A force measuring instrument generally consists of a sensor and a display on which the result of the measurement is output in the form of a numerical value with the associated unit. A force measuring instrument thus consists of a force transducer and a display on which the measured force can be read. Since a force measuring instrument combines the measuring component and the display unit in one, mobile use is particularly frequent. Three types of force measuring instruments are described in more detail in the WIKA portfolio: the FRKPS chain hoist test set, the FSK01 welding tongs test set and the hydraulic force measuring instruments, which operate without any electricity. They are all easy to use and guarantee high process reliability through the quick monitoring of the important values.
