How sensitive are your ultrasonic sensors?

Our sensors can detect very small objects and changes, with sensitivity varying by model and frequency. For example, our bubble detection sensors can identify bubbles as small as 1mm in diameter.

What is the typical detection range?

Detection range varies by sensor type and application, typically from a few centimeters to several meters. Each sensor model specifies its optimal detection range and beam characteristics.

How do environmental conditions affect sensor performance?

Temperature, humidity, air currents, and acoustic noise can affect performance. Our sensors are designed with compensation features and environmental ratings for reliable operation in various conditions.

Can sensors be customized for specific applications?

Yes, we offer customization services including frequency tuning, housing modifications, cable length changes, and specialized mounting options to meet specific application requirements.

What output signals do your sensors provide?

Our sensors typically provide various output options including analog voltage, digital signals, pulse outputs, and communication protocols. Specific options depend on the sensor model and application requirements.
