SHOWA SOKKI 4035-50 Charge Amplifier for Vibration Measurement [General-purpose charge amplifier]
Made in Japan
Manufacturer: SHOWA SOKKI
Model: 4035-50
Features
The charge amplifier MODEL-4035-50 is a high-precision charge amplifier that converts the charge signal output from the detector into a voltage signal. Various analyzes are possible by connecting. Please try the low-cost, high-precision charge amplifier as a charge amplifier for measurement and vibration monitoring of lines, etc.”
- High precision and low price are realized.
- A dynamic range of 100 dB or more, and can handle a wide range of acceleration from minute to large acceleration.
- A charge amplifier that is resistant to minute vibrations due to its low-noise design.
- Unnecessary noise components can be cut with high-pass and low-pass filters.
- Compatible with charge output type and preamp built-in type acceleration sensors.
- Measurement is possible from 1CH by using an AC adapter.
- A small, lightweight, high-performance charge amplifier with a built-in 7-stage range.
- Compatible with sensors with built-in amplifiers.
