nnCompression force transducers For level measuring with electrical output nn

Description Features

With this hydraulic/electric force transducer, forces (weights) are picked up in a simple, cheap manner and made available directly for further processing by means of an analogue output signal. The force measuring unit works on the hydraulic principle. The force applied to the piston is converted into a hydraulic force depending on the piston area and transmitted to the integrated measuring cell. The analogue signal output is 4 ... 20 mA. The analogue signal can be processed and displayed in different units e.g. N, kN, kg, with a digital display that has a micro-processor. The piston stroke is 0.5 mm max. With this force transducer the piston is so designed that it is matched to the face of the force transmitting piston up to about 3Ѱ. An exact force measurement requires a force that is concentric and at right angles to the piston. Moreover the piston must be free of side forces. This force transducer is not suitable or only suitable under certain conditions for the measurement of impact energy or acceleration. Providing the frequency is not too high, increasing and decreasing forces can also be measured with hydraulic force transducers. With a view to the life of the force measuring unit, a force measuring unit with a somewhat larger working range should be chosen.
