Multi channel reference measurement Thermometer Т12
Multi channel reference measurement system is used to check the climatic chamber, calibrate the system, calibrate the temperature. For applications where fast sampling rates are required, the T12 is the ideal choice. The system can be configured to select all 12 channels in 5 seconds.
The T12 is a precise and stable platinum resistance thermometer (PRT) multi channel temperature measurement system. Using a custom designed high quality measurement circuit, 24 bit analog to digital converters and multiplexor sampling; the T12 provides 12 channels of low uncertainty temperature data for validation and calibration engineers.
T12 repeatedly scans all 12 channels and the low and high range internal reference resistors, with user configurable excitation current. Employing a full reversal current source, the T12 eliminates polarity sensitive errors inherent in DC measuring techniques.
The GeckoR2 software supplied allows each channel to be individually configured with ITS-90 or Callendar-Van Dusen coefficients for direct conversion of resistance to temperature. The T12 connects to a PC through an RS-232 Interface. An RS232 to USB converter is included.
There are four versions available, the T12, T12-S, T12-SE and the T12-E. The new ‘S’ versions feature Smart Connectors that are configured using GeckoR2 with coefficients and calibration corrections, probe position and unique identifiers.
