LEGO Sensors From Dexter Industries
Dexter Industries Header & Logo The lack of NXT Sensors in this region has led to the need to directly import and distribute these NXT Sensors from Dexter Industries. Working closely with Dexter Industries, we at Building Blocks will support users from the Asia Pacific region. Building Blocks plans to build a more integrated community for NXT Mindstorms users in this region.

    3rd Party Sensors

    dThermal Sensor
    dThermal 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
    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.  

    Open Thermal Probe
    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.
