This automatic optical fiber tensile testing system is designed for operator skill independent use in production and laboratory options. Two basic model configurations enable the user to choose between a setup for standard linear proof testing and with additional mandrels for rotary high strength testing.
The linear version is designed for production proof testing with forces as much as 22 N. Motorized clamps with carefully designed rubber inserts ensure that the secondary coating line will not be damaged in the testing process while at the same time eliminating the necessity for an external air supply. Amounts of pulling force, pulling speed and hold time are programmable and conveniently available to the operator through the built in LCD touch-screen control. Data from tests could be saved and accessed via the USB port or Ethernet interface.
Mandrels of the identical design as in NYFORS’ optical fiber recoaters may be easily mounted on the proof tester inside the rotary high strength configuration. The fiber is wrapped around the two mandrels which support it having a special clamping mechanism. By doing this higher loads can be applied onto the fiber, enabling breaking strength tests under controlled circumstances.
Adjustable clamp positioning facilitates testing using the highest force levels along with testing of short fiber lengths. The compact and lightweight weight design definitely makes the instrument easy to maneuver in a laboratory environment as well as integrate in a production work bench where space are at a premium. The machine is a compact and lightweight instrument ideal for testing the effectiveness of optical fibers as much as 30 N. The equipment is developed to meet all sorts of applications in which a strength test must be performed.
The machine was created with the user in your mind. The SZ stranding line is easily positioned in the guided linear clamps, and also the testing starts automatically having a “One Touch” go button. The built in microprocessor controls all the important parameters like pulling force, pulling speed and hold time. This enables to get a completely controlled test each time.
The machine could be connected to an outside PC, which enables access to all programmable parameters and settings. The device is adapted to stand-alone use or even to the integration into different subsystems. The equipment has an extensive capability of logging and saving information like pulling force, pulling speed and fiber diameter and other parameters.
Two recoat injector configurations can be found. The PTR307 uses an automated pump to inject the recoat material. The quantity of material dispensed by the automatic injector is controlled manually via the top-mounted “Inject” button or programmed into the machine making use of the tablet controller. The PTR307B features a manual recoat injection system that requires the consumer to manually dispense the recoat material to the mold cavity; another one injector for that PTR307B recoater is available below. Please note uojthk the automated injector is simply suitable for high-index recoat material, while the manual injector is compatible with both low- and high- index recoat material; both of them are sold separately below. Please contact Tech Support to learn more.
he manual injector could be mounted to compatible fiber recoaters using the 4-40 screws on the recoater housing (see photo to the correct). Make use of a 3/32″ hex factor to secure the injector prior to use. To get in touch the PTRRRM to the recoater mold, tighten the connector at the conclusion of the green plastic tubing, then loosen with a 1/4 consider permit rotation.
The injector comes with a distribution valve and 2-position selection lever for directing the flow of recoat material. A knurled dispensing screw with the internal plunger behaves 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 within the photo to the correct). Then, to inject the optical fiber coloring machine, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until close to the end from the travel range is reached. Avoid bottoming out your dispenser since this may damage the internal plunger; also be careful 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 as well as an acetone or alcohol cleaning means to fix collect any excess recoat material that flows from the mold.
