Fiber Optic Vibration Sensors

Raycom Fiber Optic Sensors are a complete sensing solution that starts at the point of measurement and ends by providing digital data and alarms. Our fiber optic sensor is used for vibration, acceleration, pressure and temperature sensing. As with all of our products, it uses photons (i.e. light), which makes it intrinsically safe and can operate in many harsh environments.

Product Description

Fiber Optic Vibration Sensor

Raycom fiber optic vibration sensor is a complete sensing solution that starts at the point of measurement and ends by providing digital data and alarms. Our fiber optic vibration sensor is used for vibration, acceleration, pressure and temperature sensing. As with all of our products, it uses photons (i.e. light), which makes it intrinsically safe and can operate in many harsh environments.

The RF960-4 is a 4-zone Fiber Optic Intrusion Detection System designed to detect intrusions into the perimeters and borders on the basis of the principle of laser interference. It adopts optical fiber vibration sensing technology, to detect and notify any intrusion attempt such as climbing, cutting sabotage the fence or disassembles the system. Furthermore, it has strong anti-disturb ability to eliminate environment nuisance alarms and can be immune to electromagnetic interference, lightning and storms.

The fiber optic vibration sensor is composed of RF960-4 host and several passive terminals. The host adopts 19 inch standard chassis, every two zones corresponds to an optical output interface and 2 optical input interfaces. By default, RF960-4 fiber optic vibration sensor supports 4 contact closure alarm outputs, the contact closure output can be extended and contact closure input can be also supported by choosing auxiliary card (declared before order). It is suitable for complex terrain, ammunition depots, ware houses, inflammable or explosive areas.

Application

As shown in Figure 1, the fiber optic vibration sensor host, installed in the central office, located at one terminal of all zones. The 1 piece of 8 core fiber cable are deployed, extending to one direction one by one. Each cable connects can arrange four zones.

As shown in figure 2 shows, from the central office, the optical fiber buses extend toward to both sides. Each fiber cable can deploy 2 zones.

In some application, we can use the connection with only one optical cable. It adopts one 8-core optical fiber cable, one RFM007-G, two RFM003-G, one RFM009-G and one RFM001-G.
