Temperature Sensing

    DI-Thermal Series by Dexter Industries is a
    line of temperature sensors for the Lego NXT
    Mindstorms system.  The sensors offer an
    increased range of operating temperatures
    and a high level of accuracy.  

    These thermal sensors can easily be
    incorporated into chemistry, engineering,
    and environmental experiments with NXT-G
    and Labview.

Protected Thermal Probe
(DIThermal-P)

    Constructed of 316 stainless steel, this rugged
    temperature probe is encased in a stainless
    steel shaft that can be used to measure
    temperatures in water, organics, ionic
    solutions, most acids, and bases.   The probe
    has a 1/4" OD, and is 6" long, making it ideal
    for most laboratory experiments and sealed
    distillation experiments.  Solid construction
    offers superior strain relief.  

    Temperature Operating Range: -50C (-58 F)
    to 150 C (302 F)
    Accuracy: +/- 0.5 C
    Response Time: 90% in 50 Seconds
    Precision:
    -50C - 0C +/-1 C
    0C - 50C +/-0.1 C
    50 C - 100C +/- 0.5 C
    100 C - 150 C +/- 2 C


Open Thermal Probe
(DIThermal-O)

    This open thermal probe offers more rapid
    temperature readings.  The probe is for use
    on dry surfaces and can be mounted to
    beakers, distillation columns, and other
    surfaces using steel bands.  The data line
    reaches 2 feet for flexibility of setup, and is
    hooked directly into the NXT.  Solid
    construction and a rugged design with extra
    protection offers strain relief and a long
    lifetime.

    Temperature Operating Range: -50C (-58 F)
    to 150 C (302 F)
    Accuracy: +/- 0.5 C
    Response Time: 90% in 25 Seconds
    Precision:
    -50C - 0C +/-1 C
    0C - 50C +/-0.1 C
    50 C - 100C +/- 0.5 C
    100 C - 150 C +/- 2 C

    NXT-G Quickstart Program - Start datalogging now!  This program was made by Dave Astolfo to
    help users get started with the new thermometer quickly.  The program reads the thermometer data, and
    saves it to a csv file on the NXT.  Check out Dave's review of the thermometer and comparison against
    the official Lego thermometers here.






    LABVIEW - The Labview SubVI provides more precise temperature measurements   
    - 0.1 Degree C precision.
    - Output data is provided in Celsius, Kelvin, Fahrenheit, and Rankine.  
    - For use with the DI Protected and Open Thermal Probe.
