Piezoelectric Force Transducers

Brüel & Kjær force transducers provide integral electronics designed for dynamic, short-duration static and impact force measurements. The transducers are typically used for measuring applied forces in modal applications. As an example, they are inserted between an exciter and a test structure, or as a for general-purpose instrument to measure force within process applications.

The ultimate goal of using a force sensor is to measure the input force of an accelerometer (or laser velocity transducer), in test scenarios where you want to measure the impulse, or impact force response of a structure.

Characteristics

The transducers work on the piezoelectric effect of quartz. When stressed, or compressed, this provides an electrical charge proportional to the compressing force. The charge is converted to a low-impedance voltage output and the sensitivity is therefore expressed in terms of voltage per unit force (mV/N).

The housing material is stainless steel giving a very stiff and rigid construction. The transducers are mounted using the 28 UNF tapped holes on the top and bottom of the body, and feature a 10 - 32 UNF side connector.

Calibration of the Force Sensitivity

The transducers are supplied with an individual calibration of the force sensitivity.

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 then be measured and analysed using a stationary or hand-held dual-channel analyzer.

As an example, the force sensitivity for the transducer family type 8230 is listed below:

Type 8230 has a sensitivity of 110 mV/N (500 mV/lbf).
Type 8230-001 has a sensitivity of 22 mV/N (100 mV/lbf).
Type 8230-002 has a sensitivity of 2.2 mV/N (10 mV/lbf).
Type 8230-003 has a sensitivity of 0.2 mV/N (1 mV/lbf).
