CalSens SL offers processes and structures monitoring services, advice in the safety evaluation and decision making services to guarantee a proper working.
CalSens SL is a firm with technological base and spin-off of the Technical University of València. It is born from the union of professionals from telecommunications and civil engineering who have been working together from 2004 in photonic technology research projects applied to processes and structures monitoring.
Products
Structural Health Monitoring
CALSENS offers Structural Health Monitoring applied to aerospace, transport, energy, construction… This service includes all stages from the sensors manufacturing to data gathering and final assessment
- Optical fiber sensors manufacturing
- Instalation of grating sensors and monitoring system
- Monitoring system maintenance.
- Data gathering and management.
- Data analysis and assessment of the monitored component.
CALSENS also develops protocols for evaluation from the data obtained in the monitoring system, for new implantation processes as much as for operating processes.
High Temperature fiber optic sensors
CALSENS optical sensor of high temperature equals electric thermocouples, with the advantage of the technology of the optic fiber (life expectancy, stability, immunity to electromagnetic interferences, little weight and diameter, possibility of multiplexing of sensors in one cable. The FBG receives a regenerating process (RFBG), patent pending, which allows measurement of temperatures up to 1200 º C The sensor packaging offers stability in harsh environments, and also corrosion and mechanical resistance.
Photonics sensors manufacturing
CalSens team has a broad experience in the handling and design of photonic optical systems and devices. The developed sensors use the following technologies: FBGs, interferometers, Rayleigh Scattering and Stimulated Brillouin and Raman Scattering. The most suitable technology will be recommended according to the user’s specific needs.
It´s main applications are:
- Structural Health Monitoring
- Civil Engineering
- Aerospace
- Biomedical
- Energy
- Heritage structures
Nummerical models
Numerical models have become an essential tool to solve problems in most of engineering scenarios. CALSENS team has extensive experience in the development of nummerical models not only for structural health assessment, but to calibrate behaviors and in support of structural monitoring results.
Nummerical finite element modelled by CALSENS are about different topics: evolution of loads during the construction process for tall buildings, reinforcing concrete columns with steel elements and composites, forensic engineering, geotechnical engineering, heritage structures, structures submitted to fire, among others.
Health Monitoring in conveyor mining
One of the most important problems in mining is the failure of the conveyor belts. These failures are caused by overheating of the supporting rollers that can induce fires, reaching large economic losses and sometimes, human losses.
CALSENS has developed a new monitoring system of conveyor belts for mining sector. This system is capable of detecting a malfunction of the supporting rollers of the belt prematurely and thus avoid possible fires and their devastating consequences.
The monitoring system is based on optical fiber technology.
Characterizing subterranean element stiffness
CALSENS team has a broad experience in geotechnical engineering. Characterization subterranean element stiffness by GDS is one of our services. The tests performed consist in the emission of a surface wave of computerized frequency and in its reception to three low frequency geophones (2Hz) aligned with the vibrator and placed 0,50, 1,00 and 1,50 metres from the emisor. The analog signal of these geophones becomes digitalized and registered regarding time. On these data a Fourier transform is performed in order to determine the stage of the signal received by each geophone with respect to the vibrator. Thus, basing on the surface wave transmission theory through a flexible solid, the “Gmax” shear modulus is determined in different depths, defining a Modulus G vs Depth for the observation point.
