This Optical Fiber Proof-Testing Machine is ideal for operator skill independent use in production and laboratory settings. Two basic model configurations enable the user to select between a setup for standard linear proof testing along with additional mandrels for rotary high strength testing.
The linear version is made for production proof testing with forces as much as 22 N. Motorized clamps with carefully designed rubber inserts be sure that the fiber coating will not be damaged inside the testing process while at the same time eliminating the requirement for another air supply. Amounts of pulling force, pulling speed and hold time are programmable and conveniently offered to the operator from the built in LCD touchscreen display control. Data from tests can be saved and accessed through the USB port or Ethernet interface.
Mandrels of the same design as in NYFORS’ optical fiber recoaters could be mounted on the proof tester in the rotary high strength configuration. The fiber is wrapped across the two mandrels which support it using a special clamping mechanism. This way much higher loads can be applied onto the fiber, enabling breaking strength tests under controlled circumstances.
Adjustable clamp positioning facilitates testing with the highest force levels in addition to testing of short fiber lengths. The compact and lightweight weight design helps make the instrument easy to maneuver in a laboratory environment and to integrate in a production work bench where space is at a premium. The machine is actually a compact and lightweight instrument perfect for testing the effectiveness of optical fibers as much as 30 N. The machine is created to meet all kinds of applications when a strength test needs to be performed.
The equipment was created using the user in mind. The fiber is easily positioned in the guided linear clamps, and the testing starts automatically using a “One Touch” go button. The built-in microprocessor controls all the important parameters such as pulling force, pulling speed and hold time. This allows for any completely controlled test each and every time.
The Optical Fiber Proof-Testing Machine may be linked to another PC, which enables access to all programmable parameters and settings. The equipment is adapted to face-alone use or to the integration into different subsystems. The device posseses an extensive capacity for logging and saving information such as pulling force, pulling speed and fiber diameter and other parameters.
Two recoat injector configurations can be purchased. The PTR307 uses a computerized pump to inject the recoat material. The volume of material dispensed through the automatic injector is controlled by hand through the top-mounted “Inject” button or programmed into the machine utilizing the tablet controller. The PTR307B comes with a manual recoat injection system that requires the fseejm to manually dispense the recoat material in to the mold cavity; another one injector for the PTR307B recoater can be obtained below. Please note the automatic injector is simply suitable for high-index recoat material, as the manual injector works with both low- and high- index recoat material; they are both sold separately below. Please contact Tech Support for additional information.
he manual injector can be mounted to compatible Secondary Coating Line through the 4-40 screws on the recoater housing (see photo to the right). Utilize a 3/32″ hex answer to secure the injector before use. To get in touch the PTRRRM for the recoater mold, tighten the connector at the conclusion of the green plastic tubing, then loosen with a 1/4 consider allow for rotation.
The injector comes with a distribution valve and two-position selection lever for directing the flow of recoat material. A knurled dispensing screw with an internal plunger works as a syringe for that recoat material. To fill the syringe, point the lever downward (i.e., toward the recoat bottle), then rotate the knurled dispensing screw counterclockwise until it spins freely to fill the syringe (shown in the photo off to the right). Then, to inject the recoat material in to the mold, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until close to the end of the travel range is reached. Avoid bottoming the dispenser since this may damage the interior plunger; also take care when re-engaging the threads to avoid cross threading the dispensing screw. Several fill/inject steps may be needed until air is displaced inside the system. Use lens tissue and an acetone or alcohol cleaning solution to collect any excess recoat material that flows from your mold.
