I.Product Features

The UM5000 integrated ultrasonic level gauge is an intelligent non-contact level measuring instrument. The product is small size, low power consumption, gain control, temperature compensation, and adopts advanced detection and calculation technology to improve the measurement accuracy of the instrument. It has a suppression function for interference signals to ensure the authenticity of the measurement results. The product can be widely used for measuring the liquid level of various liquids and the height of solid materials, as well as for measuring distance.

II. Application

Liquid level measurement

Container water level monitoring

IV. Wire connection

V: Adjusting the evaluation limits

The ultrasonic sensor features an analogue output with two teachable evaluation limits. These are set by applying the supply

voltage -U_B or +U_B to the TEACH-IN input. The supply voltage must be applied to the TEACH-IN input for at least 1 s.

indicate whether the sensor has recognised the target during the TEACH-IN procedure. The lower evaluation limit A1 is taught

with -U_B, A2 with +U_B.

Two different output functions can be set:

1. Analogue value increases with rising distance to object (rising ramp)

2. Analogue value falls with rising distance to object (falling ramp)

Evaluation limits may only be specified within the first 5 minutes after

Power on. To modify the evaluation limits later,

the user may specify the desired values only after a new Power On.

TEACH-IN rising ramp (A2 > A1)

- Position object at lower evaluation limit

- TEACH-IN lower limit A1 with - U_B

- Position object at upper evaluation limit                                                

- TEACH-IN upper limit A2 with + U_B

TEACH-IN falling ramp (A1 > A2):

- Position object at lower evaluation limit                                              

- TEACH-IN lower limit A2 with + U_B                                   

- Position object at upper evaluation limit

- TEACH-IN upper limit A1 with - U_B                                                                   

Default setting

A1: unusable area

A2: nominal sensing range

Mode of operation: rising ramp
