Vibration Calibrators

Product catalog summary
Overview
This document provides technical specifications and applications for vibration calibrators, specifically models VC20, VC21, and VC21D, used for calibrating vibration transducers and measuring systems.

Applications
  • Rapid calibration of vibration transducers for acceleration, velocity, and displacement.
  • Fault detection in vibration measuring systems.
  • Low-frequency calibration for whole-body and building vibrations according to ISO 8041 and DIN 4150-3 standards using VC21.

Key Features
  • Load-independent amplitude for test objects up to 600 grams.
  • Vibration magnitude options: 10 m/s² for VC20; selectable from 1 to 20 m/s² for VC21.
  • Quartz-controlled frequency: 159.15 Hz for VC20; adjustable from 15.92 Hz to 1280 Hz for VC21.
  • Display includes frequency, magnitude, error percentage, and calibration date.
  • VC21D features detachable device for dynamic calibration and clock output for synchronization.
  • Traceable to national PTB standard with included factory calibration certificate.
  • Rugged design suitable for laboratory and field use with mains buffered battery operation.

Technical Data
  • Vibration frequencies range from 15.92 Hz to 1280 Hz.
  • Vibration accelerations range from 1 m/s² to 20 m/s².
  • Maximum test object weight varies with vibration magnitude.
  • Amplitude error: 3% (0-40°C) and ±5% (-10-55°C).
  • Frequency error: ±0.05%.
  • Operating temperature range: -10 to 55°C.
  • Battery type: built-in NiMH, 7.2 V / 1.6 Ah, with approx. 5 hours operating time per charge.
  • Charging time: approx. 4 hours.
  • Automatic switch-off: 10 minutes, adjustable up to 30 minutes.
  • Dimensions: 100 x 100 x 120 mm; Weight: 2.2 kg.

Accessories
  • Includes a plastic carrying case, mains plug adapter, and thread adapters.
  • Optional thread adapters available for VC21D.
