Featuring 2 channels of water level switching and 3 of thermistor temperature measurement, this low cost add-on is ideal for applications involving level control and temperature measurement. It was originally designed for a milk storage and chilling system with vat cleaning, but is equally suited to applications in washing equipment, brewing or liquid food processing.
The principle of the water level detection is that you have electrodes in the water. One electrode is a “common”. Typically this will be at the bottom of the tank, or if the tank is metallic it might be the tank itself. You then have one electrode per level that you need to sense. Once the water bridges the gap between the common electrode and a “level” electrode, the board senses the electrical conduction and provides an “ON” input to the controller.
NOTE: The animation shows 3 levels. The SPice10200 has 2, while the SPice10205 has 6.
Thermistors provide very economical temperature measurement in the range -50°C to an upper limit of 350°C. We provide an extensive tutorial and tools to make it easy for you.
Compatibility: MMi202, SL100, MS120
