Biocommunication Electronics model 215
Measuring force, positon, or torque - when used with strain gage transducers.
Measuring oral or nasal pressure (speech research) when used with aerodynamic transducers.
Can also be used with microphones, especially high impedence types (or dynamic mics with matching transformer. Can be used with preamplifiers, such as EMG, that require additional gain and filtering. Can also be used with accelerometers.
