ISAscale® 产品主要采用数字式输出信号。这包括 CAN, SPI, LVDS, TTL, RS422, RS485, RS232 或以太网。详细内容参见产品数据页.
标准模拟信号的范围为 4-20 mA 和 0-5 (10) V。也有比率测量模拟信号，其参考值由客户确定。Isabellenhütte Heusler 两合公司的目标是提供纯数字解决方案。Isabellenhütte Heusler 两合公司以此来跟随市场趋势。
为什么 IVT 电压测量装置有 2 个插脚？
IVT 系列有一个 2 插脚的插头用于进行电压测量。但是要注意的是，这两个插脚是彼此相连的（短接），用于高电压电势分接头。关联的接地线是分流器地线。IVT-MOD / IVT-S 数据页
原则上 IVT-MOD-S 怎么安装都可以，因为电流方向的正负号是可以调整的。但是要注意，因为分流器上有一定的电压降，因此进行电压测量时可能会有几 mV 的偏差。因此从精确测量的角度来说，建议按数据页中建议的方式来安装传感器。
以欧姆定律为基础的分流器电流测量方法，其基本原理为著名的公式 U=R*I 。如果电流流过一个电阻（分流器），电阻元件上的电压会下降。该电阻与流经电阻的电流的变化有线性关联。使用特殊的测量方法，我们可以非常准确地确定这一电压，将其数字化并进行分析评估。
How is such high accuracy achieved by shunt-based measurement?
The accuracy is based on multiple factors: In the beginning, Isabellenhütte in cooperation with a supplier of semiconductors, developed low-noise and low-offset semiconductor components which are used throughout our products. Nowadays the shunts produced by Isabellenhütte use resistive materials for their sensitive element, which are melted and processed in-house. This provides a full control of physical and mechanical properties of the materials which results in compliance of the products with the requirements due to specific field of use.
With the help of the company-owned certified calibration laboratory (DAkkS), Isabellenhütte achieves highly accurate current and voltage measurement throughout the production process and with it the transfer of this accuracy to the products. Therefore, all products are also in line with national standards.
What current ranges are covered by ISAscale® products?
Depending on the product family, ISAscale® products cover current ranges from 0 A to 30 kA in both positive and negative direction of current.
How are shunt connectors designed?
The shunts standard shape is flat and comes with a M8 drilling. On request, Isabellenhütte can provide specific shunt shapes, like U or L shapes. Shunts can even be manufactured in a three-dimensional way. Depending on your application and space we can provide you a tailor-made shunt. The shunt can be part of the current bus bar, which allows a space-saving construction.
