SIGMA Digital
Product Overview
In combining a standard three component SIGMA accelerometer with our well proven 24-bit TAU digitizer, this Digital SIMGA is an accelerometer with a fully digital output. This two-in-one package eliminates the need for an extrernal digitizer, thereby saving valuable deployment space. It also makes installation extremely easy, as there is no need to handle bulky seismometer cables. In conjunction with our OMEGA control and data acquisition software, this accelerometer can be fully remotely controlled and operated. Three available user interfaces (10/100 Base-ehternet, USB and Serial RS232) makes communication with this instrument easy and reliable.
