BD Series Laser Displacement Sensors (Sensor Head and Amplifier Unit)

The BD series laser displacement sensors can measure thickness, width, level difference, disparity, curve, evenness of target objects by detecting the amount of displacement. The sensors offer accurate and stable measurement with minimal influence from target color or material. The sensor head and amplifier unit are detachable for easier maintenance and up to 8 sensor amplifier units can be interconnected with mutual interference prevention function.

Easy Configuration with Movement Average, Differential, and Median Filters

Movement average, differential, and median filters allow for accurate and stable correction in measurement values in the event of sudden changes from mechanical noise or other variables.

Median filter

Zoom in

removes any sudden value changes.
Movement average filter

Zoom in

averages the measured values to reduce the overall changes to the measurement values.
Differential filter

Zoom in

transmits the differential value between current and previous measured values. Used to measure sudden changes in value.

Various Calculation Functions

Supports various calculation functions (OFF, ADD-AB, SUB-AB, AVG)
- OFF: independent measurement (calculation function not used)
- ADD-AB: Adds the measured values from sensor heads A/B (used to measure thickness)
- SUB-AB: Subtracts the measured values from sensor heads A/B (used to measure level difference/ disparity)
- AVG: averages the measured values from all connected sensor heads (used to measure evenness)
- Cannot use more than 2 calculation functions with interconnected sensor amplifier units

Capable of Measuring up to 1 m

The BD-600 model is capable of measuring up to 1 m suitable for in harsh environment including high temperatures, and also features easy measurement of width and step of thick steel plates.

Maximum Resolution of 1 ㎛

Laser displacement sensors feature a maximum resolution of 1 ㎛ (BD-030) for stable and precise measurements.
The BD-300 model features resolution of 20 ㎛

Dedicated Software ‘atDisplacement’

Dedicated software ‘atDisplacement’ offers user-friendly interface with live data, life graphs and wave graphs for easy monitoring of various measurement values in real-time. Set values can be immediately checked during the setting.

Channel Graph

Zoom in

Real-time monitoring of set value (SV).
Live Data

Zoom in

Displays the status of amplifier unit and measured value to number. The data is automatically scaled for ease of use in future analysis.

Live Graph

Zoom in

Displays the graph color of amplifier unit per channel and present value (PV).
Wave Graph

Zoom in

Displays received light waveform per unit in real time. Up to 8 sensor units can be monitored.

Robot Type Extension Cables for Moving Applications (Sold Separately)
