规格参数

DESCRIPTION:
Dual-Scan belongs to the xx-Scan device family, as well as AD-Scan, Thermo-Scan and Baro-Scan. It collects measurement data and transmit it to a host (PC/laptop, data logger).

The communication between Dual-Scan and the host is either done via a High-Speed CAN bus or alternatively using the SMB bus (Serial Measuring Bus defined by Bosch).

Dual-Scan provides 7 inputs for connection of NiCr-Ni thermocouples (type K). Due to digital alignment and linearization with online cold junction compensation, Dual-Scan achieves a typical measuring accuracy of ±1 °C throughout the entire measuring range from -100 °C to +1372 °C.

A broken sensor connection is automatically recognized. Approx. every 150 ms the temperature values are updated in the internal buffer or sent via CAN bus.

Dual-Scan provides another 7 inputs for analog differential voltages from -3,5 V to +16 V with a resolution of 5 mV. They are cyclically measured, stored and updated in the internal buffer approx. every 15 ms in SMB mode, or sent via CAN bus.

The currently measured values and the state of operation are permanently shown on the back-lit LCD. The power supply of 8 V to 32 V can be passed through from device to device, according to all xx-Scan devices.

Because of their easy handling and the good cost performance ratio Dual-Scan is well suitable for a wide range of applications, particularly for automotive measurement systems.

COMMUNICATION VIA SMB BUS
Communication via SMB bus is fully compatible and without any limitation to all "SMB bus only" devices of the xx-Scan family.

Using selectable device addresses it is possible to cascade up to 8 devices of different types and in arbitrary order on a standard RS232C interface. Dual-Scan can be of course also used with an USB interface via USB / RS232 adaptor.

Control of the measurement process and data recording is supported by standard software of leading suppliers like INCA from ETAS, VISION from ATI (Accurate Technologies Incorporation), the new calibration system CalDesk from dSPACE, CANape from Vector and other.

COMMUNICATION VIA CAN BUS
New: Using version 3.00 or later, the measurement data can be transmitted with full resolution and speed via High-Speed CAN bus.

Configuration for the CAN bus is done like other xx-Scan devices with the CSM Config Tool. It is a very easy to use Windows based application, which allows to configure CAN bus parameters, device type as well as type and number of measurement channels. Device specific settings are stored permanently in the device itself. All settings are passed to an configuration file, which is compatible with the industry standard CANdb from Vector.

The advantages of data acquisition via CAN bus can be used with all above mentioned software products, e.g. with INCA from ETAS. Quasi-simultaneously other signals can be measured via SMB bus.
