F317 High Performance Fatigue Rated Cylindrical Loadcell
A high slenderness ratio strain section improves all round performance compared to the older design F204. New thread sizes are employed offering more economic sizing of rod end bearings and improved availability. Novatech can supply suitable rod ends.
The industry standard fatigue rated loadcell has traditionally been the pancake loadcell, our F254 is a typical example. By restricting the nominal output to a safe strain region the cylindrical loadcell offers the same number of full load reverse cycles as a minimum life expectancy. The cylindrical form offers the advantage of a reduced diameter, often advantageous in actuator applications. Adaptors are not required which are costly and add mechanical interfaces to the load train assembly.
We are happy to design variants of this loadcell to meet your specific requirements. Versions can be manufactured for fully compensated operation up to +250°C. Please consult our engineering department.

Notes
- AL = Applied load.
- RL = Rated load.
- Temperature coefficients apply over the compensated range.
- The load must be applied directly through the central loading axis.
- AO = Average of tension and compression outputs for full load.
Connections
The ranges above 5kN are fitted with 2 metres of PVC insulated 4 core screened cable type 16-2-4C or a 4 pin Binder 723 series chassis plug. The 5kN range is fitted with 2 metres of PVC insulated 4 core screened cable type 7-2-4C, the connector option is not available on this range.
Excitation + = Red or pin 1, Excitation – = Blue or pin 2, Signal + = Yellow or pin 3, Signal – = Green or pin 4, Screen = Orange.
Reverse the signal connections to obtain a positive signal in tension mode. The screen is not connected to the loadcell body.
