"The fuel level sensors "STRELA" with analog output are used to connect any trackers that have a voltage input <10V (STRELA with 0-5V output) or 10V> (STRELA with 0-10V output). The sensors can be used in car tanks, tractors, and other machines with a nominal onboard voltage of 12 or 24V. In this type of vehicle, only sensors with a 0-5V output can be used (the special version of 0-7V is also possible). It is not recommended to install "STRELA" sensors with a 0-10V output voltage in vehicles with a 12V onboard voltage."
