NEW PRODUCT – Panel Temperature Meter / -30 to +70 ° C

Window-30

NEW PRODUCT – Panel Temperature Meter / -30 to +70 ° C. Put a temperature meter anywhere with this very handy display. This panel meter displays the temperature of the attached waterproof 1% thermistor in °C. It does require a DC voltage to run, at 4.5-30VDC. It has reverse polarity protection in case you swap the power leads by accident.

Window-1-18

To use, simply connect the thin red wire to a positive supply, and the thin black wire to ground. Then tape the black thermistor bulb to whatever you want to measure – or leave it loose to measure ambient temperature. The display has a microcontroller that will read thermistor resistance and display the corresponding temperature from -30°C to 70°C with 1 °C precision on a 3-digit 0.56″ tall 7-segment display. The meter draws 3-4mA to power the microcontroller and display. This particular LED display is a nice vivid blue, which we found very readable. To mount to your enclosure, simply cut a 45.5mm × 26.5mm rectangle and snap it in.

  1. Celsius is not a problem for me, but most Americans it is. Is there a hack available for F?

  2. What is needed to make this read up to 220C? I need a couple of temp displays that can read that high.

  3. Is it possible to extend the leads on the thermocouple (to, say, 2 meters) without too much loss of accuracy?

Sorry, the comment form is closed at this time.
