We have a couple of preview pictures of the sensor voltage scaler that we will be releasing when we begin selling the Teabox. It works by taking an input signal from a sensor, applying a gain factor to the signal (effectively multiplying it) that is controlled by a pot, and then applying an offset to the signal. It will allow you take a voltage and put it in the range you desire to optimize a sensor for performance in any given context.

There are two styles that we’ve created. One uses right-angle pots that you can use your fingers to adjust (or attach knobs). The other uses a phillips-head screwdriver-type pot for the settings. The later is more precise for making adjustments and also won’t get accidentally bumped so easily.

Below is a picture of a scaler connected to a pressure sensor.
