Displacement Sensor Model 8740, 8741 - 5

Technical Product Information Commissioning, Function, Fitting Specifications Design of the linear differential transformer The linear differential transformer is composed of a primary coil and two secondary coils. The secondary coils are positioned symmetrically about the primary coil and connected in opposition (see Fig.1). A moveable ferromagnetic core in the form of a sliding shaft is located inside these coils. secondary coils moveable sliding shaft primary coil Schematic of the linear differential-transformer (LVDT) How the differential transformer works As the ferromagnetic core...

Displacement Sensor Model 8740, 8741 - 6

Technical Product Information Commissioning, Function, Fitting Specifications Model 8739, 8740, 8741 Avoid lateral movements or forces. The displacement to be measured must lie along the axis of symmetry. The mount used to hold the sensor in place (clamping collar, mounting sleeve or the like) affects the sensor sensitivity. It introduces additional magnetic damping, which alters the symmetry of the internal magnetic field.  Always check the material used in the fitting elements and select a suitable type of fixture. Only use fitting elements that are made of a non-ferromagnetic material....

Technical Product Information Commissioning, Function, Fitting Specifications Hand-tighten the clamping screw on the bracket. 8739 with angle bracket Note: If you use two fixing brackets, both brackets must be made of the same material. Only use fixing brackets that are made of a non-ferromagnetic material (we recommend brass, aluminum or plastic). Both brackets must fix the sensor in the same manner. Only hand-tighten the fixing screw on the bracket. Mounting model 8740 or model 8741  Use one of the following mounting blocks to mount the model 8740 and 8741 sensors:  8740-Z002 ...

Technical Product Information Commissioning, Function, Fitting Specifications Model 8739, 8740, 8741 Note: If you install several sensors close together, the alternating fields of these sensors may influence each other. Isolate every sensor from each other using covers with adequate thickness. Circumstances vary for each particular measurement setup. Hence the circuit diagram (Figure 6:) should be viewed as an example only. connected only at 8739 Shield brown (+ excitation) green (+ signal) white (- excitation, - signal) Note: For model 8739 displacement sensors, you can disconnect the...

Displacement Sensor Model 8740, 8741 - 10

Technical Product Information Commissioning, Function, Fitting Specifications Adjustment with a physical magnitude Function The sensor is subjected to a known physical magnitude. In this way, the calibration is carried out over the entire measuring chain, consisting of the sensor and display device or amplifier. Remove any load from the sensor. Load the sensor with a known reference weight. Adjust the reference scale value. If desired, we can prepare factory calibration or recalibration certificates for the sensor or for the entire measuring chain. These measurements are carried out at the...
