IAS sensor provides precise current measurements

The IAS sensor does not require a digital interface or digital converter.

The choice of used shunts ranges from 0.1 to 1mohm, meaning the measurement area and the dynamic range can be set for up to 100dB; with a 500uohm, for example, pulse current of 800A can be measured for 100ms at a resolution of more than 20mA.

The IAS is an alternative to magnetic converters and has advantages such as shunt-based measurement with long-term stability of more than 0.5 per cent.

It offers good linearity coupled with high dynamic response and compact dimensions to the point, according to Isabellenhuette.

The IAS is also a suitable alternative to DIN shunts.

Here, the main benefits lie in the lower losses coupled with greater resolution caused by the use of low-resistance shunts.

The sensor also offers high-side measurement, meaning no separate supply voltage is needed.

The typical offset for unidirectional operation is less than 3uV.

The operating temperature range can be adjusted within a range of -40 to +125C, depending on the application.

The use of a controller enables customers to read out or process the 0-5V output signals.
