# Which materials are suitable for ultrasonic sensors?

## Suitable media for ultrasonic sensors

Ultrasonic sensors are applicable even for difficult environments. Distance to the object is determined via a sound transit time, ultrasonic sensors have excellent background suppression. The sensors are able to measure in dusty air or through paint spray mist. 

 

**Liquids:**

- Clear water, cloudy liquids, oils or black coffee. ultrasonic sensors can be used with nearly any liquid. The liquid surface should have no foam.
- Thin deposits on the sensor membrane do not affect sensor function.

 

**Colors:**

- Do not affect Balluff ultrasonic sensors. BUS sensors reliably detect all colors.

 

**Transparent layers:**

- Glass plates, plexiglas and razor thin foils …BUS ultrasonic sensors reliably detect transparent layers.

**Surfaces of bulk materials:**

- BUS reliably detect the fill-level of fine sand, shavings or coarse-grained materials.

 

**Surfaces of bulk materials:**

- BUS reliably detect the fill-level of fine sand, shavings or coarse-grained materials.

 

**Material surfaces:**

- Whether velvet, wool or leather …nearly all clothing materials can be reliably detected using BUS ultrasonic sensors.
