The model F6154 hydraulic ring force transducer in heavy-duty design enables the measurement and display of forces in harsh environmental conditions. Its measuring ranges from 25 kN to 1,500 kN. Applications for hydraulic force measurement can be found in equipment manufacturing, in geotechnology and specialist foundation engineering, in device and special machine building and also with measurement and control systems.

The connection of the display instrument can, optionally, be made using a capillary or measuring hose. This enables the convenient reading of the measured value. Furthermore, the measuring hose offers the possibility of “separation without any losses”, which enables an exchange of the display instrument without the need for dismounting the force measuring unit.


Hydraulic force measurement makes use of a piston-case combination with different seals as a sensor unit. The force acting is the product of the area and the pressure. For the display of the pressure, either pressure gauges, pressure sensors or pressure measuring instruments with contact devices can be used. The scale of the display instrument can be defined in various units, e.g., in 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 forces below 500 N, the relative linearity error 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.
