Hanwei DF3050 Fiber Optic Vibration Detector Now Available Through Intrako for Pipeline and Perimeter Security

Hanwei DF3050 Fiber Optic Vibration Detector Enters Regular Stock at Intrako

Intrako (Xi'an Yingzhuoke Industrial Equipment Co., Ltd.), the instrumentation brand of Shaanxi Qindiyuan Environmental Equipment Co., Ltd., has added the Hanwei DF3050 fiber optic vibration detector to its regular stock for oil and gas, utility and industrial security projects. The DF3050 converts a standard single-mode fiber cable into a continuous distributed vibration sensor, giving project teams a cost-efficient way to watch long pipelines, plant perimeters and remote assets without installing thousands of discrete detectors.

Fiber optic sensing has moved from laboratory pilots to mainstream industrial practice over the past five years, driven by tighter pipeline safety rules and by the falling cost of single-mode cable. Instead of relying on point devices that only protect a few metres of fence line, the DF3050 reads vibration signatures along the whole fiber run and reports the location of an event, which shortens patrol response times and reduces nuisance alarms caused by weather or wildlife.

How the DF3050 Works

The unit injects a 1550 nm laser pulse into a 9/125 um single-mode fiber and analyses the weak backscattered light. Mechanical disturbance such as digging, climbing or cable tampering changes the local optical phase, and the detector turns that change into an event with a distance tag. Because the sensing element is the fiber itself, the system is immune to electromagnetic interference, needs no power along the route, and keeps working in rain, dust and salt-spray environments where conventional electronics struggle.

Key Specifications

Typical Applications

• Oil and gas pipelines: early warning of third-party excavation, hot tapping attempts and anchor damage along buried or above-ground lines.
• Plant and depot perimeters: fence climbing detection for refineries, tank farms, chemical plants and LNG terminals.
• Power and utility sites: cable trench and substation intrusion monitoring where electrical noise rules out conventional sensors.
• Transport infrastructure: tunnel, bridge and railway right-of-way monitoring for impact and vandalism events.
• Data centres and warehouses: low-cost perimeter coverage for sites that cannot justify a full thermal camera network.

Why Buyers Choose This Model

• One processor covers up to 50 km of fiber, cutting hardware count and installation labour on long routes.
• Passive fiber sensing means no field power, no batteries and no electronics exposed to the weather.
• Distance-tagged alarms let control room staff send patrols straight to the event instead of walking the entire line.
• Open TCP/IP and IoT interfaces allow integration with existing SCADA, VMS and alarm management platforms.
• Rack-mounted 220 V AC or 12 V DC supply suits both control rooms and remote solar-powered cabinets.

Supply and Support from Intrako

Intrako keeps the Hanwei DF3050 available with a minimum order quantity of one unit, a typical delivery time of one week and T/T payment terms, which suits both pilot projects and framework orders. Our engineers support fiber route planning, cable selection, alarm threshold tuning and integration with third-party monitoring software, and we can quote project-specific configurations where longer range or tighter positioning accuracy is required.
