Measurement Modules CSMFast, Precise and Flexible Measurements
Flexible, Precise and Reliable Measurement Technology
The measurement modules of our partner CSM are extremely rugged, compact, efficient and highly precise over the entire operating temperature range. CSM has been setting technological standards for years now, especially in the field of decentralized measurement technology. Its CAN measurement modules have proven themselves for over 15 years. They are in continual use worldwide and assure easy measurement of temperature, electrical voltages, mechanical stresses, rotational speeds, etc.
Measurement applications that require higher bandwidths need a fast communication stream with data throughputs which are higher than the CAN bus can provide. Here CSM utilizes Ethernet in conjunction with the EtherCAT and XCP-on-Ethernet protocols. EtherCAT is an established protocol for fast and synchronous measurement from test bench measuring instruments. XCP-on-Ethernet is a standard protocol for on-board ECU technology in the automotive field. The EtherCAT MiniModules from CSM make use of this protocol to enable synchronized high-speed measurements with measurement data rates of up to 1 MHz per channel.
Decentralized measurements in vehicle trials or at the test bench place high demands on measuring instruments. Modules are required to be compact, rugged, reliable and easy to use. Thanks to their minimal package size and IP65/67 level of protection, CSM CAN MiniModules can be mounted directly in a vehicle's engine compartment close to the measuring points with no fear of the harsh environment having an impact on the data measured.

High-Voltage Measurement Systems
Measuring high-voltage components with proven safety in vehicle trials and on the test bench. CSM high-voltage measurement systems were specially developed for safe, precise acquisition of temperatures and analog signals in HV environments, especially in electric and hybrid vehicles. Measurement systems from CSM enable safe HV measurement from the sensor to data acquisition. They can be installed quickly and assure precise and reliable measurement results over the entire operating temperature range.

EtherCAT-based MiniModules from CSM are the optimal solution for measurement applications whose requirements exceed the capabilities of the CAN bus. EtherCAT is an established protocol for fast and synchronous measurement from test bench instruments. It sets standards for bandwidth, maximum number of channels and synchronism of measurement signals. As an Ethernet-based data bus, EtherCAT, offers short cycle times and low jitter. In addition, its distributed clock functionality ensures precise synchronization (≤ 1 μs) of all connected modules, regardless of the size of the measurement setup.

For fast, time-synchronous and mobile measurement of analog voltages at measurement data rates which can be scaled to the measuring task up to 10 kHz, 100 kHz or 1 MHz per channel
For fast, time-synchronous and mobile measurement of analog voltages, especially when IEPE sensors are used (e.g. accelerometers or microphones) at data rates up to 100 kHz per channel
The XCP-Gateway is the interface between the data acquisition software, e.g. vMeasure exp, CANape or other 3rd party tools – and the EtherCAT measurement modules from CSM. It contains an EtherCAT master and an XCP-on-Ethernet slave.

Shunt-based current measurement under harsh environmental conditions. The CSMshunts are looped directly into the current path to be measured and can be connected directly to the CAN-based AD4 or AD8 modules. This results in a cost-effective and compact solution for measurement tasks in 12V, 24V or 48V on-board networks.
Hall-effect-based measurement of highly dynamic currents under demanding environmental conditions: The LEM sensor package is optimized for connection to the fast ECAT AD4 OG modules and is available in different types for 5A to 1250A.
Fluxgate-based solution for fast and easy measurement of currents at high accuracy: the complete solution CSM Current Clamp based on Hioki's proven current clamps allows in combination with the ECAT AD4 OG modules reliable measurements even under difficult environmental and installation conditions in the HV environment. The range includes types with 20A, 200A, 500A and 1000A, optionally with calibration according to DIN EN ISO/IEC 17025 (DAkkS).
