Fluid level measuring module e.g. swimmer, for use in fluid supply system, has room temperature sensor element producing reference signal, which is compared with another signal and deliver corresponding control signal through output

摘要

The module has a room temperature sensor element (RO) producing a reference signal (VO). A sensor element (R1) is arranged in a preset position of a container (3), and produces a signal (V1) corresponding to temperature changes. A measuring unit contains a controller (111), which has inputs (AD0-AD3) and an output. The inputs are connected with the element (RO) and the sensor element. The signal (VO) and the signal (V1) are transmitted to the controller. The signal (VO) and the signal are compared with one another and deliver a corresponding control signal through the output. An independent claim is also included for a fluid supply system.
