SA-611 is an amplifier for piezoelectric accelerometers, both charge type and pre-amplifier type; IEPE type.
It has current sources for IEPE type sensors, too. Its frequency range is from 0.2Hz to 30kHz, and maximum input is 10000pC or ±10 volts, so wide-range measurement is available.

- SA-611 has two inputs both 'CHARGE' for charge type sensors, and 'FET' for IEPE type sensors. For our sensors, six hundred series sensors are charge type, and seven hundred series sensors are IEPE type.
- The sensitivity setting by three digits digital switches makes the differences of each sensors sensitivity correct.
- And it has three ranges of 1, 10, and 100, so makes measuring ranges wider.
- Because SA-611 is light weight, compact, and it is driven by three types of power supplies built-in batteries(four AA batteries), external DC, and AC adaptor, SA-611 is able to be used in wide location of indoor or outdoor.
- With optional connecting plates, SA-611 is used as multi-channels amplifier easily and inexpensively. For three-axes sensors you use three units of SA-611 connecting for each axes.
