DiTemp Reading Unit
HIGH-ACCURACY AND LONG RANGE DISTRIBUTED TEMPERATURE SENSING SYSTEM (DTS)
Reliable and high performance Raman OTDR interrogator for field applications.
Measures full temperature profile over fiber optic sensing cables.
The DiTemp Reading Unit is designed for distributed temperature measurements for distances of up to 30km, with 1m spatial resolution and 10s measurement time. It is available in multimode and singlemode versions. This rack-mountable unit can be complemented with external multiplexers (4, 8, 16 channels), a relay module and a self-testing system (ATTS).
Depending on configuration and redundancy, the DiTemp system has been assessed as SIL 1 or SIL 2 compatible (Safety Integrity Level ).
The system is used in a wide range of applications that require distributed temperature sensing, such as temperature monitoring of concrete in massive structures, leakage detection of pipelines, seepage monitoring in dams and levees, waste disposal sites, smart buildings, just to name a few.
