Reliable CAN Measurement Technology
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.
Thanks to the extremely low power consumption, THMM modules have an extremely low temperature drift. These modules provide highly accurate measurement results over the entire operating temperature range from -40 °C to +125 °C. The compact and robust module housings allow direct mounting in the engine compartment or invisible mounting in the vehicle interior.
These modules feature an internal cold junction compensation per channel. The socket contacts are made of the same material as the corresponding thermocouple. This minimizes interferences caused by temperature differences and ensures an extremely good accuracy over the entire operating temperature range.

Modules for temperature measurements with increased accuracy requirements in comparison to measurements with thermocouples: PT MiniModules (PTMM evo) allow high-precision temperature measurements with PT100 and PT1000 RTD elements.
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.).
Temperature measurements play a vital role for the development of components, reducing fuel consumption as well as for the driving comfort, in vehicles.
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.
