  1. Please pay attention that the media should be compatible with the contacted parts; please inform the density of the media (except water);
  2. Two kinds of cable are optional, polyurethane, and polyethylene. The default is polyethylene. Polyurethane cable is more flexible and endurable; it can be selected due to the requirement;
  3. When the product is used in a thunderstorm area, we suggest the user to use a protection device to protect the product and power grounding reliably;
  4. For a special requirement, please feel free to contact us;
  1. When ordering, please pay attention to the 5V DC power supply. If the cable is connected out of line, the cable length should be less than 10m; When the order output is 0V to 10V DC product, the power supply is 15V to 28V DC;
  2. 24V DC power supply (V1), see “Specification” for detail about Power supply
