The KEYENCE WM-C3000 camera unit and WM-P3000 wireless probe form the core of the WM-3000 series, a wide-area coordinate measuring system designed for large-scale parts that cannot be easily moved to a traditional CMM. Unlike fixed gantry systems, this configuration uses optical tracking to locate a handheld probe in space, enabling measurement across volumes far exceeding conventional equipment.
System Architecture
The WM-3000 system consists of two primary components working in tandem. The WM-C3000 camera unit serves as the optical tracking head, capturing the position of the wireless probe within its field of view. The WM-P3000 probe is a handheld, battery-powered unit that the operator uses to touch measurement points on the workpiece. This separation of tracking and probing functions allows the measurement volume to be scaled simply by relocating the camera unit.
WM-C3000 Camera Unit Specifications
Parameter Specification
Maximum Measurement Length 10,000 × 3,500 × 5,000 mm (W × D × H)
Accuracy-Guaranteed Range 3,000 × 1,500 × 1,500 mm
Indication Error Accuracy ±(28 + 5L/1000) µm (within guaranteed range, at 23 ±1°C)
Repeatability (2σ) ±10 µm
Minimum Display Unit 0.001 mm (distance) / 0.001° (angle)
Camera Rotation θ: ±90°, Tilt: ±30°
Communication: Bluetooth 5.0, USB 3.0, Infrared 945 nm
Power Supply: 24 VDC via dedicated AC adapter, 1.7 A
Dimensions 327.7 × 250.9 × 357.3 mm
Weight: Approx. 13 kg
The camera unit’s ability to rotate ±90° in theta and ±30° in tilt provides flexibility in positioning the tracking head relative to the workpiece, accommodating setups where direct line-of-sight might otherwise be obstructed.
WM-P3000 Wireless Probe Specifications
The handheld probe operates wirelessly via Bluetooth 5, communicating with the camera unit to relay measurement points in real time.
Parameter Specification
Markers: 7 markers, 870 nm light source
Applicable Stylus M5
Display: 2.7-inch transmissive TFT color LCD, 240 × 320 pixels, analog resistive touch panel
Hard Keys: MEASURE, OK, CANCEL, POWER
Communication: Bluetooth 5, USB 2.0, Infrared 945 nm
Battery: Dedicated lithium-ion pack, 3250 mAh
Charging Time: 6.5 hours
Continuous Usage: Approx. 8 hours
Weight Approx. 600 g (with battery)
The 2.7-inch color display on the probe itself allows the operator to view measurement results, confirm points, and navigate menus without returning to a PC workstation. The M5 stylus thread accepts standard styli, providing compatibility with common probing accessories.
Operational Characteristics
The system operates within an ambient temperature range of +10°C to +35°C and relative humidity of 20–80% RH (no condensation) for both components. Accuracy specifications are guaranteed within the 3,000 × 1,500 × 1,500 mm range at a controlled temperature of 23 ±1°C. For measurements outside this guaranteed range but within the maximum measurement length, the system remains functional, though accuracy should be verified against application requirements.
The WM-C3000 connects to a PC via USB 3.0 for data transfer to KEYENCE WM measurement software, which supports CAD comparison, GD&T analysis, and inspection reporting.
Practical Applications
This configuration is suited for measuring large assemblies, fixtures, molds, and parts that are difficult or impractical to transport to a fixed CMM. Typical use cases include:
In-process verification of large machined components on the shop floor
Fixture and tooling validation where setup dimensions must be confirmed in place
Reverse engineering of legacy parts lacking documentation.
First-article inspection of large castings or fabrications
The wireless probe design allows the operator to move freely around the workpiece without cable management concerns, while the optical tracking approach eliminates the need for a granite table or precision guideways.
