TC4

Bi-Directional Pancake Load Cell

CAPACITY
250KG – 500TF

NON-LINEARITY
0.05%RO

RATING
IP67

The TC4 bi-directional pancake load cell is a low-profile device for tension and compression measurement during static or dynamic testing. 


With a fully laser welded, stainless steel assembly, the TC4 load cell offers high resilience to wear and tear, as well as IP67 sealing. 

In addition, the TC4 is rated to ISO 376 Class 1, making it ideally suited for test rig applications. 


For the full product specification and a complete list of options/accessories available, please download the product datasheet.


Should the TC4 not quite suit your requirement, the PLC load cell may be of interest, as its design can be customised – please refer to the PLC datasheet for more information.

(1) The 0.25tf TC4 load cell is not available with built-in amplified output. (2) The 300tf and 500tf rated TC4 load cells are guaranteed in tension up to 250tf only. (3) Tests and calibrations performed in compression with the load cell mounted on a bearing support with correctly tightened clamping screws. (4) Percentage errors referred to reading, min. 1/10 of nominal load. (5) The dynamic load must be applied to the load cell central thread and not to the external fixing rim. (6) As standard the 200-500tf rated TC4 load cells are supplied fitted with a MIL7M connector with mating 5m cable.
