Resistance thermometer MBW T12

platinumprobeanalog

The MBW T12 is a highly precise and stable platinum resistance thermometer (PRT) based multichannel 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. Using one of three user selectable currents, the T12 repeatedly scans all 12 channels. Employing a full reversal current source, the T12 eliminates polarity sensitive errors normally inherent in DC measuring techniques. Accuracy is further enhanced by referencing all measurements to high stability internal reference resistors. The supplied software allows each channel to be individually programmed with ITS-90 or Callendar-Van Dusen coefficients for direct conversion of resistance measurements to temperature. The MBW T12 connects to a PC over the RS-232 Interface. 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. The T12 is often used for climatic chamber mapping. • Twelve channel temperature measurement • High precision, stability and repeatability • Internal reference resistors • PC software for system control and data acquisition • Simple to configure and use
