Real-time movement monitor provides long-term settlement monitoring

Geotechnical Observations has added a tilt sensor to its range of products to offer real-time monitoring of movement.

The wireless monitor can be mounted on a building and used alone or as a network of up to 32 units to check for any movement within a structure.

According to Geotechnical Observations’ managing director Dr Andrew Ridley, the main difference of this system over others available on the market is the battery life. “If the monitor is set to report every five seconds then the battery will last a month, but if the monitoring period is reduced to one-minute intervals, it will last a year,” he explained. “At five-minute intervals, the battery will last a number of years. This means the system could be used for long-term settlement monitoring well beyond the construction phase of work.”

The monitor feeds information via GPRS to a computer monitoring point which gives a visual display of the status of each unit. The display can be improved by using photographs of the building to allow any problems to be easily located. Text and email alerts can also be set up.

The system has a 150m range between different units and the data collection point as it uses freeto-air radio.
