Laser Sensors

When you need to measure absolute thickness, NDC Infrared Engineering laser caliper sensors are designed to make an absolute thickness measurement regardless of varying densities, colors, or other product constituents. There are two sensors in the range:
  • Model 172 Gauge - Laser Caliper - Dual-sided  
  • Model 170 Gauge - Laser Caliper - Single-sided 

 

The Model 172 Dual-sided and Model 170, Single-sided Laser Caliper Sensors are designed to measure absolute thickness of products up to 15mm (0.4 in) thick, independent of product density, making them ideal for profile measurements of products of inconsistent density.

The laser technology incorporated into the design allows the sensors to be insensitive to changes in product color and surface reflectivity.
The dual headed 172 Sensor incorporates lasers on both the top and bottom to determine surface position on both sides of the sheet. The design also incorporates a Radio Frequency Sensor to compensate for any changes in the measurement gap distance. By combining these three pieces of information, the true product thickness is derived.
In the Single-sided 170 Sensor a laser sensor detects the precise location of the top surface of the material, while an RF inductance sensor determines the position of a backing roll, plate, or shoe that the bottom surface of the product is riding on. By combining these two measurements, absolute thickness can be measured.
 
  • Model 172 and 170 features:
  • High Precision Measurement
  • Single-sided or dual-sided measurement
  • Insensitive to Product Density
  • Insensitive to Changes in Color or Texture
  • RF Compensation for Changes in Gap or Roll
  • Compact, Rugged and Easily Maintained 
  • Measurement Range: up to 15mm (0.4in)
