  • Page 6: For Your Safety

    Property damage to the equipment or the surroundings will result if the hazard is not avoided. Hinweis: It is important to heed these safety notices in order to ensure you handle the model 8427 tension and compression load cell correctly.

  • Page 7: Introduction

    Intended use The load cells in the 8427 model series are primarily designed for the measurement of force in production equipment, using newtons (N) as the unit of measurement. The local gravitational acceleration (g ≈ 9.81 m/s²) must be taken into account when determining masses. Customer service 2.1.1 Customer service department...

  • Page 8: Storage

    EN 61558. 2.3.3 Restrictions on use The model 8427 tension and compression load cell does not pose a hazard if used within its specification and in accordance with the safety regulations.

  • Page 9: Personnel

    Only ever use the model 8427 tension and compression load cell under the conditions specified in this operating manual. Inspect the model 8427 tension and compression load cell for damage. If you suspect that the device has been damaged during shipping, notify the delivery company within 72 hours.

    Concept and general information Please refer to the data sheet for the model 8427 precision tension and compression load cell for full details of dimensions, weight, degree of protection etc. Mechanical design In the model 8427 tension and compression load cell, the spring element is designed as a horizontally oriented elastic membrane with a centrally arranged ring.

  • Page 12: Strain Gage Wiring

    : Reference excitation voltage • c: Rated output of the load cell You can find the rated output “c” on the test certificate for the model 8427 tension and compression load cell. It is typically in the region of approx. 1.1 mV.

  • Page 13: External Forces

    EN 61558. Hinweis: Transmitters connected to the outputs or other devices that are galvanically connected to the signal lines of the model 8427 tension and compression load cell must also be fitted with safety transformers to EN 61558.

  • Page 14: Installation

    WICHTIG: Prevent torsional moments, lateral forces and bending forces. Application of force 1. Apply the force being measured to the model 8427 tension and compression load cell via the central thread. 2. Apply the force centrically exactly along the axis of symmetry.
  • Page 15 You can recognize an overload from an increased output signal at no load. Bending plates are relatively insensitive to overloading. Hinweis: Check the model 8427 tension and compression load cell if the signal increases by more than approx. 5 %...

  • Page 16: Fixing Method

    Fixing method The entire contact surface of the model 8427 tension and compression load cell must lie on a hardened (min. 58 HRC), flat, ground or lapped mounting surface. The load cell is designed for universal use with a wide range of fixing options.
