Richiedi un preventivo

Accelerometer Calibrator Type 4294 permits accurate adjustment of measuring instrumentation at a standard acceleration level of 10 ms–2 (0 – 70 g load).

The reference signal may additionally be used for velocity and displacement calibration, at 10 mms–1 and 10 µm respectively.

USE SCENARIOS

  • Rapid calibration and checking
  • Quick, easy field calibration of vibration measurement and recording systems

FEATURES

  • Small, lightweight, and battery-driven
  • Leather case for impact protection
  • Designed for everyday use in harsh environments
  • Acceleration, velocity and displacement calibration
  • High-precision, crystal-controlled servo operating at 159.15 Hz (1000 rad s–1)

  • Splash-proof according to IP 54 (IEC 60529)

The calibrator embodies an electromagnetic exciter driven by a crystal oscillator at a frequency of 159.15 Hz (1000 rad s–1). Servo feedback via a small accelerometer on the underside of the vibration table is used to maintain a constant and accurate vibration level - independent of the mass of the transducer under test.

Use of the calibrator is very straightforward. The transducer is conveniently attached to the calibrator table using a 10–32 UNF Steel Stud (YQ-2962).
