RS232 Output 1m Ultrasonic Level Meter 40KHZ Frequency IP67 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.

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.
