RS485 Output 1m Liquid Tank Level Meter 40KHZ Frequency IP67 Water Level Sensor

RS232 Output Signal low cost price ultrasonic liquid level meter gauge ultrasonic tank water level sensor.

The ultrasonic sensor features a switch output with two teachable switching points. These are set by applying the supply voltage - UB or + UB to the TEACH-IN input. The supply voltage must be applied to the TEACH-IN input for at least 1 s. LEDs indicate whether the sensor has recognised the target during the TEACH-IN procedure. Switching point A1 is taught with - UB, A2 with +UB. Eight different output functions can be set.

Switching point, Setting distance only after power on. The internal clock can assure can't be changed after 5 mins when power on. If want to change the switching point, the user can only setting the request distance after power restart.

• TEACH-IN window mode, normally-open function

A1=blind range, A2=nominal distance

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.
