All Geosense Tiltmeters use MEMS technology. This stands for Micro Electronic Measurement System. With our range of Tilt measuring products, this technology has superseded the Servo-Accelerometer technology (in particular relation to Tiltmeters, it was also referred to Electro-levels).
Biaxial or Uniaxial
All Tiltmeters have the option of being supplied with Single or Dual axis Tilt boards. Biaxial is generally slightly more expensive so depending on your application or measurement requirements, you are able to make a decision on which would be better suited and potentially save some cost where you can get by with Single Axis measurements.
Standard Tiltmeters are supplied in an IP66 enclosure meaning they are protected against strong jets of water (i.e. heavy rain). If there is any chance at all of the Tiltmeter becoming submersed, a Submersible Tiltmeter (IP68 to 200m) should be used.
Our Tiltmeters have been manufactured to meet the Electromagnetic Compatibility Directive 2004/108/EC, to ensure there is no chance of being affected by electrical noise on any site. When a cable is being routed from each sensor there are specific requirements that need to be met with regards to the type of cable and how it is terminated. Geosense provide a Low Smoke Halogen Free cable with a braid with all Tiltmeters, Tiltbeams and In-Place Inclinometers. When the cable needs to be spliced it is important to contact Geosense to supply an EMC splice kit which will ensure the EMC compliance is throughout the cable route.
Geosense has a wide range of Wireless options available which are all part of the Wi-SOS family of products. Our Tiltmeters are compatible with many of these models depending on the arrangement that is required of them. Here are some typical arrangements and which WI-SOS model and Tilt variation would be best to use:
- Standalone Tiltmeter with limited or no access to it = 4-20mA Tiltmeter w/ WI-SOS 100.
- Array of Tiltmeters within a radius of 800m with good line of sight = 4-20mA Tiltmeter with WI-SOS 400 nodes for each Tiltmeter and Gateway in central location.
- String of bussed In-Place Inclinometers with limited or no access to the borehole location = WI-SOS 300 sending signal to central Geologger location.
