The hydraulic force transducer model F1122, version NS 3 x 33, is suited for regular testing of the clamping force in 3-jaw chucks. It thereby ensures optimum use of the clamping jaws.

Hydraulic force measurement is a simple way to capture and display the forces occurring in various applications.


The force is measured using the principle of hydraulics: The force acting on a piston leads to a pressure increase that can be visualised on a connected display instrument. The scale of the display instrument can be defined in various units (e.g. N, kN, kg, t).

Leak-tightness warranty
The warranty on leak tightness of the hydraulic force measuring unit was extended to 5 years2). A force transducer that starts to leak within this period will be repaired free of charge.

1) For rated loads below 500 N, the accuracy is ±1.6 % Fnom for all connected measuring instruments.
2) Use of the force measuring unit as intended is a prerequisite for the extended 5-year warranty.
