1 _ MENHIR STRONG MOTION SYSTEM

2 MENHIR STRONG MOTION SYSTEM MENHIR SM (Strong Motion) is based on a new high performance and versatile platform for industrial, geotechnical, vibrational and strong motion applications requiring easy-to-use but highly reliable instrumentation solutions. Besides the outstanding measurement performance, MENHIR provides a very intuitive means to analyze measurement data and generates tailored expert reports in compliance with relevant norms and standards. MENHIR SM comes in a very compact but robust form factor including a triaxial MEMS accelerometer. It can be configured in modern IoT-compliant network topologies using both wired and wireless communication channels. MENHIR SM comes along with an onboard HTTP Server with TLS/SSL internet security for set up and management of the system. Each gauge is accurately graduated and has holes for easy fastening to walls, piers and other structures. FEATURES Embedded 3-channel MEMS acceleration sensor Sensor Bus (RS-485) for additional external sensors 24-bit Delta Sigma Converters, multiple sample rates Versatile Connectivity (Ethernet and Wireless) for data communication and alarm notification Highly Secure SSH and SSL Internet Protoco Built-in GPS, NTP and IEEE PTP Embedded Battery and Charger for autonomous operation Transient and EMI/RFI protection IP67 rugged enclosure MENHIR STRONG MOTION SYSTEM 2
