TTI-22 - An Overview
The TTI-22 measures temperatures in °C, K or °F with exceptional accuracy. Combined with calibrated
high-precision platinum resistance thermometers, TTI-22 allows a reduction of system measurement
uncertainties to an absolute minimum of as little as 1mK (0.001°C).
Connect TTI-22 to one or two Pt 100 industrial platinum resistance thermometers, whose temperature is
calculated according to DIN IEC751. Pt 25.5 or Pt 100 standard platinum resistance thermometers are also
suitable for use as temperature sensors. The temperature of standard thermometers is calculated according
to ITS-90 (International Temperature Scale 1990). Individual calibration parameters for up to 30 different
sensors can be stored. This provides easy recalibration and good traceability of the temperature
measurement.
TTI-22 is operated via a menu-driven user interface. The current value, the mean value and the standard
deviation of 5 up to 50 values can be continuously displayed. The self-heating effect of the sensor can be
determined via the integrated self-heating test. TTI-22 has a serial RS232 interface and an Ethernet terminal.
The installed web server delivers all important data to any given browser via internet or intranet.
