KUS600 Series Ultrasonic Sensor PVDF Non-contact measurement Low power consumption
Features
Non-contact measurement
PVDF casing for corrosion environment
Low power consumption solution
Various output options, wide voltage power supply
KUS600 low-power ultrasonic liquid level gauge is a real low-power ultrasonic sensor with low operating current, the stable time is short and the stability is good. We use nearly new ICs, usually with very low power consumption.The circuit in the sensor consists of three parts, the basic circuit of the transmitting circuit, the receiving circuit and the single-chip microcomputer. The single-chip microcomputer realizes power consumption management by enabling the work of various parts of the control circuit, and then controls power consumption.When the microcontroller itself is not working, it enters sleep mode to further reduce power consumption.

Description of Sensor Functions
Adjusting the analogue output.
The analogue output can be programed as the user want. Such as working at switch output or working at liner output all the parameters can be set by the RS485 interface. There are 8 types of output functions can be programed. All the setting routine as follows, step 1 set one pointed distance by the RS485, step 2 set another pointed distance by the RS485. Step3 set the output type liner or switch, and set the related output options Step4 reboot the sensor. 1. Window mode normally-open and liner mode positive slope output function. 2. Window mode normally-closed and liner mode negative slope output function. 3. Single switching point, normally-open function. 4. Single switching point, normally-closed function. 5. Single switch point with hysteresis gap normally-open function. 6. Single switch point with hysteresis gap normally-closed function. 7. Detection of object presence-normal open function. 8. Detection of object presence-closed open function. Switching point, Setting distance only after power on. The internal clock can assure can't be changed after 5 minutes after power on. If want to change the switching point, the user can only set the request distance after power restart.
For the RS485 output type.
There are 2 kinds of working style, One for auto measure, the sensor will measure the distance or level repeatedly, and the measurement period can be set by the UART. The measure result can be fetched every time. The other style is power save mode when the sensor is sleep, until the sensor received the inquiry command with pre-code. Communication protocol is Modus-RTU. For example the measure result can be read by access the register 0x101 by Modbus protocol.
