Structural Monitoring

Historic Building Monitoring

Our Historic Building Monitoring services may utilise any of our devices like the SA-CM100 or the SA-TM200. The devices are fixed in place with a special glue that is removed after application with a solvent that leaves no trace yet allows zero movement when fixed in monitoring position. The devices will normally be a GSM, battery powered transmitting device that gets installed across the crack or on the face of the building that requires monitoring.

How it works:

After installation and being set to zero the historic building monitoring device wakes up at set intervals to report. The default setting is every 6 hours – this gives 4 reports per 24hrs. The report will show a line graph detailing a time stamp of the triggered report, and showing the distance of movement detected.

Each time the device wakes up and takes a measurement, it also sends the report to our servers. Our report to your email, or for premium customers; to your dashboard will be set at the intervals you choose: Every 6 hours, Every 12 hours, Every 24 hours, Every week or Every month.

For premium customers, the device can also be set to trigger an alarm if sufficient movement is detected above a certain threshold. This alarm could be via SMS, or a Dashboard alert, or an Email if required. 

Any settings changes will result in a faster resource usage than our guaranteed 1 Yr in the field between charges. Any call out to recharge could result in service charges, all of which will be made clear at the time of the initial setup.

In areas of low GSM signal, we have extenders for the aerial but these will use up battery fairly quickly. We also have a WiFi version coming out soon, that can be mains powered as well. Our approach to all situations is to get the data, make sure the data is not compromised in any way, and report on it to the best of our ability. We pride ourselves in developing solutions to assist our customers.

Not to be compared with a cheap manual telltale marker, what we offer is a state of the art, British Designed and Made, High Tech reporting Crack Monitoring device.
