This automatic optical fiber tensile testing system is ideal for operator skill independent use in production and laboratory settings. Two basic model configurations allow 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 ideal for production proof testing with forces approximately 22 N. Motorized clamps with carefully designed rubber inserts be sure that the SZ stranding line is not really damaged in the testing process while concurrently eliminating the necessity for another air supply. Degrees of pulling force, pulling speed and hold time are programmable and conveniently accessible to the operator through the built-in LCD touch-screen control. Data from tests could be saved and accessed using the USB port or Ethernet interface.
Mandrels of the identical design as with NYFORS’ optical fiber recoaters could be mounted on the proof tester in the rotary high strength configuration. The fiber is wrapped around the two mandrels which support it with a special clamping mechanism. By doing this higher loads does apply to 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 light-weight weight design definitely makes the instrument easy to maneuver in a laboratory environment and also to integrate in a production work bench where space are at reasonably limited. The machine is really a compact and lightweight instrument ideal for testing the potency of optical fibers approximately 30 N. The device is developed to meet all types of applications when a strength test must be performed.
The device is made with the user in mind. The FTTH cable production line is definitely put into the guided linear clamps, and the testing starts automatically having a “One Touch” go button. The built in microprocessor controls each of the important parameters such as pulling force, pulling speed and hold time. This enables for a completely controlled test every time.
The device may be attached to an outside PC, which enables use of all programmable parameters and settings. The equipment is adapted to stand-alone use or to the integration into different subsystems. The device has an extensive capability of logging and saving information like pulling force, pulling speed and fiber diameter as well as 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 from the automatic injector is controlled yourself via the top-mounted “Inject” button or programmed to the machine using the tablet controller. The PTR307B comes with a manual recoat injection system that requires an individual to manually dispense the recoat material into the mold cavity; a replacement injector for the PTR307B recoater can be obtained below. Take note uojthk the automatic injector is just compatible with high-index recoat material, while the manual injector is compatible with both low- and- index recoat material; they are both sold separately below. Please contact Tech Support for more information.
he manual injector can be mounted to compatible fiber recoaters via the 4-40 screws on the recoater housing (see photo to the correct). Use a 3/32″ hex key to secure the injector just before use. To get in touch the PTRRRM for the recoater mold, tighten the connector at the end of the green plastic tubing, then loosen by a 1/4 turn to allow for 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 having an internal plunger acts 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 inside the photo to the correct). Then, to inject the optical fiber proof-testing machine, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until nearby the end of the travel range is reached. Avoid bottoming out your dispenser since this may damage the inner plunger; also take care when re-engaging the threads in order to avoid cross threading the dispensing screw. Several fill/inject steps may be required until air is displaced inside the system. Use lens tissue plus an acetone or alcohol cleaning answer to collect any excess recoat material that flows from your mold.
