Application

The force measuring chain is a universal reference measuring chain for the calibration of press-fit force measuring equipment. It finds applications in the quality assurance, commissioning and equipment monitoring fields. A DKD calibration certificate is included so that the force measuring chain can be traced back. The calibration is traceable through accreditation at the PTB (German national metrology institute). The calibration certificate records the display figures for mounting positions at 0°, 120° and 240°.

During on-site calibration, the reference load cell is inserted in line with the flux of the press-fit measuring equipment. The force application is of central significance here for the quality of the measurement. Special force application parts are required, so that the line of action of the force agrees as exactly as possible with the geometrical axis of the load cell that is to be measured (central loading). It is, furthermore, very important that neither transverse forces nor torques reach the load cell.

When load cells have to be changed frequently, user-friendly software provides a facility for quickly and simply carrying out device configurations and backups. This allows the sensor and device data to be called back at any time without difficulty.

Description

The digital display in the model 9180 desktop housing supports load cells based on strain gauges. The value presently being measured is displayed on the 14 mm-high main LED display, while the peak value, for instance, can be read on a second display immediately underneath. Thanks to the low measuring errors, the indicator is particularly suitable where high accuracy is required. The tare function allows any base load that may be present to be cancelled out. The force measuring chain consists of a model 9180 measuring instrument and the 8527 load cell and can be used to measure compressive forces up to 100 kN (depending on the force range). With the help of the fastening holes located around the circumference and of the undulation on the engaging surface, the sensor can relatively easily be adapted to existing manufacturing and production systems. Depending on the existing compression force, the user can select a measuring range from 500 N up to 100 kN (in 8 stages).

The reference measuring chain is fully conigured and calibrated. The DKD calibration accords with EN ISO 376.
