Description

EDAS-27HR has ultra-high resolution, large dynamic range, can output low-latency real-time data streams, supports large-capacity data storage, large-capacity data backup storage and multi-user real-time data service functions, and has small size, light weight and power consumption. Low characteristics. Achieve full coverage and docking from ultra-wideband seismometers, very wideband seismometers, broadband seismometers, short-period seismometers to strong earthquake accelerometers, fully meeting various earthquake observation applications. EDAS-27HR is a six-channel collector, including three ultra-high-resolution channels with a dynamic range exceeding 147dB (0-20Hz) and three high-resolution channels, plus six low-speed 27-bit acquisition channels. EDAS-27HR uses dual cards to store data internally, making data storage more reliable. It supports hot-swappable SD cards for easy data copying.

The EDAS-27HR input amplifier has three analog input channels, all using balanced differential input methods, which improves the EDAS-27HR’s ability to resist common mode interference. The EDAS-27HR ultra-high resolution channel is set with a differential range of +20V. The other three channels have four ranges of +20V, +10V, +5V and +2.5V. The range can be flexibly switched through the software. In addition to being connected to Gangzhen Technology In addition to the seismometers produced by the company, it can also be equipped with seismometers produced by third-party manufacturers.
