Reliable CAN Measurement Technology
The CNT evo is a high-precision measurement module designed for measuring frequencies, pulse widths, incremental displacement measurements, rotation angles, position measurement, event counting and period measurements.
The measurement module CNT4 evo is a further development of the CNTMM series. Its functional range is identical to the former measurement module CNTMM 4 pro. In addition, the CNT4 evo is prepared for the use of TEDS-capable sensors. Moreover, CAN ID and measurement data rate can be set separately for each channel.
The CNT4 evo features four electrically isolated measurement inputs and therefore 8 logical channels for measuring:
Each physical channel can read two measurement values simultaneously, which means that CNT evo modules provide eight logical channels. On/off trigger thresholds are adjustable per channel and feature a switchable AC coupling. Also, these modules are equipped with a galvanically isolated sensor excitation.

CSM’s AD MiniModules of the AD CAN MM (MiniModule)-Series offer a wide range of applications for measuring analogue signals (voltage, current, pressure, flow rate, etc.).
CSM’s Thermo MiniModules (THMM) allow precise distributed temperature measurements with K-, J- and T-type thermocouples: ideal for measurements in the powertrain, on HVAC (Heating, Ventilation, and Air-Conditioning) components, in the vehicle interior, the powertrain development and many more.
The optimisation of processes in the compustion or electrical engine, the clutch and further components of the powertrain help to improve the performance and the smooth running of an engine and to reduce its emissions. In this respect, the smooth interaction of sensors, control units and actuators in different operating states is a key element since it ensures a flexible control of the individual components; regardless of whether it involves model-specific starting and gear shift operations or the appropriate use of a fan for effective engine cooling.
Numerous measurement variables in vehicle development and testing can be recorded with sensors that reproduce their respective measured variable as an analog voltage. For example, distances, pressures, flow rates, moisture, vibrations and also noise can be easily measured.
