Model:
Standard specification:
Purpose: A reliable and high performance Raman Time Domain Reflectance (OTDR) demodulator for field application. Measure the temperature profile along the whole temperature sensing cable.
 
DiTemp Temperature Sensing Optical Cable Reader
High precision and long distance
Distributed Optical Fiber Temperature Measurement System (DTS)
Suitable for field application
 
DiTemp distributed temperature sensing optical cable reader (also called demodulator) is used to measure the temperature distributed along the whole length of optical fiber temperature sensing optical cable. The maximum length of optical cable is 30 kilometers, the spatial resolution is 1 meter, and the measurement time is 10 seconds.
 
It is available in multi-mode and single-mode versions. This rack mountable reader can be used with external multiplexers (4, 8, 16 channels), relay modules and automatic trip detection system (ATTS).
 
Depending on configuration and redundancy, the DiTemp Reader has been rated as a Safety Integrity Level (SIL) 1 or SIL 2 device.
 
This system can be widely used in applications requiring distributed temperature sensing, such as concrete temperature monitoring in large structures, leakage detection of pipelines, leakage monitoring of dams and dams, waste disposal sites, intelligent buildings, to name a few.
