Reliable CAN Measurement Technology
The CAN-based CNT MiniModules (CNTMM) “classic” and “pro” are high-precision measurement modules designed for measuring frequencies, pulse widths, incremental displacement measurements, rotation angles, position measurement, event counting and period measurements.
Both module versions feature four electrically isolated measurement inputs for measuring:
CNTMM 4 classic
Each physical channel can read two measurement values simultaneously, which means that CNTMM 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.

Allround measurement modules for sensors with analog voltage outputs: CSM’s AD MiniModules (ADMM) 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 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.
Regardless of whether it involves measurements of oil circuit pressure, the flow rate in the cooling circuit or a vehicle's ground clearance, many sensors convert their respective measured quantity into an analog voltage which can be processed in one of CSM's analog measurement modules.
