SupplyWhat impact will the jumping of the object being measured in Huangshi he on the data display of the diameter gauge?
Key words: Diameter gauge optimization, diameter gauge runout, runout of the measured object, vibration elimination technology
Regarding the issue of the object being measured by the diameter gauge jumping out of the measurement area, the following is a detailed technical analysis:
1) Measurement failure situation: When the object being measured jumps beyond the measurement area, the diameter gauge will exhibit the following phenomena:
The photoelectric conversion element cannot fully capture the shadow of the object being measured. (The JG01-DG140 diameter gauge adopts the dual-tube parallel light measurement technology. Exceeding the field of view will result in the loss of L1/L2 width data.)
The system may display the error code "ERR" or trigger an over-limit alarm
Specific impact manifestations
2) Data anomaly:
The measured value suddenly returns to zero or shows the maximum value (for example, a 150mm range device may display 150.00)
Ellipticity calculation failed (the size difference between A1 and A2 of the dual-probe model exceeded the system tolerance)
3) Equipment reaction:
The red light alarm is on (safety warning in compliance with IEC standards)
• RS485 communication interruption (packet loss rate may reach 100%)
The industrial control computer records the "out-of-range" event log (with timestamps accurate to milliseconds).
4) Technical solutions
(1) Hardware adjustment
Install the guide rail limit device (it is recommended to lee a 5mm safety margin)
Switch to adjustable-pitch probes (for custom models, the range can be doubled).
Youdaoplaceholder2 Add auxiliary positioning rollers (reduce random runout within ±2mm)
(2) Parameter Optimization
Adjust the electronic shutter speed to 1/10,000 second (to deal with high-frequency vibration)
Enable multi-channel synchronization technology (error Set the software filter window (5-point moving erage is recommended)
5) Special case handling: For continuous jumping conditions, it is recommended to:
• Give priority to the JG02-DG series dual-channel equipment (with built-in anti-jitter algorithm)
Install an air bearing stabilizer in the measurement area (which can control the runout within ±0.5μm)
The installation method adopts carbon steel frame + height-adjustable lead screw (with a 40% increase in rigidity)
Note: The Z-axis dynamic range of a standard single-channel diameter gauge is typically 1mm (0.3mm for portable models). When the fluctuation of the object being measured exceeds this range, it is necessary to consider upgrading to a rotary diameter gauge (with a measurement range of up to 50mm).
