Applications
 | Plastic and Containers39DL PLUS™ ultrasonic thickness gauges can nondestructively measure the material wall thickness of plastics and containers for critical applications in many manufacturing industries. For instance, if a material is too thin, it may fail in use. If it is too thick, the manufacturer could waste money on excess resin. Individual and/or multilayer measurements are possible for up to four layers, take only a few seconds each, and can be recorded on gauge data loggers for documentation and analysis.

Nodularity in Cast Iron / Elastic ModulusFor quick and nondestructive evaluation of iron casting (made by mixing carbon, silicon, and other additives into molten iron), the preferred method is ultrasonic testing. The 39DL PLUS thickness gauge can provide a direct readout of sound velocity in cast iron and other materials based on an entered thickness. In addition, computations (Young's modulus and shear modulus of elasticity, and Poisson's ratio) based on measured sound velocities and material density using the 39DL PLUS thickness gauge can determine homogenous, isotropic, and nondispersive materials. This includes common metals, industrial ceramics, and rigid plastics such as polystyrene and acrylic. Related Content:Measuring Nodularity in Cast Iron |  |

Gun DrillingGun drilling is the process of drilling a hole along the center axis of a solid rod or bar that has a known outside diameter. It is important in the gun drilling process to monitor the position of the drilled hole to ensure that drifting has not taken place. The 39DLP gauge can measure and provide the wall thickness information required to help ensure that the gun drilled hole is within concentricity specifications. Related Content: |  |
