3000mm Detection Range RS485 Output IP67 Protection Ultrasonic Level Sensor for Distance Measurement

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 is 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 setting the request distance after power restart.

There is 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.

For more information please contact us for the software engineering guide.

If the sensor is installed at the environment temperature fall below 0℃,It should do well on the protective measures. In case of direct mounting of the sensor in a through hole using the steel nuts, it has to be fixed at the middle of the housing thread.
