2-channel Sensor Amplifier
SR-2210

The SR-2210 is a 2-channel sensor amplifier for inputting to analyzers and recorders such as DAT that do not support constant current drive (CCLD) sensors.
It can connect to compact and versatile BNC cable compatible MI-3111, MI-3170* micro hump preamplifiers and NP-3000 series accelerometers.
Since the SR-2210 is compact, lightweight, and battery-operated, it allows for easy measurement preparation and enables the construction of a low-cost measurement system.

Notice of Discontinuation of Sales

The SR-2210 has been discontinued. Please check the successor product (SR-2210A) here.

Features

  • With 2-channel input, simultaneous measurement of sound pressure, vibration, and sound insulation is possible.

  • Corresponding to frequency correction characteristics (A, C, Z(FLAT)).

  • Dual power supply method: battery-operated / AC adapter (optional: PB-7090)

  • Can be stacked and fixed, supports multi-channeling.
