This Secondary Coating Line is ideal for operator skill independent use within production and laboratory settings. Two basic model configurations allow the user to choose between a set up for standard linear proof testing 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 fiber coating is not really damaged within the testing process while at the same time eliminating the necessity 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 touch screen control. Data from tests may be saved and accessed through the USB port or Ethernet interface.
Mandrels of the identical design as with NYFORS’ optical fiber recoaters can easily be mounted on the proof tester within the rotary high strength configuration. The fiber is wrapped across the two mandrels which support it having a special clamping mechanism. In this way much higher loads can be applied on 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 light weight design helps make the instrument easy to maneuver in a laboratory environment as well as integrate in a production work bench where space are at reduced. The equipment is really a compact and lightweight instrument suitable for testing the potency of optical fibers approximately 30 N. The device is designed to meet all sorts of applications where a strength test must be performed.
The device is made using the user in mind. The fiber is readily 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 permits for a completely controlled test every time.
The Sheathing Line may be attached to an external PC, which enables use of all programmable parameters and settings. The device is adapted to face-alone use or to the integration into different subsystems. The machine has an extensive capability of logging and saving information such as pulling force, pulling speed and fiber diameter along with 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 manually via the top-mounted “Inject” button or programmed in to the machine making use of the tablet controller. The PTR307B includes a manual recoat injection system that needs the fseejm to manually dispense the recoat material to the mold cavity; a replacement injector for that PTR307B recoater can be obtained below. Please be aware the automatic injector is only appropriate 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 to learn more.
he manual injector may be mounted to compatible Optical Fiber Proof-Testing Machine through the 4-40 screws on the recoater housing (see photo off to the right). Utilize a 3/32″ hex answer to secure the injector just before use. To connect the PTRRRM towards the recoater mold, tighten the connector at the conclusion of the green plastic tubing, then loosen by way of a 1/4 turn to allow for rotation.
The injector is equipped with a distribution valve and 2-position selection lever for directing the flow of recoat material. A knurled dispensing screw with the 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 within the photo off to the right). Then, to inject the recoat material into the mold, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until near the end from the travel range is reached. Avoid bottoming out your dispenser since this may damage the inner plunger; also be careful when re-engaging the threads to prevent cross threading the dispensing screw. Several fill/inject steps may be needed until air is displaced in the system. Use lens tissue and an acetone or alcohol cleaning means to fix collect any excess recoat material that flows through the mold.
