This series of fatigue rated load cells brings a dynamic dimension to force measurement from 250 N to 2500 kN.
During tests carried out on servohydraulic machines, elements of the system are subject to acceleration. As a result, and in addition to the force applied to the specimen, the load cell reads forces resulting from its own movement or vibrations and the mass of the grips and fixtures attached to it. This causes error between the required force and the actual force.
Dynacell introduces the following advantages:
- Reduces dynamic load errors, which can be a significant percentage of reading
- Increases productivity by allowing higher frequency operation while maintaining test validity - improvements such as doubling the frequency are common
- Provides an improved closed-loop load control for higher frequency testing
- When used with Instron's 8800 digital controller, it allows automatic set up of inertia compensation, reducing operator errors, and improving system integrity
Dynacell Solution
The Dynacell load cell minimizes errors from inertial loads by using an accelerometer that is right at the heart of the load cell, directly on the load axis. The conditioning of the acceleration signal from the Dynacell is handled as standard in the digital 8800 electronics and is set-up automatically when the system is auto-tuned.
