ABSTRACT:
A system for measuring the flexure of a saw blade in situ includes in one embodiment a non-contact displacement sensor and means for directing a fluid flow at the blade adjacent the sensor. The deflection of the blade by the fluid flow is detected by the sensor which generates a signal related to blade flexure. The system indicates when a saw blade is correctly tensioned or when retensioning is required.
