Capacitive level sensor controller PCS0902



        Description
PCS09xx is a programmable capacitive level sensor controller for liquid handling. The series controllers can detect capacitance which changes below 1pf, and can convert the test results into IO level output and intuitive LED indication. PCS09xx controller provides a simple and convenient set of control commands, which can be connected to the control host through CAN bus (or RS485 or RS232) and directly read the measured values. It is suitable for various medical, environmental protection, reagent level detection for laboratory instruments, container level detection and other application scenarios.
