing. However, this is a reference range; confirm the exact range for your specific tester model with the manufacturer.

What is the accuracy of the display?

The accuracy is ±0.5% of full scale. This ensures reliable readings, but you should verify the accuracy for your application and model, as it may vary.

What is the ingress protection rating?

The display has an IP54 rating per IEC 60529, meaning it is dust and splash resistant. This is suitable for industrial environments, but ensure it meets your specific installation requirements.

What power supply does the display require?

The display operates on a 24 V DC supply with a tolerance of ±10%. It consumes ≤5 W. Always check the power requirements with the manufacturer for your specific unit.
