Force Transducer/Impact Hammer Type 8203 is a unique structural testing kit designed for use with lightweight and delicate structures. The force transducer measures the force applied to the structure. It can be connected to the hammer kit for impact testing or to a small exciter (for example, Brüel & Kjær Type 4810) via the stinger kit provided.

Uses

* Dynamic and impact-force measurements on small structures
* Measurement of frequency response functions using both impact and continuous excitation techniques
* As part of a dynamic structural testing system for modal analysis and the prediction of structural response

Features

* Compact size and low weight allied with an all-welded, robust construction
* Good linearity
* Excellent, long-term stability due to artificial aging
* Individually calibrated and easily mounted
* Easily attached to the stinger and hammer kits
* Negligible changes to dynamic properties of test structure
* Comes with all necessary accessories for every type of mounting
* Titanium tip seating to minimise lateral deformation of tip material during impact
* Aluminium shaft to reduce occurence of double impact
* Charge mode (PE) output

Force Transducer

The piezoelectric force transducer is designed to measure dynamic and impact forces. It is pre-loaded to precisely 1 000 N, allowing compressive force measurements of up to 1 000 N and tensile force measurements of up to 250 N. The transducer is mounted on the test structure so that the force to be measured is transmitted through the transducer. When used with an exciter, the transducer signal can be used to measure and control the applied force. The frequency response function of the test structure can be measured by using a dual-channel analyzer. The force transducer is used to measure the input force and an accelerometer (or laser velocity transducer) is used to measure the response of the structure.
