Compressive force sensors - Import export

The force measuring chain is an 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 DAkks calibration certificate is included so that the force measuring chain can be traced back. The calibration is traceable through accreditation at the German Accreditation Body. The calibration certificate records the displayed values for mounting positions at 0°, 120° and 240°. During calibration in field, 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).

This miniature force sensor was optimised with respect to its height and is, at only 3.4 mm, the lowest known sensor with strain gage technology. Hardly higher than the diameter of its connection cable, it can also be housed in conditions where space is limited. Along with its minimal geometry, the force sensor is also particularly light. It has a high resonance frequency to follow quickly changing load alternations. Despite its extreme miniaturisation, in its application it remains completely robust and suitable for industry, not only with regard to the highly flexible cable connections or the full welding of sensors for the measurement ranges ≥ 0 … 10 N. The miniature compression force sensors are flat, cylindrical discs with covered bottoms. The central load application button for taking on compression forces is an integrated part of the top, which is the sensor‘s membrane.

Inductive displacement sensors of this series measure linear displacements and indirectly all mechanical values convertible into displacements by additional equipment (i.e. tension and compression forces, extension, torque, vibration). The sensor body equipped with a connector has an outer diameter of only 8 mm and therefore is especially well suitable for the integration in dimensionally restricted structures. Typical application fields are displacement and extension measurements on: —Machines —Servo systems —Motor vehicles —Test benches —Production plants The cylindrical case made of stainless steel, houses a differential transformer (LVDT). It consists of a primary and two secondary coils with axially moveable core. A displacement of this core changes the magnetic induction of the coils. The INLINE carrier frequency amplifier converts the displacement into a direct proportional electrical DC voltage.

Standard reference force transducers specially designed according to the ISO 376 standard (classes 1, 0,5 and 00). o Wide range of capacities (up to 50 MN) Complete range of load accessories o Tension and / or compression (universal)

The small dimensions of the hydraulic force transducers of the model series TesT 1001 / 1011 / 1021 as well as the flat building method permit versatile applications. The small transducers were conceived for occasional control measurements, e.g. for adjusting or service work. The indicating instruments of model versions 1001 and 1011 have a diameter of 63 mm. The indicating instrument of model version 1021 can have a diameter of 63 mm or 100 mm. All model versions possess a drag indicator to display peak values.
