Yokogawa DTSX200-N0EN – Distributed Fiber Optic Temperature Sensing System | DTSX200 Platform
Engineering Background
The DTSX200-N0EN is Yokogawa’s second-generation distributed temperature sensing (DTS) platform, engineered for continuous, real-time temperature profiling along the full length of a fiber optic cable. Leveraging Raman backscattering OTDR technology, it delivers spatial temperature maps across distances up to 30 km with sub-meter resolution — without any field-side electronics or power at the sensing point.
Product Positioning
Designed for procurement engineers and system integrators in power utilities, oil & gas pipelines, subsea infrastructure, tunnel safety, and data center hot-spot monitoring. The DTSX200-N0EN is the standard single-channel variant of the DTSX200 family, offering a balance of measurement range, accuracy, and cost-efficiency for demanding industrial environments.

- Flexible Fiber Compatibility: Supports both SMF and MMF, allowing reuse of existing installed fiber infrastructure.
System Architecture & Signal Flow
The DTSX200-N0EN injects a pulsed laser signal into the sensing fiber. Raman backscatter photons — whose intensity ratio (Stokes / Anti-Stokes) is temperature-dependent — are captured by the internal OTDR receiver. The DSP engine converts time-of-flight data into a spatially resolved temperature profile, which is stored internally and transmitted via Ethernet to the DTSX Manager software or directly to a DCS/SCADA host. Alarm zones are configurable per segment, with relay outputs for hardwired interlock integration.

Technical FAQ
Q: What fiber type does the DTSX200-N0EN require?
A: It supports both single-mode (G.652D) and multi-mode (OM1/OM2) fiber. Multi-mode fiber provides shorter range but lower cost; single-mode is recommended for distances beyond 10 km.
Q: Can the DTSX200-N0EN integrate with a Yokogawa CENTUM VP DCS?
A: Yes. Native integration is available via OPC-DA/UA server. Modbus TCP is also supported for third-party DCS/SCADA systems.
Q: What is the minimum measurement cycle time?
A: Approximately 1 minute for a full 30 km scan. Shorter fiber lengths yield proportionally faster cycle times.
Q: Is the DTSX200-N0EN suitable for hazardous area installation?
A: The N0EN suffix denotes a standard (non-Ex) unit. For Zone 1/Zone 2 or Class I Div 1/2 installations, consult Konmask for the appropriate DTSX200 Ex-rated variant.
Q: Does Konmask provide calibration certificates?
A: Yes. All units are supplied with the original Yokogawa factory calibration certificate. Third-party re-calibration can be arranged on request.
