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.
PTMM evo is a further development of the PTMM series and available in two versions with four or eight measurement channels. PTMM evo thus expands CSM's product portfolio with modules for high-precision temperature measurements for use in distributed measurement applications in test drives and test benches.
A measurement data rate of 100 Hz per channel, an extended operating temperature range of ‑40 °C to +125 °C and last but not least a reduced power consumption make these modules an excellent choice, especially for measurement applications using sensors with short response times.
To achieve best possible accuracy results, PTMM evo modules can be parameterized by means of individual PT coefficients (R0, A, B and C). This allows the use of low-accuracy PT sensors if required.

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.
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.
