CNT evo CAN MM Series

Simple acquisition of digital measurement variables

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.

CNT4 evo

CSM’s CNT4 evo measurement module supersedes the previous versions of CNT4 releases. Its functional range is unchanged and now supports TEDS-capable sensors. Another added capability is the separate setting of CAN ID and measurement data rate for each channel.

The CNT4 evo features four electrically isolated measurement inputs and therefore 8 logical channels for measuring:

  • Frequencies: 0.1 Hz to 300 kHz
  • Cycle / pulse duration: 1 µs to 100 s
  • Duty cycle / PWM: 0 % to 100 %
  • Event counting: 0 to 16 bit (65,535) or up to 32 bit
  • Speed: 0.01 rpm to 600,000 rpm
  • Time offsets: 1 µs to 100 s
  • Up and down counting via pulse/direction or quadrature signal.

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.

Measurement of Digital Signals

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. 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.

Measurement of Analog Voltage from Sensors

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, distance, pressure, flow rates, moisture, vibration and noise can be easily measured.
