Description
Model F1145 Hydraulic compression force transducer
Compact version up to 850 kN
The hydraulic compression force transducer model F1145 is available with a nominal size NS 141. Measurement of rated forces from 6 up to 850 kN is possible. The robust mechanical design enables use in harsh operating conditions. Applications for this hydraulic force measurement can be found in equipment manufacturing, in device and special machine building and also with measuring and control systems.
Hydraulic force transducers operate on the principle that the force acting on the piston is converted into a hydraulic pressure – in proportion to the piston surface area.
Via the connected measuring instrument, which can be either analogue or digital, the measured value is output. The scale of the connected pressure gauge can be defined in various units, e.g., in N, kN, kg, or even t.
Leak-tightness warranty
The warranty on leak tightness of the hydraulic force measuring unit was extended to 5 years. A force transducer that starts to leak within this period will be repaired free of charge.
Use of the force measuring unit as intended is a prerequisite for the extended 5-year warranty.
