Temperature measuring system PT12

resistancemulti-channelhigh-precision

The PT12 is a highly precise and stable platinum resistance thermometer (PRT) based multi-channel temperature measurement system. Using a custom designed high-quality measurement circuit with full current reversal and multiplexed sampling, the PT12 provides 12 channels of low uncertainty temperature data for validation and calibration engineers. Supports THERMOtelligent™ Smart 4-Wire PRTs THERMOtelligent™ Smart-Platinum Resistance Thermometers save you valuable time and decrease the possibility of measurement errors by eliminating the need to change calibration coefficients in the thermometer readout when temperature probes are changed. Adjustable Current Modes Using one of three automatic or user selectable currents, the PT12 repeatedly scans all 12 channels. Employing a full reversal current source, the PT12 eliminates polarity sensitive errors normally inherent to DC measuring techniques. Accuracy is further enhanced by referencing all measurements to high stability, temperature compensated internal refence resistors. Multiple Coefficient Modes The integrated firmware allows each channel to be individually programmed with ITS‐90 or Callendar‐Van Dusen (CVD) coefficients for direct conversion of resistance measurements to temperature. It incorporates a full color, pinch zoom touch screen as the user interface. Although not required for operation, the PT12 may also be connected to a PC over an RS‐232 or USB interface.
