One of the key challenges in modern systems design is being able to test and demonstrate there are no low power, or quiescent power, issues with your system design. This is especially true for systems that consume relatively high power when operating, but very low power when in a dormant or standby state. The problem is that it is often difficult to find instruments that can measure both the highest and lowest current levels with the same resolution and accuracy.
Our line of Sens-X current measurement products do just this. By optically coupling a very high-resolution, miniature, front end circuit to a high-speed digital messaging system, add2’s Sens-X instruments can measure ultra-sensitive current signals while still maintaining exceptional signal quality. There are two different lines of Sens-X instruments: the Sens-X CMS in-fuse vehicle current sensors and the Sens-X TVC total vehicle current measurement unit.
Sens-X CMS in-fuse vehicle current sensors
The Sens-X CMS line of point of measurement devices can be plugged directly into a fuse holder, fuse boxes, and similar receptacles. They are specifically designed for test, development, and systems engineers looking for compact, high dynamic range current measurement that can be used in vehicles and vehicle breadboards. Key features include:
- Ease of use. A range of ‘Plug and go’ devices for many points of measurement. Ranges from 5A to 50 Amps are available in 5A steps.
- Quick set up. Using a pre-configured VISUALCONNX GUI each fuse can be monitored and configured to ‘stream’ its data onto CAN.
- HIL integration. Using CANdB files and VISUALCONNX, a network can be built up to support your HIL test requirements.
- Avoids cutting wires or other invasive measures which may reduce reliability
Their small size over come many of the mechanical constraints associated with in-vehicle current measurement, making them perfect for applications, such as vehicle integration, robustness testing, test boards, prototype vehicles, automotive power testing and optimisation, quiescent current monitoring and data logging.
The Sens-X TVC current measurement unit is designed for test, development and systems engineers looking for a high dynamic range current measurement instrument that can be set up quickly and easily. The Sens-X TVC units can measure total vehicle currents as low as a few mA up to nearly 1000 A without physical range changing.
Due to its wide, single supply voltage and non-switching path circuit, in conjunction with low-noise measurement, the unit is suitable for:
- Complete vehicle current monitoring
- Heavy load monitoring
- Cranking issue capture
- Quiescent current investigations
- Distributed measurement
Using CAN to configure and broadcast the current and voltage signals, the unit may be set-up using a pre-supplied VISUALCONNX GUI user interface, allowing you to either integrate with existing CAN-based measurement systems, or create your own using VISUALCONNX GUI run-time and COMMDongle.
