The CSN Series MR current sensor builds on patented Honeywell
technology to offer superior sensor performance and accuracy in current
measuring applications.
The current sensor utilises an ASIC (Application Specific Integrated Circuit)
and a magnetoresistive (MR) Honeywell magnetic sensor to provide
extremely low offset drift with temperature resulting in stable, repeatable,
accurate measurements. This is achieved by using an ASIC to exploit the
unique features of the MR sensor. There is virtually no offset drift over the
entire operating temperature range.
The sensor operates from a +5 V unipolar supply and has an accessible,
internal 2.5 V voltage reference. The sensor can operate from either the
internal voltage reference or an external voltage reference, thus enabling
several sensors to be used without offset imbalance. Three primary pins
enable the sensor to be configured for different measuring ranges and the
current output signal enables different load resistors to be used depending
on the application.
The sensor offers flexibility and performance to meet many applications.
