1. Product Introduction
1.1 What Is the KUS3000 Series Ultrasonic Sensor?
The KUS3000 series ultrasonic sensor is a sensor developed by KACISE for industrial automation applications. It features faster response speed and more flexible installation options.
The sensor housing is fully threaded, with a nickel-plated brass housing as standard, offering strong anti-interference performance. Other housing materials can be customized, such as PTFE corrosion-resistant housings.
The maximum measuring distance covers 1 m to 15 m. The product lineup includes KUS3000-M18, KUS3000-M30-Type1, KUS3000-M18-Type2, and KUS3000-M18-Type3.
The KUS3000 series supports NPN and PNP switching outputs, 4–20 mA and 0–10 V analog outputs, and RS485 Modbus communication. It is suitable for various industrial measurement scenarios. RS485 can be integrated with a 4G module to enable real-time monitoring of measurement values.
1.2 Advantages of the KUS3000 Series Ultrasonic Sensor
- Non-contact measurement, no contact with the measured medium
- High accuracy, up to 0.5%
- Optional voltage output
- Fast response speed

3. Explanation of Core Selection Parameters
| Parameter | Description |
| Measuring Distance | The maximum distance that the sensor can measure |
| Blind Zone | The distance from the sensor face within which measurement is ineffective |
| Protection Rating | Indicates the device’s resistance to dust, water, and foreign object intrusion |
| Output Signal | The output form of the sensor. PNP and NPN are switching outputs commonly used for industrial control; 4–20 mA is an analog output for process monitoring; RS485 can be understood as the digital output of the sensor |
| Temperature Compensation | Changes in ambient temperature affect the speed of sound and can cause measurement errors, therefore temperature compensation is required |
4. Step-by-Step Selection Process
Step 1: Determine the Measuring Range
- Identify the maximum measuring range required in the application environment
- Select a model that fully covers the maximum depth
Step 2: Determine Required Outputs
- Confirm the communication protocol or signal type (e.g., RS485 interface, 4–20 mA analog output)
Step 3: Consider Environmental Conditions
- Identify the operating environment (e.g., corrosive environment, outdoor environment, temperature, pressure)
- Determine accuracy requirements, protection rating, and housing material
Step 4: Evaluate Installation Compatibility
- Download the product manual
- Confirm the installation method based on product dimensions and thread specifications
Step 5: Consult Professionals
- If you are still unsure about the selection, consult the KACISE professional technical team, who will provide more targeted recommendations based on your specific requirements and on-site conditions
5. Typical Application Scenarios
| Application | Recommended Model | Reason |
| Small Liquid Storage Tanks (Tank depth < 1 m) | KUS3000-M18 | Compact size, easy installation. Supports switching output and can work with pumps to control filling and draining processes. |
| Industrial Production Line Counting | KUS3000-M30-Type1 | Maintains a certain distance to monitor products on the production line from above. Product present → distance shortens → switch triggered → counting achieved. |
| Long-Distance Production Line Detection | KUS3000-M30-Type3 | Larger measuring range allows detection of product presence on long production lines. If no product is detected, the switch output can be triggered for alarm purposes. |
