Model Identifier VDS-P30
Official Part Number 571-253-20
GTIN Standard 4946368599748

Technical Overview

IP67 coolant-proof absolute digital depth gauge with 0-300mm range, ±0.03mm accuracy, and SPC data output. Features hardened stainless steel micro-lapped base.

Key Features

  • ABSOLUTE electrostatic capacitance linear encoder automatically retains the established origin point for the life of the battery.
  • IP67 environmental protection rating provides superior coolant-proof, water-proof, and dust-proof reliability on the factory floor.
  • Constructed of hardened stainless steel with micro-lapped reference base and measuring faces for exceptional wear resistance.
  • Built-in SPC digital data output facilitates real-time data collection and integration into quality control management networks.
  • Large, high-contrast LCD display with 11 mm character height ensures quick and error-free measurement readings.
  • Supports optional wider extension base attachments to accommodate large-span measuring configurations.

Powered by a single SR44 silver oxide battery (Part No. 938882) with an exceptional battery life of approximately 5 years (20,000 hours) under normal use. Features a automatic power-saving shutoff after 20 minutes of non-use and a low-voltage battery alarm.

Industrial Applications

1. Automotive Cylinder Deck and Bore Depth Inspection

Utilized directly on the CNC machine bed for verifying cylinder counterbore depths and deck-face steps on engine blocks. The IP67 rating ensures the gauge remains impervious to splashing cutting oils and cast-iron dust.

Problem Solved

Eliminates the time-consuming process of cleaning coolant from components before measurement, avoiding tool malfunction and maintaining production throughput.

2. Aerospace Panel Pocket Metrology

Measures deep pocket milled recesses in aircraft skin panels to ensure weight-saving geometries are strictly within design tolerances (0 to 300 mm). The hardened and micro-lapped base ensures a perfectly flat reference against panel faces.

Problem Solved

Replaces unreliable manual depth inspections and provides a digital audit trail via SPC output to satisfy strict aerospace documentation standards.

3. Die and Mold Cavity Verification

Ideal for inspecting deep cavities and multi-stepped cores during plastic injection mold making. The ABSOLUTE linear encoder prevents slider overspeed errors and operates smoothly over the entire 300 mm range with 0.01 mm repeatability.

Problem Solved

Prevents measurement drift and calibration errors caused by frequent, manual zero-point resets between different mold cavities.
