Based on the measurement of an absolute parameter - the Bragg wavelength - independent of power fluctua tions. 1.1.3 Applications HBM FiberSensing temperature sensors can be used in several temperature measuring applications. They are particularly suited for temperature mapping in large struc tures (SHM). : Industry...
HBM FiberSensing, S.A. concentrates all optical sensing activity of HBM and is an ISO 9001:2008 certified com pany. 1.1.5 Accessories The implementation of complex sensing networks in large structures is made simpler with HBM FiberSensing accessories.

Its design includes ruggedized cables that resist such an environment. Nevertheless, whenever possible, further protection of cables should be performed on the cables path. Prepare the sensor cables path with an appropriate, flexi ble and resistant tube. FS63 A4261-3.2 HBM: public...

Sensor Installation Fig. 2.1 Fig. 2.2 Depending on the control on the construction site, HBM FiberSensing suggests two different solutions regarding the access to the sensor connections: If the stripping of the concrete can be closely controlled, the protection tube can pass directly through a hole in the formwork (Fig.
Page 10
Fig. 2.3 Fig. 2.4 If the stripping cannot be controlled, it is advisable to use embedded protection boxes. Fix the box to the formwork with screws that can be later on removed before the stripping. FS63 A4261-3.2 HBM: public...

Sensor Installation Fig. 2.5 Fig. 2.6 Important Make sure the construction workers are instructed that it is necessary to disconnect the boxes from the formwork before removing it. FS63 A4261-3.2 HBM: public...
Place it on the structure with the desired orientation. Fix the buffer as close to the sensor as possible making sure that the interface of the sensor and the buffer is not being forced. Fig. 2.7 Fig. 2.8 FS63 A4261-3.2 HBM: public...

Control the path of the buffers with plastic wire clamps ensuring that the exposed buffers (before entering the protection tube) do not have tight curves and that it is protected by the reinforcement during the concreting operations and vibration (Fig. 2.9). Fig. 2.9 FS63 A4261-3.2 HBM: public...

The concreting process is a tough operation on the sen sors, specially the vibration of the concrete. One way of protecting the sensors from the vibrating equipment, as well as from the heavier aggregates, is to place a net on top of the sensors location. FS63 A4261-3.2 HBM: public...
