Performance Specifications

| ||
| Minimum Force | Lower limit of impact force desired. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| |||
| Maximum Force | Upper limit of impact force desired. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Upper Limit of Frequency Range | This is the highest frequency for which the response will be tested. Many impact hammers come with tips of different material and different hardness. These different hardness tips will induce different responses. Typically the hardest tips are used to measure response at the highest frequencies. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Minimum Pulse Duration | Pulse duration is the length of time that the impact hammer tip is imparting force to the structure. In general, harder tips will deform less than softer tips during impact and will therefore have a shorter pulse duration. | ||

|
|
| ||
| Hand Operation | Styled and used like a standard hand-tool hammer. Force is manually applied. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Remote or Automatic Operation | Hammer strikes are controlled remotely, usually electrically. Automatic impact hammers may be used when response needs to be measured for a precise pattern or frequency of impacts. Tool is fixtured in place. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Various Tips Included | Range of tips for different force / response time characteristics. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Additional Mass Included? | Additional mass can be attached to the hammer head to increase excitation force. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Complete Kit / Signal Conditioner | Hammer includes necessary additional equipment for signal conditioning and/or analysis. This would include components such as an accelerometer to be attached to the structure being excited, signal conditioners for the transducer signals, and a multichannel analyzer for the transducer and the accelerometer. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||

|
| ||
| Operating Temperature | The temperature range over which the device must operate. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
