This automatic optical fiber tensile testing system is ideal for operator skill independent use in production and laboratory options. Two basic model configurations enable the user to choose between a set up 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 approximately 22 N. Motorized clamps with carefully designed rubber inserts be sure that the optical fiber ribbon machine will not be damaged inside the testing process while simultaneously eliminating the requirement for another 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 can be saved and accessed using the USB port or Ethernet interface.
Mandrels the exact same design as with NYFORS’ optical fiber recoaters can easily be mounted on the proof tester inside the rotary high strength configuration. The fiber is wrapped round the two mandrels which support it with a special clamping mechanism. By doing this much higher loads does apply to the fiber, enabling breaking strength tests under controlled circumstances.
Adjustable clamp positioning facilitates testing with all the highest force levels in addition to testing of short fiber lengths. The compact and light-weight weight design makes the instrument easy to move around in a laboratory environment and also to integrate in a production work bench where space are at a premium. The machine is really a compact and lightweight instrument perfect for testing the effectiveness of optical fibers as much as 30 N. The device is designed to meet all kinds of applications in which a strength test has to be performed.
The equipment is designed with all the user in mind. The SZ stranding line is definitely positioned in the guided linear clamps, and also the testing starts automatically having a “One Touch” go button. The built-in microprocessor controls each of the important parameters like pulling force, pulling speed and hold time. This enables for any completely controlled test each and every time.
The device may be connected to an outside PC, which enables usage of all programmable parameters and settings. The device is adapted to face-alone use or to the integration into different subsystems. The device comes with an extensive capacity for logging and saving information such as pulling force, pulling speed and fiber diameter along with other parameters.
Two recoat injector configurations are available. The PTR307 uses a computerized pump to inject the recoat material. The quantity of material dispensed from the automatic injector is controlled yourself using 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; a replacement injector for your PTR307B recoater is available below. Take note uojthk the automatic injector is simply compatible with high-index recoat material, whilst the manual injector works with both low- and- index recoat material; they are both sold separately below. Please contact Tech Support to learn more.
he manual injector may be mounted to compatible fiber recoaters using the 4-40 screws on the recoater housing (see photo to the right). Make use of a 3/32″ hex key to secure the injector prior to use. For connecting the PTRRRM towards the recoater mold, tighten the connector at the end of the green plastic tubing, then loosen by way of a 1/4 choose permit rotation.
The injector comes with a distribution valve as well as 2-position selection lever for directing the flow of recoat material. A knurled dispensing screw with the internal plunger works as a syringe for the 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 Secondary coating line, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until near the end in the travel range is reached. Avoid bottoming the dispenser since this may damage the internal plunger; also take care when re-engaging the threads in order to avoid cross threading the dispensing screw. Several fill/inject steps may be needed until air is displaced within the system. Use lens tissue plus an acetone or alcohol cleaning means to fix collect any excess recoat material that flows through the mold.
