IAS: Analogue Current Sensor for High-Side Shunt-based Current Monitoring
(firmenpresse) - At the Sensor+Test fair in Nuremberg, Isabellenhütte unveiled its precision current sensor with analogue voltage output. The new sensor, the IAS, does not require a digital interface or digital converter, reducing size and costs – an important benefit for users in many different fields (e.g. automotive applications, energy management systems and general current sensing applications). The choice of used shunts ranges from 0.1 to 1 mOhm, meaning the measurement area and the dynamic range can be set for up to 100 dB; with a 500-µOhm, for example, pulse current of 800 A can be measured for 100 ms at a resolution of more than 20 mA.
The IAS is a good alternative to magnetic converters and boasts advantages such as shunt-based measurement with good long-term stability of more than 0.5 %, good linearity coupled with high dynamic response, and compact dimensions to the point.
The IAS is also a suitable alternative to DIN Shunts. Here, the main benefits lie in the far lower losses coupled with greater resolution caused by the use of low-resistance shunts.
A further merit of the new sensor is high-side measurement, meaning no separate supply voltage is needed. The typical offset for unidirectional operation is < 3 µV. The operating temperature range can be adjusted within a range of – 40 to + 125 °C, depending on the application. The use of a controller enables customers to read out or process the 0 - 5 V output signals.

Unternehmensinformation / Kurzprofil:
Isabellenhütte Heusler GmbH & Co. KG has its roots in more than 500 years of smelting and metal processing. The company was first documented in 1482. In 1827, it was transferred to the Heusler family. Today, it is one of the globally leading producers of low impedance high precision and performance resistors. In 1987, Isabellenhütte Heusler was the first business in the world to produce SMD mOhm current sensing resistors. Other business areas include producing thermoelectric and resistance alloys and measuring technology products. Employees at the office and production site in Dillenburg (Hesse) number approximately 500.
