|
| ||
| Probe Type: | |||
| Your choices are... | |||
| Touch-Trigger (Discrete Point) Probe | The most common probe type. Discrete point probes actually touch the surface of the work piece. Upon contact, a signal containing the coordinates of that point is sent to the CMM. The probe is then backed off and moved to the next location where the process is repeated. | ||
| Displacement Measuring Probe | Generally referred to as a scanning probe. This method generally involves passing the probe over a target surface at its working range. As the probe scans the surface, it transmits a continuous flow of data to the measurement system. Scanning contact probes may use linear variable differential transformer (LVDT) or optoelectronic position sensing. | ||
| Proximity (Noncontact) Probe | Generally referred to as a scanning probe. This method generally involves passing the probe over a target surface at its working range. As the probe scans the surface, it transmits a continuous flow of data to the measurement system. Noncontact probes, either scanning or discrete can use laser, capacitive or video measurement technology. | ||
| Other | Other unlisted probe type. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

| Mounting | |||
| Your choices are... | |||
| Vertical | The probe is mounted vertically on the CMM. | ||
| Horizontal | The probe is mounted horizontally on the CMM. | ||
| Other | Other unlisted mounting type. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Axes | The directions of gauging relative to the probe's coordinate system. | ||
| Your choices are... | |||
| +X | The probe can sense along the positive x-axis. | ||
| -X | The probe can sense along the negative x-axis. | ||
| +Y | The probe can sense along the positive y-axis. | ||
| -Y | The probe can sense along the negative y-axis. | ||
| +Z | The probe can sense along the positive z-axis. | ||
| -Z | The probe can sense along the negative z-axis. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Measuring Range: | The greatest distance the probe can travel to measure in any direction. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Repeatability: | The quantitative degree of agreement between results of successive measurements of the same quantity under identical conditions. Unidirectional repeatability is specified for touch-trigger probes. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| Stylus Force: | The maximum force applied by the stylus when contacting with the surface being measured. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

| ||
| Sensor Type: | |||
| Your choices are... | |||
| Kinematic (Switching) | Key characteristics of kinematic or switching sensor types include: Wide range of products available, small probe size possible, low over-travel force, simple interfacing, and robust and universal filament. | ||
| Strain Sensing | Key characteristics of strain sensor types include: Fewer lobing errors, long operating life, extremely versatile, wide operating speed range, long stylus carrying and ideal for peck, or stitch scanning. | ||
| Piezoelectric | Key characteristics of piezoelectric sensor types include: Very few lobing errors, large stylus-carrying capability, multi-mode sensor operating extend versatility, and restricted operating-speed range. | ||
| LVDT (Linear Variable Differential Transformer) | Key characteristics of LVDT or linear variable-differential transformer sensor types include: High accuracy and large stylus carrying capacity. | ||
| Optoelectronic | Key characteristics of optoelectronic sensor types include: High accuracy than kinematic types and high data rates. | ||
| Laser Triangulation | Key characteristics of laser triangulation sensor types include: Single axis profile measurement and the laser may be reflected by surface reflectivity. | ||
| Capacitive | Key characteristics of capacitive sensor types include: Alternative noncontact technology, profile, form and surface flaw measurement may be affected by material type or surface chemistry and uses a fixed stylus. | ||
| Video Imaging | Key characteristics of video imaging sensor types include: Suitable for 2-D and flexible parts, automatic edge detection possible, and may be affected by surface reflectivity and ambient light. | ||
| Other | Other unlisted sensor type. | ||
