Selecting a Displacement Sensor / Measuring System
When it comes to188abc金博宝 and measurement systems, selecting the most appropriate type of device according to the application, required accuracy, and usage environment is necessary. There is a variety of points to consider in determining which device is best for you.
- Desired measurement accuracy
- Target material and characteristics
- Target shape and application
- 使用环境
- Number of devices to use and installation costs
- Selection According to Desired Measurement Accuracy
- 根据目标材料和特征进行选择
- Selection According to Target Shape and Application
- Selection According to Number of Devices to Use and Installation Costs
Selection According to Desired Measurement Accuracy
Measurement accuracy varies greatly depending on the measurement system used.
| 所需的准确性 | Example measurement system |
|---|---|
| 1 mm units | 规模, measuring tape, ruler |
| 0.1 mm units (100 µm units) | Vernier caliper |
| 0.01 mm units (10 µm units) | Micrometer, dial indicator, displacement sensor/measurement system |
| 0.001 mm units (1 µm units) | 位移传感器 /维度测量系统，测量显微镜，坐标测量机，电千分尺 |
The ideal measurement system will vary depending on the range of measurements sought. For those measurements, it's also necessary to look at the capabilities supported by each measurement system, such as whether the results can be viewed with the naked eye, or if the measurements need to be viewed using software.
根据目标材料和特征进行选择
Hard/Soft Targets
For targets made from hard material (such as metal), measurement systems that come into direct contact with the target (such as vernier calipers and micrometers) can be used. On the other hand, targets made from soft material (such as synthetic resins) cannot be measured correctly using measurement systems that come into direct contact with the target. Such targets require non-contact measurement systems that use laser beams.
Opaque/Transparent Targets
如果目标是不透明的，则有多种测量系统能够测量必要的位置。但是，对于透明的目标，必须选择测量系统以匹配目标的材料。对于固化的树脂材料（例如塑料），可以使用千分尺或其他接触型测量系统轻松进行测量。对于薄膜等软目标，应使用激光位移传感器或其他非接触式测量系统。
Selection According to Target Shape and Application
When selecting a measurement system according to the application, it's necessary to take into account the shape of the target in order to select the most appropriate device.

Selection According to Number of Devices to Use and Installation Costs
When selecting a device, the number of people that will use and the degree of frequency at which those people will use the device at the measurement worksite should also be taken into account. The price and availability of equipment investment should be considered when selecting a measurement system.
Large-scale Measurement System Introduction
Measurement systems frequently used in manufacturing worksites include rules and vernier calipers. Such devices can be used for measurement at 0.1 mm to 1 mm units and have been adopted by many as personal-use measurement systems.
在特定过程中使用的测量系统
Measurement systems are also used for inspections on manufacturing lines, such as for checking the dimensions of molds. Each target will call for different accuracy requirements, so measurement systems should be selected according to the desired accuracy. Generally, measurement systems with higher accuracy tend to be more expensive. With such devices as 3D measurement machines, improvements or modifications to the installation environment may also be necessary.
