Tiltmeter (tilt sensor)
Angle sensor with temperature compensation
The Fiber Bragg Grating Tiltmeter is an angle variation measuring sensor that features good linearity, no hysteresis, and is temperature compensated by additional Fiber Bragg Grating (FBG). It is designed to measure small variations of angle towards the vertical with less demand on operational spectrum needs.
- 100% passive sensor without the need for power
- temperature compensation design
- excellent robustness and stability
100% passive sensor
Since the sensor does not need power, it easily monitors places without electricity and hazardous or inaccessible areas.
Temperature compensation
This FBG sensor is designed with additional FBG for temperature compensation which leads to smaller spectrum demands and consequently to a higher number of sensors per channel. The sensor design provides a significantly smaller footprint and weight.
Excellent long term stability
The Tiltmeter is highly durable and reliable even in demanding environments. This makes it especially suitable for a long term field operation.
Protected as IP68 rated devices
The IP68 rating guarantees complete dust tightness and protection against the effects of long immersion in water.
Immune to EMI/RFI
The fiber optic sensor enables operation in harsh environments and hazardous areas. The technology is passive, explosion safe, and immune to electromagnetic/radio frequency interference.
Intrinsic multiplexing capability
Thanks to the intrinsic multiplexing capability, many tiltmeters can be linked by a single optical fiber. This makes it suitable for inaccessible locations and large scale sensing networks.
Remote sensing
The angle sensor is very suitable for remote sensing, as it can be installed several kilometers away from the measurement unit.
Insensitivity to environmental induced noise
The sensor is inherently insensitive to environmental noise and is therefore suitable for measurements that could be distorted by ambient sound.
Large range of applications
The fiber optic Tiltmeter can be used in a large range of monitoring applications, such as slopes, dams, pylons, bridge pillars, etc.
Low installation costs
Installation and cabling for such sensor networks are much less expensive and cumbersome than comparable electronic gauge networks.
Connectivity
The sensor can be used alone or in large sensing networks.
