G-LINK-200-R

Rugged Wireless Accelerometer, 3-Axis, ASTM F2137 Compliant

The G-Link-200-R is a battery powered wireless 3-axis accelerometer with a rugged, weatherproof enclosure. This wireless accelerometer complies with ASTM F2137, making it specifically suited to monitor the dynamic characterizes of amusement rides and roller coasters. The G-Link-200-R provides extremely low noise waveform data, ideal for vibration, impact, and motion monitoring applications, as well as the Standardized Amusement Ride Characterization Test (SARC Test). For applications that do not require ASTM F2137 compliance, please visit the G-Link-200-8g or G-Link-200-40g page.

Lord wireless sensor networks are fast to deploy and provide reliable, lossless data throughput. These networks are proven to work in demanding industries where reliable data acquisition is critical.

Description

The G-Link-200-R is specifically designed to monitor the dynamic characteristics of amusement rides and roller coasters. The wireless sensor is ASTM F2137-18 compliant. An onboard triaxial accelerometer reports high-resolution waveform data with extremely low noise and drift.

LORD Sensing Wireless Sensor Networks enable simultaneous, high-speed sensing and data aggregation from scalable sensor networks. Our wireless sensing systems are ideal for test and measurement, remote monitoring, system performance analysis, and embedded applications.

Users can easily program nodes for continuous, or event- triggered sampling with the SensorConnect software. The optional web-based SensorCloud interface optimizes data aggregation, analysis, presentation, and alerts for sensor data from remote networks.
