DITEST SMARTPROFILE SENSOR

 

The DiTeSt SMARTprofile combined strain and temperature sensors are designed for distributed  deformation (average strain) and temperature monitoring over long distances

 

The DiTeSt SMARTprofile sensor consist of one or two bonded and two free single mode optical fibres embedded in a polyethylene thermoplastic profile. The bonded fibers are used for strain monitoring, while the free fibers are used for temperature measurements (quantitative if sensor deformation <0.2%, qualitative if sensor deformation >0.2%) and to compensate temperature effects on the bonded fibers. For redundancy, two fibers are included for both strain and temperature monitoring. The profile itself provides good mechanical, chemical and temperature resistance. The size of the profile makes the sensor easy to transport and install by fusing, gluing or clamping. The SMARTProfile sensor is designed for use in environments often found in civil, geotechnical and oil & gas applications. However, this sensor cannot be used in extreme temperature environments, nor in environments with high chemical pollution. It is not recommended for installation under permanent UV radiation (e.g. sunshine).

 

Kami sangat menyarankan anda untuk menggunakan data loggeratau data acquisition agar pemantauan menjadi lebih efisien dan cepat.
