Deicy AR-60ST8D 8-channel Dynamic Strain/DC Voltage Input Amplifier Module

Manufacturer: DEICY Co., Ltd.
Model: AR-60ST8D

Features

This is a DC application type 8-channel dynamic strain/DC voltage input module for the DR-900 series.
The low-pass filter uses a digital filter calculated by DSP.
Both the measurement range and the low-pass filter can be configured independently for each channel, and as a result, users gain greater flexibility. Moreover, this setup allows precise tuning per channel, while at the same time improving control and efficiency. In addition, engineers can optimize performance more easily, therefore achieving more accurate and reliable measurements.
