Industrial Applications

1. Automotive Precision Machining Quality Control

In automotive component manufacturing, parts like engine pistons and shafts must be measured directly on the production floor where cutting fluid and coolant spray are present. Utilizing the IP67-rated 264-622 transmitter mounted on a coolant-proof micrometer allows operators to take measurements near active CNC machinery and wirelessly transmit data to a centralized PC up to 20 meters away.

Problem Solved

Eliminates the physical risk of cable damage and liquid ingress into measurement electronics, while removing manual entry errors in oily environments.

2. Aerospace Structural Component Measurement

In aerospace assembly lines, large structural parts require multiple dimensional checks at various hard-to-reach locations. The lightweight (18 g) and compact (4.19 x 3.88 x 1.29 cm) transmitter allows operators to perform measurements without being tethered by long cables, transmitting data instantly upon button press.

Problem Solved

Eliminates physical restrictions and safety hazards caused by long, dangling SPC cables around large structures, scaffolds, and ladders.

3. High-Throughput Quality Assurance Inspection Stations

Quality control stations measuring high volumes of machined parts can integrate the 264-622 transmitter with their micrometers to feed measurement data directly into SPC programs like Mitutoyo MeasurLink or Microsoft Excel. Each transmission is confirmed immediately by the LED indicator.

Problem Solved

Reduces inspection cycle times by eliminating manual logging of values, avoiding transposition errors, and ensuring high-speed data flow (250 kbps) for continuous batch inspection.
