测试与测量领域：
Knick 解决方案胜券在握

在测试和测量任务中，待测设备通常面临着比常规使用更严苛的要求和环境条件。因此，用于数据采集的测试硬件也必须比日常运行设备具备更高的负载能力。对于这一要求，Knick 隔离放大器、高压变送器和传感器变送器胜券在握。其细节精度体现在全面而深入的技术规范和认证中，具体信息参见设备数据表。

安全、灵活与质量是
应对不断变化测试需求的关键。

在几乎所有行业，严谨的测试对产品最终成功都至关重要。这一点在 Knick 经常涉足且要求严苛的高压市场尤为突出。从电动车到航空航天，从储能到轨道交通：对于高压环境下的测试，检测设备必须具备足够的电气隔离能力、应对不断变化测试条件的灵活性，结合速度与精度，确保获得的数据具有高度可靠性。

在功率硬件在环 (P-HIL) 测试中，高压组件通常位于电路输入或输出端。这就要求硬件环路中的隔离放大器必须在输入和输出通道均实现高度隔离，以保护上下游组件。Knick 隔离放大器专为满足这些严苛要求而设计，在输入、输出和供电通道均采用了三端口隔离技术。

Knick 的隔离技术创造了灵活性，使设备能够在电压不断升高的环境中使用。此外，这种灵活性还体现在输入和输出端的配置功能上，该功能适用于标准产品和专用产品组合中的大多数产品。

为何选择 Knick？
Knick 设备的规格完全满足测试和测量应用的要求。Knick 高压隔离放大器的增益误差 < 0.1 %，且在测量过程中受温度影响极小——而温度影响正是实际应用中常见的误差来源。响应时间以 T90 表示。T90 表示设备在输出端反映输入信号 90% 变化所需的时间。Knick 高压隔离放大器对此类变化的测量可达微秒级。最关键的优势在于高压环境下的安全性，其持续隔离电压超过 1,000 V。

应用亮点：用于数据采集系统 (DAQ) 的高压测量输入

数据采集系统 (DAQ) 常用于面临严苛测试要求的企业，以收集与分析海量数据。这类应用通常需要配备大量输入通道的数据采集硬件，以适配各类待分析的过程变量和电气参数。而在高压环境下，测量设备输入通道的隔离性能若不足，则难以有效保护硬件及其连接设备免受高压冲击，这构成了特殊的工程挑战。

针对这类情况，众多行业领先的数据采集企业均选择 Knick 作为高压数据采集方案合作伙伴：从实质上来看，Knick 为数据采集系统提供高压隔离接口。如果采用 Knick 变送器对高压、电流及温度信号进行隔离，并将其转换为数据采集系统可记录的较低电压输入信号，这些数据采集系统便能安全采集数据，并将其与其他测量变量整合以执行既定任务。

Knick 变送器具备高达 4.8 kV 的持续隔离能力，因此在需要数据采集接口解决方案的高压应用中，成为高压数据采集系统的理想增强组件。
