PullTester 28

Pull Testing Machine

Schleuniger’s PullTester 28 is a dual-range, motorized benchtop device designed to measure pull forces of wire crimp connections as well as ultrasonic metal welding connections on a wider range of wire than single-range pull test devices. The PullTester 28 is specially suited for quality assurance in a production environment.

  • Dual LCD displays for simple programming and operation
  • Speed -controlled motor provides extremely consistent readings
  • 3 pulling modes for destructive & non-destructive tests
  • Simple LCD display for easy programming and read out
  • Standard RS 232 interface for curve analysis and downloading test data
  • Networking capabilities (optional)
  • Dual range for improved accuracy over a wider range of wires
  • Two versions available
  • Four selectable pulling rates
  • Memory for up to 2,400 values

Pull test values are critical parameters for quality control and assurance. The PullTester 28 can also perform non-destructive tests (hold to a specified force). This versatile machine has two versions with two measuring ranges each, which are individually calibrated enabling use for small or large cables.

  • PullTester 28 (standard): 2,000 / 5,000 N (440 / 1,100 lbf.)
  • PullTester 28-10 (special): 5,000 / 10,000 N (1,100 / 2,200 lbf.)

This dual-range capability ensures the highest accuracy for the widest range of applications. Hand actuated or pneumatic pull test devices can give inconsistent data depending on the operator or pull rate. Some standards specify that a test device must pull with a consistent rate. The Schleuniger PullTester 28 is equipped with a speed-controlled motor, ensuring consistent pull rates throughout the measuring range resulting in repeatable and accurate data. Pull forces can be measured in poundforce, Newtons or kiloponds. The terminal holder can be designed and manufactured based on your application. In addition, a variety of terminal holders are available upon request.
