Safety Precautions Adjustment Fiber Units Accessories Detection Position for Liquid-level Detection Fiber Unit (E32-D82F1) Use of E39-R3 Reflector Provided with E32-R21 The liquid-level detection position is 5.2 ±2 mm from the end of the fluororesin section. (Refer to the diagram on the right.) The liquid-level detection position varies with the surface tension of the liquid and the degree of wetness at the Fiber Unit’s detection position. 1. Use detergent to remove any dust or oil from the surfaces where tape is applied. Adhesive tape will not be attached properly if oil or dust remains on the surface. 2. The E39-R3 cannot be used in areas that are exposed to oil or chemicals.
5.2 ±2 mm (from the end of the fluororesin section) Liquid-level detection position Mounting method of Disconnection-resistant Protective Spiral Tubes (E39-F32 @ ) 1.Inser t the Fiber Unit into the Protective Spiral Tube from the head connector (threaded). Other Precautions Protective Spiral Tube Fiber Unit Liquid-level Detection Fiber Unit (E32-D82F1) 2. Push the fiber into the Protective Spiral Tube. The tube must be straight so that the fiber enters without twisting. Turn the Protective Spiral Tube, not the fiber. • Operation may become unstable in the following cases: 1. Bubbles stick to the cone of the sensing head. 2. Solute deposits on the cone of the sensing head. 3.
The liquid has a high viscosity. • There are some liquids, such as milky white liquids, for which detection is not possible. • Do not let the end of the fluororesin section bump into other objects. Damage to or deformation of the sensing head may cause unstable operation. • The product shall be used in the following conditions. Ambient pressure: -50 to +500 kPa • To use one-point teach mode (without object) Please carry out teaching where the detecting head is sunk into liquid. The sensitivity is set to 10% upper to the incident level in the liquid.
This setting method is effective in high degree of viscosity, because it becomes stable to the fluctuation of incident level when the liquid drops from the tip. • To use two-point teach mode (with/without object) Please teach where the detecting head is pulled up from liquid and next teach where it is sunk into liquid. This setting method is effective to a liquid which is easy to bubble at high temperature. • Don't use maximum sensitivity mode because a liquid may be undetectable.

Use the provided saddle to secure the end cap of the Protective Spiral Tube. (To secure the Protective Spiral Tube at a position other than the end cap, apply tape to the tube so that the portion becomes thicker in diameter.) Saddle Tube End cap Attaching the E39-F10 Fiber Connector Attach the Fiber Connecter as shown in the following figures. 1. Insert the Fiber Unit in the retention clip. 2. Insert the retention clip into the splice. Chemical and Oil-resistant, Liquid-level Detection Fiber Unit (E32-D82F1) Fluororesin shows strong chemical-resistant properties but is permeable if exposed to atmospheres with gaseous chemicals or water vapors, resulting in failure or damage.
Confirm applicability sufficiently before using the Fiber Unit in these environments. • The Fiber Units should be as close as possible when they are connected. The sensing distance is reduced by approximately 25% when Fiber Units are extended by the connector. • Only 2.2-mm-diameter fibers can be connected.
