The SR-2210 sensor amplifier accepts constant-current line drive sensors and connects the signal to analyzers and recorders that would not otherwise be compatible with constant-current sensors.
The units connects directly with BNC connectors to ONO's model MI-3111 microphone preamplifiers and NP-3000 series of accelerometers.
With compact, light-weight, battery operation, it can save for preparation of measurement.
