Differences Between Single-Point and Multi-Point Laser Displacement Sensors

Laser displacement sensors are commonly used high-precision devices for measuring displacement, distance, and shape. Two common types are single-point and multi-point sensors.

1. Single-point laser displacement sensors measure displacement or distance at a single point, typically using a single laser beam and receiving reflected light to calculate position. They offer high accuracy and fast response, suitable for precise single-point measurements.

2. Multi-point laser displacement sensors can measure multiple points simultaneously using multiple beams or scanning lasers and multiple receivers, providing wider coverage and higher measurement efficiency.

Key differences:

Measurement method: single-point measures one point; multi-point measures several points simultaneously.

Coverage: single-point has a narrow coverage; multi-point covers a wider area.

Efficiency: multi-point acquires multiple data points at once, improving efficiency.

Cost: multi-point sensors are generally more expensive than single-point sensors.

Select sensors based on application needs: single-point for high-precision single measurements, multi-point for monitoring multiple points simultaneously.
