2-channel sensor amplifier
SR-2210

The SR-2210 is a 2-channel sensor amplifier for inputting sensors into analyzers or recorders such as DATs that do not support constant current drive (CCLD).
It can connect to the MI-3111, MI-3170* microphone preamplifiers and NP-3000 series Accelerometer, which are small and use a standard BNC cable.
The SR-2210 is small, lightweight, and battery-powered, making it easy to set up for measurements and allowing for the construction of a low-cost measurement system.

Features

  • With two-channel input, simultaneous measurement of "sound pressure and vibration" and "sound insulation" is possible.

  • Supports frequency weighting characteristics (A, C, Z (FLAT)).

  • Dual power supply system: battery powered / AC adapter (optional: PB-7090)

  • Stackable and secure, supports multi-channel configurations.
