“…For each weight, a value corresponding to the deformation of the strain gauges (µm / m) was recorded by means of Spider and the "Catman-EASY" software application. With help of the IMADA ZP500N and ZP5N force transducers and the "ZP Recorder" software application, the second calibration solution entitled (B) was developed [4]. This calibration consisted in programming the IMADA force transducer, in order to apply forces between 0.1 N and 1.4 N on the lamellar springs, and the result can be read with the help of the Spider acquisition system and the software application "Catman-EASY .…”

The paper aims to design and develop force transducers for industrial environments to cover different values (ranges) of the measuring force. The calibration of the leaf springs was performed using two experimental methods. The first solution entitled (A) was to apply to the springs a force with a number of different calibrated weights. Based on the IMADA ZP500N and ZP5N force transducers and the "ZP Recorder" software application, the second calibration solution entitled (B), was developed by authors. The paper briefly presents the steps taken into account to obtain the force transducers. Processing of the leaf springs, cleaning the surfaces where the strain gauges are to be glued, protecting the strain gauges and finally gluing the terminals of strain gauges for connection to the Catman interface are presented. Calibration of force transducers was performed for different shapes of lamellar springs: rectangular, triangular, trapezoidal. The experimental results for each force transducer were processed using Matlab environment. The best behavior in terms of the characteristics of the transducers is the triangular lamellar spring transducer. Two materials were considered for the lamellar springs: steel and bronze. Depending on the force field to be measured, one material or another is chosen. An important requirement for the operation of these transducers is not to exceed the range of forces for which it was designed.
