Calculation of the compensating torque when using an extension
A torque wrench is typically adjusted and calibrated by applying a known force at the center of the handle at a distance L1 from the center of the driving square.
In some applications it is necessary to add an extension to the wrench, especially when some work has to be carried out in confined areas. In such cases it is necessary to compensate for this extension by reducing the program- med set torque on the wrench according to following formula:
C = L1 x T
L1 + B
L1= Distance from above table
B= Length of extension
T= Required torque
C= Compensated torque
L1= | 335 mm |
|
|
|
B = | 40 mm |
|
|
|
T = | 20Nm |
|
|
|
C = | ? |
|
|
|
C = | 0.335 x 20 | = | 6.7 | = 17.86 |
0.335 + 0.040 | 0.375 |
C = 17.86 Nm (18 Nm)
