We can find two groups. On one hand sensors or meters with optional data acquisition and on the other hand, universal or multiparameter dataloggers.
It is important to highlight the sensors for specific applications like transport or storage, vibration measurement for sensible goods, etc.
One parameter or combined parameters devices can be found in almost every portable equipment. You can get information from these equipment in the section corresponding to the measured variable or in the specific section of portable meter.
Regarding universal dataloggers, we can highlight:
E-Log y M-Log system. Hand devices for the acquisition of universal signals (mVdc, mAdc, Vdc, RTD, TC, pulses) with its corresponding equivalence in engineering units (depending on the sensor and connected magnitude). Some of them have an automatic recognition of sensors in specific applications and universal software or specific for the application.
CMC systems. Universal system installed in a proof case with optional local printer, inputs RS485 for extension of devices, etc.
Compact systems like GL2000, METROLOG, etc.
