Hydraulic load cells are mainly used in static applications. The increased force time (referred to the rated load) should remain constant for at least 1 second. Continuous rapid changes in force may destroy the pressure gauge. It can however be protected against shock loads arising when the load is applied or removed by means of appropriate throttles. All load cells are made of stainless steel.
Instrument for force measurement in connection with DMS force transducers, including integrated mains supply.
These force measuring devices are suitable for universal applications, namely wherever tensile and pressure forces need to be measured with a high degree of accuracy, e.g. in materials testing (Erichsen Tensile Testing Machines UNIMAT® and UNIMAT® + UNICONTROL ®), in reference measuring equipment and in research and development. For industrial purposes too, these force transducers are ideal in the fields of automation, controlling press-in processes and in jointing technology. An extensive accessories program is available. A connection to the Measuring and Display Instruments 975 AP, 980 AP and PHYSIMETER 906 MC is also possible by means of an adapter plug. Measuring range 5kN to 1000kN available.
The Measuring System PHYSIMETER 906 USB is used for the acquisition of mechanical parameters based on wire strain gauge sensors. The ergonomically designed housing made of anodized, high-strength aluminum, is provided with threaded bores at the front side so that an unproblematic connection to the ERICHSEN testing machines is guaranteed – as it was also the case with the preceding models of tensile and pressure measuring devices. As an option a calibration according to VDI/VDE 2624 sheet 2.1 – Measurement of mechanical quantities – Instructions for calibration of mobile force measurement systems – is available. With integrated or external force sensor and USB interface.

The special feature of Model 146-60 & Model 146-100 are the increased drawing speeds of the drawing punch which, in addition to the normal drawing speed range that can be adjusted, in an infinitely variable manner and independent of load. This is achieved by using a separate oil circuit, fed by a pump with high volumetric displacement. Contrary to the high speed attachment based on a nitrogen accumulator, here a constant drawing speed behaviour is guaranteed over the total displacement of 150 mm. As to the technical design and the options available, including PC control and proportional valve technique, this machines are similar to Models 145.
