What special considerations should I take to properly integrate and mount my 2222C transducer to get the best results?
The 2222C is a light weight, high g, Piezoelectric transducer and is an excellent choice for modal testing and analysis. Its light weight minimizes any mass loading influences that might result from larger sensors but still provides excellent response to short-duration, high g events. Taking precautions to properly mount and connect the sensor will provide years of reliable and accurate response.
First, users need to be aware that the output cable connector on the 2222C is one of the smallest available and as such must be handled with care. The connector is so small that some users are actually unaware there is a connector at the transducer! This connector is threaded directly into the device's body, and its center terminal makes contact to an internal metallic spring connected to the piezoelectric crystal stack. Below is a checklist that will allow you to get the most out of your 2222C.
The included adapter cable, 3093C-12, should also be used properly to maximize its lifetime.
The main, 10 ft cable should be secured within the first inch after the transition connection, and then can be routed to a charge amplifier like the popular Endevco 133.
